While the oral polio vaccine is indeed associated with shedding and vaccine associated disease, that doesn’t happen with MMR. Experts don’t even recommend any restrictions for use of the MMR vaccine for household contacts of people who are immunosuppressed. And yes, your kids can even visit a cancer patient if they just had their MMR, as long as they don’t have RSV, the flu, or some other contagious disease.
What about the fact that a study once found measles virus RNA in the urine of of kids who had recently been vaccinated? Doesn’t that mean that they were shedding the vaccine virus?
No. It doesn’t.
To be considered shedding, those measles virus RNA particles in their urine would have to be contagious. Now, measles is spread by respiratory secretions. So how are measles virus RNA particles in urine going to become airborne and get someone else sick?
But what about that case in Canada? Anti-vaccine folks like to bring this up when they talk about shedding. In 2013, there was a case of vaccine-associated measles. That proves that the vaccine sheds, right?
“Of note, only one case report of transmission from vaccine-associated measles has been identified.”
Murti et al. on Case of vaccine-associated measles five weeks post-immunisation, British Columbia, Canada, October 2013
That child got measles about 5 weeks after she was vaccinated in the middle of a measles outbreak. Because she had no links to the other cases and she tested positive for vaccine-strain measles, it is thought that she had MMR vaccine-associated measles, which is extremely rare.
Shedding Light on Measles Outbreaks in Daycare
MMR shedding is not causing outbreaks of measles – or rubella and mumps, for that matter.
If shedding from the MMR, by any method, got kids sick, then why aren’t there even more cases of measles?
When a case of measles does pop up though, it isn’t because of shedding, it is typically because someone who wasn’t vaccinated traveled out of the country, got measles, and brought it back home, exposing others.
What to Know About MMR and Shedding
Measles outbreaks are not caused by shedding from the MMR vaccine.
Answers To Frequently Asked Questions About Immunizations
Not surprisingly, many parents have the same questions about immunizations and they want answers to reassure themselves that they are doing the right thing for their kids by getting them vaccinated and protected.
They also push the myth that more vaccinated than unvaccinated kids get sick in most outbreaks.
Vaccinated vs Unvaccinated in an Outbreak
So are outbreaks usually caused by kids who have been vaccinated?
No, of course not.
Do we sometimes see more vaccinated than unvaccinated kids in some of these outbreaks?
Yes, sometimes we do.
Yes, we sometimes see more vaccinated than unvaccinated kids in an outbreak.
How can that be if vaccines work?
It is actually very easy to understand once you learn a little math and a little more epidemiology.
Basically, it is because while vaccines work, they don’t work 100% of the time, and more importantly, there are way more vaccinated kids around than unvaccinated kids.
The Mathematics of Disease Outbreaks
That means that you need to understand that more than the absolute number of vaccinated and unvaccinated people that got sick in an outbreak, you really want to know the percentages of vaccinated vs unvaccinated kids who got sick.
For example, in a school with 1,000 kids, you might be very surprised if six kids got a vaccine preventable disease, and three of them were vaccinated, leaving three unvaccinated.
Does that really mean that equal amounts of vaccinated and unvaccinated kids got sick?
I guess technically, but in the practical sense, it only would if half of the kids in the school were unvaccinated. Now unless they go to a Waldorf school, it is much more likely that over 90 to 95% of the kids were vaccinated, in which case, a much higher percentage of unvaccinated kids got sick.
Before we use a real world example, some terms to understand include:
attack rate – how many people will get sick when exposed to a disease
basic reproductive number or Ro – different for each disease, Ro basically tells you just how contagious a disease is and ranges from about 1.5 for flu, 8 for chicken pox, and 15 for measles
vaccine coverage – how many people are vaccinated
vaccine efficacy – how well a vaccine works
You also need to know some formulas:
attack rate = new cases/total in group
vaccine coverage rate = number of people who are fully vaccinated / number of people who are eligible to be vaccinated
vaccine effectiveness = (attack rate in unvaccinated group – attack rate in vaccinated group) / attack rate in unvaccinated group x 100
Unfortunately, it is often hard to use these formulas in most outbreaks.
For one thing, it is hard to get accurate information on the vaccination status of all of the people in the outbreak. In addition to those who are confirmed to be vaccinated or unvaccinated, there is often a large number who’s vaccination status is unknown. And even if you know the vaccination status of everyone in the outbreak, it can be even harder to get the vaccine coverage rate or a neighborhood or city.
For example, with measles, it is typically an unvaccinated person who travels out of the country, returns home after they have been exposed but are still in their incubation period, and then exposes others once they get sick. And the great majority of folks in these measles outbreaks are unvaccinated.
Some examples of these outbreaks include:
the 2014 Ohio measles outbreak that started with two unvaccinated Amish men getting measles in the Philippines while on a missionary trip and ended up with at least 388 cases before it was over, almost all unvaccinated
a 2013 North Carolina measles outbreak with 22 cases started after an unvaccinated traveler had returned from India
an outbreak of measles in New York, in 2013, with at least 58 cases, tarted with an intentionally unvaccinated teen returning from a trip to London
a 2011 outbreak of measles in Minnesota, when an unvaccinated child traveled out of the country, developed measles, and returned to his undervaccinated community, causing the state’s largest measles outbreak in 20 years
But what about mumps and pertussis?
Those outbreaks are all among vaccinated kids, right?
In one of the biggest mumps outbreak, in Arkansas, only 71% of people were up-to-date on their vaccines!
And keep in mind that while we do know that there are issues with waning immunity with some vaccines, you are still much more likely to become infected and get others sick if you are not vaccinated. And you will likely have a much more severe disease.
A 2013 pertussis outbreak in Florida is a good example that even with all the bad press it gets, the DTaP and Tdap vaccines work too. This outbreak was started by an unvaccinated child at a charter school with high rates of unvaccinated kids. About 30% of unvaccinated kids got sick, while there was only one case “in a person who reported having received any vaccination against pertussis.”
In another 2013 pertussis outbreak in Florida, this time in a preschool, although most of the kids were vaccinated, the outbreak started with “a 1-year-old vaccine-exempt preschool student.” And the classroom with the highest attack rate, was “one in which a teacher with a laboratory-confirmed case of pertussis who had not received a Tdap booster vaccination, worked throughout her illness.”
In outbreak after outbreak, we see the same thing, sometimes with deadly consequences – an unvaccinated child or adult triggers an outbreak and then a lot of unvaccinated folks get sick. Unfortunately, others get caught up in these outbreaks too, including those too young to be vaccinated, those who can’t be vaccinated because of true medical exemptions, and those whose vaccines may not have worked as well as we would have liked.
My intentionally unvaccinated kids don’t put your kids at risk. – Of course they do, because some kids are too young to be vaccinated or fully vaccinated, some kids can’t be vaccinated, including those with immune system problems, and vaccines don’t work 100% of the time.
Vaccines do cause autism. It’s the MMR vaccine. – Of all the competing theories of how vaccines are associated with autism (even though they aren’t), Wakefield‘s theory that it is the combined MMR vaccine was the first.
Recently vaccinated kids shed virus for weeks or months and can infect unvaccinated kids. – While shedding is real for some live vaccines, like oral polio and rotavirus, it is rarely a problem.
Vaccines don’t even work. – While some folks are worried about risks and side effects, others don’t even believe that vaccines work – ever. That’s understandable though, as it explains how they deal with the cognitive dissonance of leaving their kids unprotected from potentially life-threatening vaccine-preventable diseases. So instead of vaccines eradicating or controlling diseases, they come up with theories about improved sanitation and better nutrition doing all of the work. But of course, we know that vaccines work.
It’s good to get measles and other vaccine-preventable diseases. – While some people think that getting measles and polio was once a welcome rite of passage for kids, they seem to forget that vaccine-preventable diseases are life-threatening and can leave survivors with serious disabilities.
The shingles vaccine causes shingles. – The shingles vaccine won’t cause you to develop shingles, but if you got it and never had chicken pox, then like the chicken pox vaccine, it is thought that the shingles vaccine could theoretically cause a latent infection that reactivates = shingles.
Vaccines do cause autism. It’s thimerosal. – Vaccines are not associated with autism.
Getting too many vaccines too soon can overwhelm an infant’s immature immune system. Not true. Considering all of the germs that they are challenged with on a daily basis, it is easy to see that an infant’s immune system can handle all of the vaccines on the immunization and much more.
Package inserts for vaccines admit that they cause autism. – While Tripedia, a DTaP vaccine that was discontinued in 2011, did list autism in the adverse reactions section part of the package insert, it also stated that “it is not always possible to reliably estimate their frequencies or to establish a causal relationship.”
Big Pharma, or the pharmaceutical industry, is the one making all of the decisions about vaccines, including what goes in them, when you should get them, and deciding if they are really safe. – Of course there is no world-wide conspiracy about vaccines led by the pharmaceutical industry that involves doctors, health departments, the CDC, and the WHO, etc.
Antifreeze is a toxic ingredient in vaccines. – Antifreeze (ethylene glycol) is not, and has never been an ingredient in vaccines. Some vaccines do contain a similar sounding ingredient, 2-phenoxyethanol, but it isn’t antifreeze. Saying that some vaccines contain an ingredient that sounds like antifreeze isn’t as scary though.
Vaccines contain aborted fetal tissue. – While some vaccines are made with fetal embryo fibroblast cells from cell lines that are derived (the original cells have been copied over and over again) from two electively terminated pregnancies in the 1960s, the cells are removed from the final vaccine and no aborted fetal tissue is in any vaccine.
Many people don’t vaccinate. – There is a very vocal minority of people who do their best to push misinformation and conspiracy theories about vaccines and vaccine dangers, but except for pockets of susceptibles and clusters of unvaccinated kids and adults, most people are vaccinated.
The CDC says that you should stop breastfeeding to boost vaccine efficacy. – They have never said that. Neither has the WHO or any other group of experts. This myth about breastfeeding relates to a study done that suggested that delaying breastfeeding for an hour after getting the rotavirus vaccine might help it work better in developing countries.
Vaccines aren’t tested. – Vaccines are well tested for both safety and efficacy before they are approved and are added to the immunization schedule.
Herd immunity isn’t real. – Understanding just how wrong anti-vaccine folks are about herd immunity will help you go a long way towards understanding how they get most things about vaccines wrong. Herd immunity from vaccines is real.
Vaccines are contaminated with brain-eating ameobas. – Viera Scheibner is a micropaleontologist who claims that that it is ‘well-established’ that vaccines are contaminated with amoebas. They aren’t.
I have a link arsenal from Pubmed that show vaccines are dangerous. – PubMed is simply an index of articles in medical journals. Any medical journals, even they predatory, pay to publish medical journals. Being in Pubmed doesn’t mean that it is a good study. And cherry picking articles and abstracts from Pubmed doesn’t mean that you have done your research about vaccines or that you have found any proof that vaccines aren’t safe. It probably just means that you need to do a little more research.
The vaccine schedule has ballooned since 1983 and kids now get too many shots! – While the vaccine schedule has certainly grown over time, that is simply because kids today are protected from many more diseases. While kids got fewer vaccines in 1983, that was also the pre-vaccine era for Hib, hepatitis B, pneumococcal disease, meningococcal disease, rotavirus, hepatitis A, HPV, and chicken pox, etc.
Package inserts for vaccines admit that they cause SIDS. – Tripedia, a DTaP vaccine that was discontinued in 2011, does list SIDS in the adverse reactions section part of the package insert, but also states that “it is not always possible to reliably estimate their frequencies or to establish a causal relationship.”
The US has higher infant mortality rates than other industrialized countries because we give more vaccines. – Higher infant mortality rate in the US than some other industrialized countries are thought to be because we use different methods to calculate the infant mortality rate. They are also at the lowest level ever.
MSG is a toxic ingredient in vaccines. – MSG is an ingredient in some vaccines, but it is safe and not toxic.
Since adults don’t get vaccines or boosters, there can’t be herd immunity. – Most adults either already have natural immunity or have already been vaccinated, so this isn’t true. There are actually very few booster shots that adults need, but seniors do need a few extra vaccines.
Sick people can just stay home, so it doesn’t matter if they are vaccinated. – That’s kind of how quarantines work, but the main problem with this theory is that with many diseases, including some that are the most contagious, you can actually be contagious even before you show symptoms and you know you are sick. That’s why they often talk about people being at school, on the train, shopping at Walmart, or even at the beach when they have measles and have exposed others in an outbreak.
The media just scares people about outbreaks. – The media, with their vaccine scare stories, did once influence a lot of parents about vaccines, but it was more to make them afraid to get their kids vaccinated and protected. Alerting people of an outbreak in their area isn’t a scare tactic or hype. It is one of the ways to help control outbreaks, so that folks know when a disease is present in their community.
There is no Pharma liability. You can’t sue if a child is injured by a vaccine. – You can sue, you just have to go through Vaccine Court first.
Many religions are against vaccines. – Very few religions actually object to immunizations, which makes it very surprising how many folks get religious vaccine exemptions.
Measles and other vaccine preventable diseases aren’t that serious anymore. – They, of course, can still be life-threatening, even in this day of modern medicine.
Over 99% of vaccine side effects from vaccines are not reported by doctors to VAERS. – That’s not really true. Although most common side effects probably are underreported, more moderate and serious side effects are reported. For example, one study found that while a rash after measles, a known mild, side effect, was not commonly reported, vaccine-associated polio was often reported to VAERS. It is also imported to keep in mind that VAERS isn’t the only way that the safety of vaccines is monitored.
Many experts are against vaccines. – The so-called experts of the anti-vaccine movement are mostly doctors who are practicing way out of their field of expertise, including many who are not medical doctors, or whose ideas are not supported by the great majority of real experts on vaccines, infectious disease, and immunology.
Vaccinated kids cause most outbreaks. – Not true. Although vaccines don’t always work 100% of the time and so vaccinated kids sometimes get caught up in outbreaks, they are not the cause of most outbreaks.
Infants have an immature immune system and are too young to be vaccinated. – Not true. Although a baby’s immune system is immature, as compared to older kids and adults, vaccines work well to help protect them as their immune system continues to develop and mature.
The chicken pox vaccine has caused an epidemic of shingles. – Not true. It has been shown that the rise in shingles cases started before we started routinely giving chicken pox vaccines, did not continue to increase after we started routinely giving chicken pox vaccines, and also increased in countries that don’t give the chicken pox vaccines.
The United States gives more vaccines than any other country. – While there would be nothing wrong with that, as it would mean we were protecting our kids from more vaccine-preventable diseases, if you take any time to look at the immunization schedules from other countries, you can see it isn’t true.
Pediatricians can get up to $3 million in bonuses for vaccinating kids. – Pediatricians are not getting big bonuses, bribes, or kickbacks to vaccinate kids.
Glyphosate is contaminating our vaccines and will help make 50% kids autistic by 2025. – Glyphosate is not in vaccines and Stephanie Seneff‘s theory that 1/2 of kids will be autistic in 8 years doesn’t make much sense either.
Formaldehyde is a toxic ingredient in vaccines. – While formaldehyde is an ingredient in vaccines, it is also naturally found in all of our bodies and in some foods. The formaldehyde in vaccines is not toxic.
Vaccines aren’t tested together. – Yes, they are. Pediarix (combo vaccine with DTaP, hepB, and IPV) was tested with Hib and Prevnar and the hepatitis A vaccine was tested together with DTaP, IPV, Hib, and hepatitis B. Most vaccination combinations have been tested together, including the flu shot.
I’m not anti-vaccine, I’m pro-safe vaccine. – You can call yourself whatever you want, either pro-safe vaccine or pro-vaccine choice, but if you push anti-vaccine propaganda, then you are anti-vaccine.
$3.5 billion in vaccine court payouts prove that vaccine injuries are real. – No one says that vaccines are 100% safe or that vaccine injuries aren’t real. It is also important to keep in mind that the $3.5 billion in vaccine court payouts have been since 1988, during which billions of doses of vaccines have been given.
Vaccines cause resistance in viruses and bacteria. – Not true. Vaccines are not causing an increase in vaccine-resistant bacteria or viruses and can actually help us fight the growing problem of antibiotic resistant bacteria.
Unvaccinated kids are healthier. – A large study has shown that unvaccinated kids are not healthier than those who are vaccinated, they just get more vaccine-preventable diseases.
People never used to worry about measles. – A Brady Bunch episode about measles doesn’t mean that people weren’t worried about measles in the old days. There are plenty of newspaper headlines describing how measles epidemic once closed entire school districts for weeks at a time. When a measles epidemic hit New York City in 1951, a headline on the front page of the New York Times read “City in Grip of Measles Epidemic; Unusually Severe Siege Forecast.” And remember when Lassie had to save Timmy when he had measles? Sounds like they were worried…
Epigenetics explains many vaccine injuries. – No, it doesn’t.
Doctors don’t learn anything about vaccines. – Doctors learn a lot about vaccines and vaccine-preventable disease. What they do need to learn more about are the latest anti-vaccine talking points, so that they can readily address your concerns about vaccines and things that you might have read or heard that have scared you about vaccines.
The American Academy of Pediatrics “recommends that parents use the availability of HPV vaccines to usher in a discussion on human sexuality in a way consistent with their culture and values at a time when they determine their child is ready to receive that information.” – It’s a fringe group of pediatricians, the American College of Pediatricians who said this, not the AAP, who recommends that all kids get vaccinated and protected with the HPV vaccines.
Vaccines are made for adults, not kids. – Vaccines are made for both kids and adults. Some vaccines even have different formulations for kids than for adults, including hepatitis A, hepatitis B, and flu shots, etc. And think about how the DTaP (kids) and Tdap (teens and adults) shots are different, but protect against the same diseases. But vaccines work locally, where the shot was given, which is why it doesn’t really matter that kids or adults of different sizes get the same dose.
The HPV vaccine just encourages kids to have sex. – Studies have confirmed that HPV vaccines are safe and they don’t encourage kids to unprotected sex, one of many HPV vaccine myths.
Aluminum replaced thimerosal as the latest toxic ingredient in vaccines. – Aluminum in vaccines is not toxic and as an adjuvant, it did not replace the thimerosal, a preservative, in any vaccines.
Hepatitis B is a STD vaccine, so newborn babies don’t need it. – Tragically, many infants still get perinatal hepatitis B infections because of missed opportunities to get vaccinated and when they are exposed in non-high risk situations. Don’t skip your baby’s hepatitis B shot.
Correlation equals causation. – Many people think that their child is vaccine injured because they showed symptoms right around the time they received a vaccine. They correlate getting the vaccine with causing the vaccine injury. The correct phrase isn’t correlation equals causation though, it is “correlation does not imply causation.“ Just because two things seem to be related by time doesn’t mean that one caused the other.
SV40 contamination of vaccines causes cancer. – While the SV40 virus did contaminate some early vaccines, it has been shown that this contamination did not cause cancer.
Dr. Julie Gerberding, the first woman to lead the CDC, admitted that vaccines cause autism during an interview with Sanjay Gupta on CNN. – While discussing the Hannah Polling decision, Dr. Julie Gerberding did not say that vaccines can cause autism. She even went out of her way to mention all of the studies that “have concluded that there really is no association between vaccines and autism.”
Vaccines don’t work to get rid of any diseases. They just make the diseases disappear by changing their names. – This has to be one of the silliest myths about vaccines. Yes, some folks believe that smallpox wasn’t eradicated. It was instead renamed to monkeypox. Polio became acute flaccid paralysis. And measles became roseola. Of course, that didn’t happen because vaccines do work.
The first deaf Miss America suffered a vaccine injury. – Not true. While they initially blamed her being deaf on the DTP vaccine, it turns out that she had a reaction to the antibiotic Gentamycin that she was receiving for a Hib infection, a now vaccine-preventable disease.
Diane Harper was a lead researcher for the HPV vaccine who came out against the HPV vaccines. – Diane Harper‘s comments about the HPV vaccine have been overblown and mischaracterized. She supports the HPV vaccines and believes that they are safe.
Vaccines don’t work against pertactin-negative pertussis bacteria. – While we are finding more pertactin-negative pertussis bacteria, this doesn’t seem to be why we are seeing more pertussis or whooping cough. Pertussis vaccines work against other components of the pertussis bacteria besides pertactin and pertussis vaccines continue to be effective against pertactin-negative Bordetella pertussis bacteria.
There are graphs and charts that prove that vaccines didn’t save us and that vaccines don’t work – Those mortality graphs are pure propaganda and do not show how cases of vaccine preventable diseases (morbidity) were not affected by overall improvements in mortality rates in the early 20th century (a lot of people still got sick even as more of them survived) or how the effects of improved sanitation, nutrition, and health care peaked by the 1940s (for example, they use death rates instead of just absolute numbers of deaths to hide the fact that measles killed about 400 people each year in 1960). Vaccines work.
Johns Hopkins warns cancer patients to avoid children who were recently vaccinated. – They did once, but Johns Hopkins and other hospitals updated their instructions as new information became available. Hospitals no longer warn patients about restricting exposure to people who have recently been vaccinated.
Andrew Wakefield was proven right. – Wakefield has not been proven right. Studies have never confirmed his findings. He is still not allowed to practice medicine in the UK.
The shocking revelations of the CDC Whistleblower proves that vaccines cause autism. – What was supposed to be the biggest anti-vaccine conspiracy story of all time, the CDC Whistleblower, must have been the biggest let down for the anti-vaccine movement. He didn’t really blow the whistle on anything or anyone and didn’t even appear in Vaxxed, the CDC Whistleblower movie! While being secretly recorded, he basically complained about the way his coauthors of a study on vaccines and autism dealt with some data that he felt was statistically significant.
The Leicester Method proves that good sanitation and quarantines – not the smallpox vaccine – eradicated smallpox. – In addition to quarantines, they used vaccines in Leicester. They just didn’t use universal vaccination. They used ring vaccination – making sure all of the contacts of the person with smallpox got a smallpox vaccine. The Leicester Method of dealing with smallpox does not support the idea that smallpox was eradicated solely with good sanitation and quarantining folks with smallpox.
That vaccines have been legally called unavoidably unsafe means that they are dangerous. – Not true.
Vaccinating a child is like taking a child out of their perfectly functioning carseat and strapping them into a seat with dental floss. – Actually, the proper analogy would be that vaccinating a child is like protecting them with an age appropriate car seat. Skipping or delaying your child’s vaccines is like driving them around without a car seat or seat belts, so that they are unprotected if you get in a car accident.
The HPV vaccine isn’t safe, isn’t even necessary, and is probably the most dangerous vaccine every made. – Of course this is not true. Fortunately, more and more parents are coming to understand that the over-the-top anti-vaccine rhetoric about the HPV vaccine isn’t true. The HPV vaccines are safe and necessary and they work to prevent cancer.
Parents are losing their choice about vaccines and are being forced to vaccinate their kids. – While slogans about choice are catchy, new vaccine laws and mandates do not force anyone to get vaccinated.
Vaccines cause ADHD. – Yes, you can add ADHD to the long list of so-called vaccine-induced diseases, but like the others, it isn’t true. Vaccines do not cause ADHD.
Polio epidemics were caused by spraying of the pesticide DDT. – The only connection between DDT and polio is that some folks were so scared of polio, that once an outbreak came to town, because they didn’t know what caused it yet, they sprayed with DDT thinking it might be spread by mosquitoes. So polio first and then DDT spraying.
You should skip or delay vaccinating your premature baby. – Except in some situations when preterm babies weigh less than 2000g and mom is known to be hepatitis B negative, your preterm baby should be vaccinated according to the standard immunization schedule.
There are no double-blind, placebo-controlled randomized clinical trials for vaccines. – Placebos are used in many vaccine trials and there are many double-blind, placebo-controlled randomized clinical trials for vaccines.
Homeopathic vaccines are a safe and effective alternative to real vaccines. – While they might not cause many side effects, homeopathic vaccines or nosodes aren’t going to do much else either. They certainly aren’t going to protect your child from any vaccine-preventable diseases.
You should follow a Paleo vaccine schedule. – Like other non-standard, parent-selected, delayed protection vaccine schedules, the Paleo vaccine schedule is a made-up alternative to the standard immunization schedule and will leave your kids unprotected from vaccine-preventative diseases.
People who are anti-vaccine don’t hurt autistic families. – While I’m sure they tell themselves that, in addition to pushing the idea that autistic kids are damaged by vaccines, there are many other ways that the anti-vaccine movement hurts autistic families.
Vegans don’t vaccinate their kids. – While there are few vegan vaccines, most vegans do indeed vaccinate their kids.
The measles vaccine doesn’t protect against all measles strains. – All currently used measles containing vaccines, including the MMR vaccine, do actually protect against all measles strains. There is only one main type of measles virus, despite the many small changes in the virus that can help us identify different strains and genotypes.
There are over 100 vaccine/autism research papers that prove that vaccines cause autism. – No matter how high the count of research papers gets to, they still don’t support a link between vaccines and autism.
The anti-vaccine movement is supported by science and research. – The beliefs of the anti-vaccine movement, from germ theory denialism to ideas about detoxing and chemtrails, are only supported by pseudoscience and conspiracy theories.
A tetanus shot won’t help after you have already been cut, stabbed, or bitten. – Well, if you are fully vaccinated, you might not even need a tetanus shot after a cut, because you are already protected. If you are unvaccinated or if it has been more than 5 years since your last shot, a tetanus shot and tetanus immune globulin will indeed work to protect against tetanus spores germinating, growing and producing their exotoxin that produces the symptoms of tetanus.
Immigrants and refugees are spreading disease in the United States and are putting us at risk for a new pandemic disease outbreak. – Immigrants and refugees are not spreading disease in the United States.
Parents have to pay the Vaccine Excise Tax to fund the Vaccine Injury Compensation Trust Fund. – The Vaccine Excise Tax is actually a tax that the U.S. Department of the Treasury collects from vaccine manufacturers.
Pediatricians are just vaccine pushers. – If that were true, then how come pediatricians don’t push all of the FDA approved vaccines on kids, such as the adenovirus vaccine, BCG vaccine, typhoid vaccine, or yellow fever vaccine?
Chiropractors aren’t anti-vaccine. – Maybe some aren’t, but most chiropractors seem to believe in germ theory denialism, push anti-vaccine talking points, and don’t vaccinate their own kids.
There are 300 new vaccines in the pipeline. – While new vaccines are always being researched and developed, we are not getting 300 new vaccines anytime soon. At least 1/3 of those are therapeutic vaccines for cancer. And 1/4 are for the same four infectious diseases – HIV, flu, RSV, and Ebola. So no, we aren’t getting 300 new vaccines.
Breastfeeding is better than vaccines at preventing infections. – While breastfeeding is great and has a lot of benefits, including providing some passive immunity, it won’t protect your child from most vaccine-preventable diseases. Breastmilk contains IgA antibodies, and not the IgG antibodies that vaccines trigger in our bodies and which do cross the placenta and protect our babies for a short time. Breastmilk can help protect a child against some viruses and bacteria that cause diarrhea and respiratory infections, but it is not better than vaccines at preventing vaccine-preventable diseases.
Ingredients in vaccines are toxic because they are injected directly into a child’s bloodstream and aren’t ingested and filtered by the body’s natural defenses. – The ingested vs injected argument comes up a lot, but doesn’t make much sense. For one thing, vaccines aren’t injected into the bloodstream.
I used Google University to research vaccines, just like other medical professionals use google to look up medical information. – While it is true that many medical professionals are likely turning to the internet more than textbooks when they need to look something up, they are often using online medical textbooks or other reputable sites. They aren’t cherry picking information from sites that simply confirm their biases against vaccines.
Vaccines aren’t tested for use in pregnancy. – They are and pregnant women should get a seasonal flu vaccine and a Tdap vaccine each and every pregnancy.
DNA in vaccines can cause autism. – While highly fragmented (mostly destroyed) DNA has been found in some vaccines, it can’t cause harm.
The Amish don’t get autism. – The Amish do get autism. They also do vaccinate – sometimes. They also get vaccine-preventable diseases as we saw in the large Ohio measles outbreak of 2014.
Circulating vaccine-derived polio virus or cVDPV are outbreaks of polio that are actually caused by the polio vaccine.
Very rarely, the attenuated (weakened) virus in the oral polio vaccine can revert to a form that can cause the person who was vaccinated or their close contact to actually develop polio.
It should not be confused with VAPP or vaccine-associated paralytic polio. With VAPP, the original strain of attenuated vaccine virus reverts to a form that can cause polio, but it does spread from one person to another, so does not lead to outbreaks.
Fortunately, both VAPP and cVDPV are rare.
How rare? VAPP only occurs in about 1 in every 1.27 million children receiving their first dose of OPV.
And according to the WHO, there had only been about 24 outbreaks of cVDPV over the past 10 years. Tragically, this has resulted in at least 750 cases of paralytic polio in 21 countries.
A new outbreak of cVDPV in Syria adds to those numbers though.
After being polio free for 15 years, since 1999, Syria began having cases of wild type polio again in 2013 (35 cases) and 2014 (1 case). Those polio cases and the emergence of an outbreak of cVDPV2 (there are three strains of polio virus – this outbreak was caused by the type-2 strain) highlight the effects of years of poor immunization rates because of war.
While there are many challenges to getting kids vaccinated in Syria, up to 355 vaccination teams with 61 supervisors will be working out of five vaccine distribution centers to vaccinate 328,000 children to control the outbreak and get kids vaccinated.
Circulating Vaccine-Derived Polio Virus
Just like wild type polio, we can stop cVDPV by increasing vaccination rates and increasing access to improved sanitation facilities.
Although anti-vaccine folks routinely cry wolf about shedding, the oral polio vaccine really does shed – in the stool of people who have been recently vaccinated. You can then be exposed to the attenuated polio vaccine virus (which can help give immunity to others in the community by passive immunization) or a strain of cVDPV (which can, unfortunately, help give others, especially if they are not vaccinated, paralytic polio) if they are exposed to open sewage or can not practice proper hygiene, etc.
Can’t we just stop using the live, oral polio vaccine?
Although a serious side effect of the vaccine, the vaccine’s benefits clearly outweigh the risk of both VAPP and cVDPV while polio is endemic (lots of cases) in a region, after all, without the vaccine, hundreds of thousands of children would get polio and would be paralyzed.
In polio-free countries, the risks of VAPP and cVDPV becomes greater than the risk of polio though, and they move to the inactivated polio vaccine. That helps prevent a situation in which the polio vaccines actually causes more cases of polio than wild type polio viruses.
Eventually, all countries will move to the IPV vaccine as we move closer to polio eradication. We came one step closer to that point in April 2016 when all countries that were still using the oral polio vaccine switched from trivalent OPV (three strains) to bivalent OPV (two strains) for their routine immunization programs. This could eliminate up to 90% of cases of cVDPV (most are caused by the type-2 strain which is not in bOPV)!
What To Know About cVDPV
Circulating vaccine-derived polio virus outbreaks are a rare side effect of the oral polio vaccine.
their child is on antibiotics – having a mild illness is not usually a good reason to skip or delay getting vaccines
their child had an allergic reaction to a vaccine – a severe, anaphylactic reaction to one vaccine or vaccine ingredient wouldn’t mean that your child couldn’t or shouldn’t get all or most of the others
a doctor wrote them a medical exemption – there are actually very few true contraindications to getting vaccinated and a permanent exemption to all vaccines would be extremely rare, which casts doubt on the ever growing rate of medical exemptions in many areas
they are Muslim – most Muslims vaccinate their kids and most Islamic countries have very good immunization rates.
someone at home is immunocompromised – since we stopped giving the oral polio vaccine, shedding from vaccines is not a big concern and contacts of those who are immunocompromised are usually encouraged to get vaccinated
they are Buddhist – most Buddhists vaccinate their kids – the Dalai Lama even led an oral polio vaccination drive recently and Buddhist countries have very good immunization rates.
someone in their family had a vaccine reaction – a family history of a vaccine reaction is not a good reason to skip or delay getting vaccinated, as it has not been shown to increase your own child’s risk of a reaction. And yes, this has even been shown for siblings of autistic children, which makes sense, since vaccines don’t cause autism.
What about other religions?
Whether you are Hindu, non-Catholic Christians, Amish, or Jehovah’s Witnesses, etc., remember that all major religions believe in vaccines. Of course, the Amish are a little more selective of when and which vaccines they will get, but as we saw in the Ohio measles outbreak, they do get vaccinated.
On the other hand, Christian Scientists don’t vaccinate, along with some small Christian churches that believe in faith healing and avoid modern medical care.
Still, most people understand why it is important to vaccinate their kids.
What to Know About These Reasons to Not Vaccinate Your Kids
What do you think about these reasons to not vaccinate your kids? Since they aren’t really absolute reasons to not get vaccinated, are you ready to get your kids vaccinated now?
Although vaccine shedding is a concern with some live vaccines, like the oral polio vaccine and the small pox vaccine, it is important to keep in mind that neither has been used in the United States for some time now.
Hospitals no longer warn patients about restricting exposure to people who have recently been vaccinated.
Were websites scrubbed of information about shedding as part of some conspiracy?
Of course not.
They were simply updated to keep up with the latest guidelines.
Can Immunocompromised Patients Have Visitors?
These guidelines about kids with cancer aren’t that new though.
As far back as 2001, an article in the journal Pediatrics & Child Health, “Practical vaccination guidelines for children with cancer,” recommended that household contacts of immunosuppressed children should receive:
all routine, age-appropriate vaccines, including DTaP, IPV, Hib, MMR, and Tdap, and that no special precautions are necessary because transmission of disease from these vaccines does not occur.
the varicella vaccine and that even in the event of a vaccine-associated vesicular rash, the transmission risk is low and the consequences of infection are limited by the attenuated nature of the vaccine virus.
receive either the inactivated influenza vaccine or live attenuated influenza vaccine, giving preference to the inactivated influenza vaccine only if the immunosuppressed person is a hematopoietic stem cell transplant (HSCT) recipient in a protected environment.
So hospitals should no longer be warning patients about restricting exposure to people who have recently been vaccinated.
In fact, the latest guidelines from the Immune Deficiency Foundation Advisory Committee state that except for the live oral poliovirus vaccine, close contacts can receive other standard vaccines because viral shedding is unlikely and these pose little risk of infection to a subject with compromised immunity.
The Immune Deficiency Foundation also warns that, “The increased risk of disease in the pediatric population, in part because of increasing rates of vaccine refusal and in some circumstances more rapid loss of immunity, increases potential exposure of immunodeficient children.”
In other words, they are concerned about the risk of disease from intentionally unvaccinated kids and not from those who were recently vaccinated!
So, what about visitors?
“Tell friends and family who are sick not to visit. It may be a good idea to have visitors call you first.”
The Johns Hopkins Hospital Patient Information Guide
Although you can’t prevent every cough and cold that might keep you from visiting a friend or family member who is being treated for cancer or has another immune system problem, keeping up to date on all vaccines can help to make sure that you don’t spread a vaccine-preventable disease, like measles or chickenpox, to them.
What To Know About The Johns Hopkins Vaccine Warning
Not only is Johns Hopkins Medical Center not telling cancer patients to avoid contact with children who recently received vaccines, they have gone out of their way to correct that misinformation from anti-vaccine websites.
Some folks haven’t gotten the message though and continue to push the idea that Johns Hopkins and other Hospitals warn cancer patients to avoid contact with recently vaccinated children.
