13 vaccines, including 5 doses of DTaP, 4 doses of IPV (polio), 3 or 4 doses of hepatitis B, 3 or 4 doses of Hib (the number of doses depends on the vaccine brand used), 4 doses of Prevnar, 2 or 3 doses of rotavirus (the number of doses depends on the vaccine brand used), 2 doses of MMR, 2 doses of Varivax (chicken pox), 2 doses of hepatitis A, 1 doses of Tdap, 2 or 3 doses of HPV (the number of doses depends on the age you start the vaccine series), 2 doses of MCV4 (meningococcal vaccine), and yearly influenza vaccines
protection against 16 vaccine-preventable diseases, including diphtheria, tetanus, pertussis, measles, mumps, rubella, polio, chicken pox, pneumococcal disease, hepatitis A, hepatitis B, meningococcal disease, HPV, rotavirus, Hib, and flu
about 28 doses of those vaccines by age two years (with yearly flu shots)
about 35 doses of those vaccines by age five years (with yearly flu shots)
as few as 23 individual shots by age five years if your child is getting combination vaccines, like Pediarix or Pentacel and Kinrix or Quadracel and Proquad
about 54 doses of those vaccines by age 18 years, with a third of that coming from yearly flu vaccines
How do you get a number like 72?
You can boost your count to make it look scarier by counting the DTaP, MMR, and Tdap vaccines as three separate vaccines each, even though they aren’t available as individual vaccines anymore.
This trick of anti-vaccine math quickly turns these 8 shots into “24 doses.”
At age four years, when your preschooler routinely gets their DTaP, IPV, MMR, and chicken pox shots before starting kindergarten, how many vaccines or doses do you think they got? Two, because they got Kinrix or Quadracel (DTaP/IPV combo) and Proquad (MMR/chickenpox combo)? Four, because they got separate shots? Or Eight, because you think you should count each component of each vaccine separately?
Know that even if you do want to count them separately, it really just means that with those two or four shots, your child got protection against eight different vaccine-preventable diseases – diphtheria, tetanus, pertussis, polio, measles, mumps, rubella, and chicken pox.
So why would some people think that vaccines could actually cause meningitis?
Meningitis is listed as a possible adverse event in the package insert of some vaccines, but only in the section that includes spontaneously reported data from post-marketing experience, where it “may not be possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.”
Meningitis is typically caused by a virus, bacteria, parasite, or fungus, etc.
While a live virus vaccine might rarely be able to cause an infection, few of the meningitis vaccines are live virus vaccines. Prevnar, Hib and the meningococcal vaccines are all sub-unit vaccines. Since only a part of bacteria (antigens) is actually present in the vaccine, it is not possible for them to cause an infection.
What about the live virus vaccines, like MMR, chicken pox, and rotavirus?
Since these viral infections rarely cause meningitis, except for mumps, you wouldn’t expect the rare vaccine induced infection to cause meningitis either. A natural measles infection, for example, is more likely to cause encephalitis instead.
“…there is no evidence to link Jeryl Lynn mumps vaccine to aseptic meningitis.”
MMR Package Insert
What about the chicken pox vaccine? There is a case report of a vaccinated child who later developed shingles and meningitis, caused by vaccine strain chicken pox virus. He recovered fully and it is important to note that folks with natural chicken pox are thought to be even more likely to develop shingles, and they too can develop meningitis.
The bottom line is that if someone has meningitis, even if they were recently vaccinated, you shouldn’t be blaming the vaccines.
Like they do with VAERS reports, misusing package inserts is a common method that anti-vaccine folks use to scare parents away from vaccinating and protecting their kids.
What to Know About Meningitis and Vaccine Package Inserts
Although included in some vaccine package inserts, except for rare circumstances with some live virus vaccines, none actually claim that vaccines cause meningitis.
It is bad enough that folks in the anti-vaccine movement use propaganda to scare parents away from vaccinating and protecting their kids.
“The anti-vaccine argument is wrong in both the scientific and moral sense.”
Sarah Kurchak on Here’s How the Anti-Vaccination Movement Hurts Autistic People
Many people also think that the anti-vaccine message is anti-autism.
How the Anti-Vaccine Movement Takes Advantage of Dead Children and Their Parents
But just when you thought that they couldn’t go any lower, folks in the anti-vaccine movement find new ways to demonstrate their lacks of morals.
As a physician, I assure you this story isn’t believable at any level. In my opinion, the “health officials” are conjuring meningitis fairy tales about an “unvaccinated” boogeyman to cover for the much more probable cause of this child’s death: VACCINES.
The much more likely cause is right in front of us: “The child had just received his 4-month-old vaccinations two days beforehand.”
“Notice that THREE of the vaccines given at 4 months are for organisms capable of invading the brain and causing MENINGITIS. Rotavirus is a live virus vaccine capable of shedding from recently vaccinated children. The vaccine pre-clinical trials lacked placebo controls and were associated with infant deaths.
It doesn’t take my medical degree to understand how flimsy are the claims in this story.”
While rotavirus is a live virus vaccine, rotavirus rarely causes central nervous system disease. And he died of bacterial meningitis. It shouldn’t take a medical degree to know that rotavirus is a virus, not a bacteria.
While two of the other vaccines routinely given at four months do actually protect you from meningitis, both Prevnar and Hib are sub-unit vaccines, so can’t actually cause disease. Unfortunately, at four months, he would have been only partially protected against Prevnar and Hib, having only received two of four dosages of those vaccines.
“They expect the general public to be ignorant of the fact that we can actually measure the presence of the meningitis causing organisms for which there are vaccines: Haemophilus influenzae, Pneumococcus, and Meningococcus. So, where are the tests that confirm the presence of one of these “vaccine preventable” organisms?! Where’s the spinal tap/CSF pathology report?
As hard as it is for a grieving family to conceive of an autopsy, I pray the family demands a confirmation of the farcical cause of death being contrived in this case.”
Has Jim Meehan heard of HIPAA?
Does he read any of the other messages when he is writing his own comments about this family?
Is Jim Meehan really a doctor? It shouldn’t take a medical degree to understand that carriers of a disease don’t usually have symptoms of the disease.
“Again, from the article: “Health care officials told Dempsey they BELIEVE an unvaccinated person was carrying meningitis and Killy happened to come into contact with that person.”
They “believe”…give me a break. It should have said, “they made-up a story to cover for the real cause.”
SECOND, people don’t walk around with meningitis. They lay in their beds in a dark room and writhe in pain.
THIRD, the likelihood that an unvaccinated individual was walking around with meningitis is vanishingly small. To even list that in the top 100 options of a differential diagnosis is pure fiction.
FOURTH, where is this hypothetical unvaccinated meningitis shedding “patient zero?” He or she would have been so obviously sick that there is no way new parents would not remember the likely suspect…unless the suspect never existed.”
In this case, with a meningococcal infection, which is what the infant is thought to have, about 10% of people are carriers, asymptomatically having the Neisseria meningitidis bacteria in their nose or throat.
In the United States, we have two types of meningococcal vaccines, neither of which is routinely given to infants:
Menactra and Menveo – meningococcal conjugate vaccines that protect against serogroups A, C, W, Y and first given when kids are 11 to 12 years old, with a booster at age 16 years.
Bexsero and Trumenba – meningococcal conjugate vaccines that only protect against serogroup B and can be given to kids at increased risk and teens and young adults who want to reduce their risk of getting MenB disease
The only other possibility, since they mentioned that exposed people received antibiotics, would be the Hib bacteria.
“In the prevaccine era, Hib could be isolated from the nasopharynx of 0.5%–3% of normal infants and children but was not common in adults.”
CDC on the Epidemiology and Prevention of Vaccine-Preventable Diseases
Again, these carriers can be contagious, even though they don’t have any symptoms.
“It’s likely that these “health officials” are covering for the pharmaceutical/vaccine industry that pays them so well. It’s “health officials” like this that for decades have pretended that sudden unexplained infant death syndrome (SUIDS), not only has no explanation, but it couldn’t possibly be related to the injection of neurotoxic doses of aluminum into the bodies of tiny baby humans. They can ignore the clustering of infant deaths that occurs around the same times that CDC recommends multiple (5-13) vaccines at one visit, but I won’t.”
Why is a family that just lost their child getting harassed by anti-vaccine folks?
One clue is that Jim Meehan is pushing the idea that there is a Big Pharma conspiracy behind this child’s death.
And there are many anti-vaccine parenting groups that are helping spread his message around.
Of course, this isn’t the first time this has happened.
Anti-vaccine folks routinely hound parents who die of SIDS and shaken baby syndrome, working to convince them that vaccines caused their deaths.
There was a baboon study with the pertussis vaccine and it found that previously vaccinated baboons could develop asymptomatic carriage of the pertussis bacteria after they were intentionally infected.
Here is where it is important to note that an infection is different than a disease.
The example that many people are familiar with is tuberculosis. It is common to have a TB infection without any signs or symptoms and to not feel sick. The only reason we know that they have TB is because they had a positive TB test.
Unfortunately, about 5 to 10% of these people with TB infections can eventually develop TB disease, with coughing, weight loss, night sweats, fever, and chest pain, etc.
It is kind of the same with the baboons in the study. Twenty-four hours after two previously vaccinated baboons were inoculated with pertussis bacteria in the back of their nose and trachea, an unvaccinated baboon was put in each of their cages.
The vaccinated baboons continued to have pertussis bacteria in their noses, which the researchers had put there, for up to 35 days. And they were able to eventually pass the pertussis bacteria to the unvaccinated baboons in their cages. Vaccinated baboons also became infected or colonized after they were put in a cage with an intentionally infected unvaccinated baboon.
“…animals did not cough and showed no reduction of activity, loss of appetite, or other outward signs of disease.”
Warfel et al on Acellular pertussis vaccines protect against disease but fail to prevent infection and transmission in a nonhuman primate model
The vaccinated baboons were infected, but they never did develop symptoms of pertussis.
What Does The Baboon Study Mean?
One thing that is for sure – the baboon study found that the pertussis vaccines work. Only unvaccinated baboons got sick with pertussis.
Are vaccinated people becoming colonized and then getting others sick?
I guess it is possible, but we are not baboons in a cage with other baboons. How would we spread a respiratory disease, even if we did become colonized with the bacteria, if we don’t have symptoms?
It may explain part of our outbreaks though.
If vaccinated people do commonly become colonized with pertussis bacteria, then they might very well test positive for pertussis even though they don’t have symptomatic pertussis disease. So when they develop a cold or bronchitis and are found to have a positive pertussis test, then couldn’t that test just indicate that they have a pertussis infection and not disease, even though something else is actually causing their symptoms?
That’s kind of what the baboon study found. All of the baboons tested positive, but only the unvaccinated baboons had symptomatic pertussis disease.
“Baboons vaccinated with wP vaccines exhibit a level of protection that is intermediate between convalescent animals and aP-vaccinated animals. They exhibit no outwards signs of disease and are initially colonized to the same high level as aP-vaccinated animals but clear the infection more rapidly.”
Pinto et al on Pertussis disease and transmission and host responses: insights from the baboon model of pertussis.
It is interesting to note that the baboon study also found that baboons who had received whole cell pertussis vaccines also became carriers. They just didn’t stay carriers for as long as the baboons who got the newer acellular pertussis vaccine. But since they were still carriers, if asymptomatic transmission is such a big problem, wouldn’t it have been a big problem back in the day when everyone got whole cell pertussis vaccines?
“The baboon model pioneered by Warfel et al. is without question a game-changer, shedding light on the impact of vaccination on disease and infection. However, the view it affords is clearer with respect to immunity and pathology than with respect to transmission. We point out that the extrapolation of the possibility of transmission from vaccinated baboons in the laboratory to the probability of transmission from vaccinated humans in the population is unwarranted. More work is needed to elucidate the relative transmissibility of infections in vaccinated vs. unvaccinated hosts. The evidence adduced above suggests, however, that vaccination with aP must have a strong effect on transmission as well as disease.”
Matthieu Domenech de Cellès et al on Epidemiological evidence for herd immunity induced by acellular pertussis vaccines
Even the author of the baboon study has said that “We agree that these data should not be directly extrapolated to pertussis transmission in humans. Although baboons are >96% genetically similar to humans, there are likely differences in how the species respond to vaccination and infection. We also agree that aP-vaccinated infected people are likely less efficient at transmitting pertussis compared with unvaccinated infected people, although it is not clear to what extent.”
Others think that asymptomatic carriage of pertussis might behind a lot of our recent outbreaks. Or at least what helps them grow so large.
Still, it is important to remember that unvaccinated folks do play a role in these outbreaks too. In a pertussis outbreak at a Florida preschool, in which most kids were vaccinated, the outbreak was started by a vaccine-exempt toddler.
And we have seen this in many other areas and it has been confirmed by many studies. Whatever else is contributing to pertussis outbreaks, like waning immunity, they are also associated with vaccine refusal.
“Counties with higher exemption rates had higher rates of reported pertussis among exempted and vaccinated children when compared with the low-exemption counties.”
Imdad et al. on Religious exemptions for immunization and risk of pertussis in New York State, 2000-2011.
But what if the DTaP and Tdap vaccines do cause folks to be asymptomatic carriers?
Even if that is true, understand that these vaccines don’t actually infect you, making you a carrier. They just might not prevent you from becoming a carrier if you are exposed to someone else with pertussis. While that might be a good reason to develop a new and better pertussis vaccine, it certainly isn’t a reason to skip or delay your child’s vaccines now.
Remember that even with our current outbreaks, rates of pertussis were much higher in the pre-vaccine era.
What to Know About Vaccines and Asymptomatic Carriers of Pertussis
The role of asymptomatic carriers and pertussis is controversial, but it certainly isn’t a reason to skip or delay your child’s vaccines.
More on the Vaccines and Asymptomatic Carriers of Pertussis
Well, unlike most other vaccines, the meningococcal B vaccines are not thought to decrease nasal carriage of the meningococcal B bacteria. So if you are vaccinated and an asymptomatic carrier of the bacteria, you could theoretically spread it to someone else, as could someone who is unvaccinated.
Still, the MenB vaccines can protect you from getting actual meningococcal B disease, and if you don’t have meningococcemia or meningococcal meningitis, you won’t expose and spread it to someone else. That’s why the MenB vaccines are especially useful in outbreak situations.
Any others? After all, Dr. Bob did say that “most vaccines don’t prevent the spread of a disease.”
Vaccines That Don’t Prevent the Spread of a Disease
There are a few other examples of vaccines that don’t prevent the spread of a disease.
“I also warn them not to share their fears with their neighbors, because if too many people avoid the MMR, we’ll likely see the diseases increase significantly.”
Dr. Bob Sears in The Vaccine Book
Of course, any vaccine that is delayed or skipped won’t work to prevent the spread of a disease.
Just like they are seeing measles outbreaks and deaths now, because of low vaccination rates, in Ukraine there were 17,387 cases of diphtheria and 646 deaths from 1992 to 1997. Also high, were cases of measles (over 23,000 cases in 1993) and pertussis (almost 7,000 cases in 1993).
And because of waning immunity, vaccines don’t do as good a job of preventing the spread of pertussis and mumps as we would like. Still, that’s only when the vaccines don’t work, and even then, as Dr. Bob says, they do work to reduce the severity of symptoms. During recent mumps outbreaks, the rates of complications are far below historical levels. The same is true for pertussis.
We typically see the same thing with flu. Even when the flu vaccine isn’t a good match or isn’t as effective as we would like, it still has a lot of benefits, including reducing your risk of dying.
“IPV induces very low levels of immunity in the intestine. As a result, when a person immunized with IPV is infected with wild poliovirus, the virus can still multiply inside the intestines and be shed in the faeces, risking continued circulation.”
Inactivated poliovirus vaccine
Does the fact that IPV, the inactivated polio vaccine, can sometimes lead to infections and shedding mean that it doesn’t prevent infections?
Of course not!
“IPV triggers an excellent protective immune response in most people.”
Inactivated poliovirus vaccine
Most people vaccinated with IPV will be immune, won’t get wild polio, and so won’t be able to get anyone else sick.
“Vaccines reduce disease by direct protection of vaccinees and by indirect protection of nonimmune persons. Indirect protection depends on a reduction in infection transmission, and hence on protection (immunity) against infection, not just against disease. If a vaccine were to protect only against disease, and not at all against infection, then it would have no influence on infection transmission in the community and there would be no indirect protection (vaccination of one person would have no influence on any others in the community). It would be possible to reduce disease with such a vaccine but not to eradicate the infection.”
But because IPV doesn’t provide indirect protection, we still use OPV in parts of the world where polio is more of a problem.
Vaccines work. Even the few that don’t prevent the spread of infections, still help to reduce disease.
What’s the Difference Between Infections and Disease?
Wait, is there a difference between infection and disease?
Yes there is, something that Dr. Bob, who actually wrote a book about vaccines, seems to have overlooked.
An infection is simply the presence of a virus, bacteria, or other organism in your body.
A disease, on the other hand, is a virus or bacteria in your body causing signs and symptoms.
All vaccines work to prevent disease, or at least they do when you actually get vaccinated.
A very few don’t prevent infections and the spread of infections, but that is not a good reason to skip or delay your child’s vaccines. In fact, it is one of the reasons why it is important to have high vaccination rates! Even natural infections don’t always keep you from becoming asymptomatic carriers that can infected others. Many people who have natural typhoid (remember Typhoid Mary?) and hepatitis B infections go on to become chronic carriers without any symptoms, but still able to infect others.
If you understand that a few vaccines don’t prevent the spread of infections, then you should understand that you can’t hide in the herd and expect to be protected, even though most folks around you are vaccinated.
What to Know About Vaccines and the Spread of Disease
Despite what Dr. Bob says, almost all vaccines work to prevent the spread of disease and infections, at least they do when you get your kids vaccinated.
She even defends Andrew Wakefield and doesn’t believe that people died of measles once MMR vaccination rates went down after Wakefield’s study was published.
A Crazymother Visits Her Pediatrician to Talk About Vaccines
As someone who is mindful that language can promote stigmas and stereotypes, it is not a term that I chose.
It is the name of a parenting group.
Wait until you hear what this pediatrician has to say when a Crazymother informs her she will no longer be vaccinating!
“Ok, today is just a hepatitis vaccine.”
I have made the decision that I no longer want my kids to be vaccinated.
At all. So, I know that’s not what you want to hear.
“It isn’t. It scares me. It scares me a lot.”
I know. I hear that, but I also have to do what I feel is best.
“Is there a specific concern that you have?”
Oh, there is a lot of things.
“What are they?”
There’s a lot. I’m worried about a lot. I wasn’t planning on having this conversation today. I didn’t know he was getting a shot. I wasn’t prepared. I thought he coming in for a blood test today. There’s a lot of reached out and met a lot of other moms who just have a lot of really sad stories and I just kind of started doing my own research and I just don’t feel like it is best for my kids and … I’m very concerned for his health and him getting vaccinated with all of these problems that he already has isn’t going to benefit him right now so I may change my mind down the road.
That last paragraph says an awful lot about why some parents are choosing to delay or skip their children’s vaccines:
“So my job at every visit is to let you know what you are declining and what we’re trying to protect against. It’s also very important if you decide not to immunize to remember that he’s at risk for a lot of other things so if he gets a fever its going to mean something different to mean than a child who is fully immunized as a fever… so if you call us after hours and he has a fever, make sure you tell us, oh by the way, he isn’t immunized…”
How does it mean something different if a child is intentionally not vaccinated?
While a vaccine-preventable disease should be in the back of your mind for any kid if their symptoms fit the disease, since vaccines aren’t 100% effective, they move higher up your list of possibilities if you know the child is unvaccinated and unprotected.
“I also just want to tell you that there’s a very big difference between anecdotal evidence and population based evidence, so just because someone has a sad story doesn’t mean that what happened to them is truly related to the vaccine.”
Crazymothers – OMG, I can’t even with this… She said that children didn’t get the MMR and many died. That’s not true. If you look at the cases of measles after 1998 when the Lancet study was published the measles cases actually went down. Nobody died. Nobody has died in America for years and years from the measles. It is completely silly.
Measles cases went down?
“Between 2001 and 2013 there was a sharp rise in the number of UK measles cases, and three people died.”
Current measles risks in the UK and Europe
As most folks now, before Wakefield was stripped of his medical license, he practiced in the United Kingdom, and not surprisingly, that’s where we saw a big effect on MMR rates. They went down and measles cases went up.
But even as measles cases and deaths have gone down globally, measles outbreaks and measles deaths have been much worse in the rest of Europe.
Even in the United States, cases have gone way up since we hit a record low of 37 cases in 2004 and there have been deaths, with the last in 2015.
“Again, this was very contentious and you would not get consensus from all members of the group on this, but that is my feeling, that the, the risk of this particular syndrome developing is related to the combined vaccine, the MMR, rather than the single vaccines.”
It is amazing how many times you hear the phrase “that’s not true” in this video about things that are so easy to confirm as facts.
“Continue to give it some thought because to me vaccines are modern miracles and it scares me to death to have people not getting vaccinated… He’ll probably be okay, but that’s because I’ve vaccinated my kids the other day, so we’re protecting your kid… The more people who stop doing it, forget about it, it’s going to go back to the old days where people are dying all of the time.”
Crazymothers – There’s that herd immunity myth. She says that your kid is going to be okay because I’m doing the right thing. I’m vaccinating my child. And anybody who studies this knows that’s not true! Herd immunity is a myth. Go outside and talk to a 30-year-old, 40-year-old, 50-year-old, who hasn’t been recently vaccinated and you can clearly see, plain as day…
As far as I know, we have indoor plumbing, we have sewage systems, we have clean water, and we have access to whole foods, we have ways to supplement with vitamins and minerals, we have all of these amazing things and that is what actually brings disease rates down.
Proper sanitation, sewage systems, all of the modern things that we take for granted – that is what is actually bringing the disease down, because clearly, in under-developed countries, we still see the diseases rampant, right?
But herd immunity is disease specific, so when we talk about herd immunity for measles, it doesn’t matter if someone has immunity against hepatitis A or Hib. Also, some vaccines, like Hib and Prevnar, have indirect effects, protecting adults even though they aren’t vaccinated, because vaccinated kids are less likely to become infectious.
There is only clearly one modern thing that that anti-vaccine folks take for granted – vaccines.
My uncle got polio around 1950, in Brooklyn, just before the first polio vaccine was developed.
You know what?
They had indoor plumbing, sewage systems, clean water, whole foods, vitamins and minerals, and medicine – he was hospitalized for six months – yet many people still died of polio.
At that time, during the pre-vaccine era, many people also died of measles, tetanus, pertussis, chicken pox, and many other diseases that are now prevented with vaccines.
And unfortunately, many under-developed countries still don’t have proper sanitation, sewage systems, or good nutrition, but do you know what they also don’t have?
We are very close to eradicating polio all over the world. Only two countries, Afghanistan and Pakistan still have cases of wild polio today. And so far this year, there have only been 11 cases. Did every other country in the world suddenly get proper sanitation, sewage systems, and good nutrition? Is that why we are so close to eradicating polio?
Of course not. It’s the polio vaccine.
Vaccines work. Vaccines are safe and necessary. They have few risks and many benefits. You won’t learn any of that from the Crazymothers group and that’s likely why you have made the decision that you no longer want your kids to be vaccinated.
What to Know About Crazymothers Propaganda
Don’t let Crazymothers propaganda scare you away from vaccinating and protecting your kids.
It is not news that we have been seeing more cases of mumps in recent years.
It is also isn’t news that many of these folks are vaccinated.
“Long Beach has been hit with a mumps outbreak that is vaccine-resistant. According to health officials in the Long Island town, almost two dozen individuals are believed to have contracted the virus, with four confirmed cases and at least 14 suspected ones.”
“We are actually to the point that we are worried that this vaccine may indeed not be protecting against the strain of mumps that is circulating as well as it could.”
Dr. Dirk Haselow, Arkansas State Epidemiologist
Of course, to say that the vaccine may not be protecting folks “as well as it could” doesn’t mean it doesn’t work because the wild type mumps virus has evolved or mutated enough to surmount our current MMR vaccine.
Is Mutating Mumps More Than the MMR Can Manage?
Although anything is possible, we fortunately have plenty of research that says that the mumps virus hasn’t mutated and that the MMR still works.
In fact, although the MMR vaccine is made from the A strain or genotype of mumps, it provides good protection against all 12 known strains of wild mumps viruses, including genotype G that has been causing most of the recent outbreaks.
But how can it cover a different strain of virus that isn’t in the vaccine?
Because not all viruses and vaccines are like influenza.
“The genotyping of the mumps virus is based on the Small Hydrophobic (SH) protein, a nonstructural protein and genetically the most variable one. Based on the SH-protein 12 different mumps viruses were detected up to now. In recent epidemics in Western countries the genotype G was mainly detected, while the mumps viruses used in the live attenuated mumps vaccines belong to genotype A (Jeryl Lynn) and to a lesser extent to genotype B (Urabe). However, antibodies against the SH protein have not yet been observed in human serum. It is, therefore, unlikely that antibodies against the SH protein play an important role in antibody-mediated virus neutralization.”
Sabbe et al. on The resurgence of mumps and pertussis
It is well known that you need a very specific match of the flu vaccine to the wild flu virus that is going around to get good protection, but for many other viruses, the differences that determine the strain or genotype have nothing to do with how antibodies will recognize the virus.
“Since mumps virus is monotypic, vaccine from any strain should provide lifelong protection against subsequent infection.”
Palacios et al. on Molecular Identification of Mumps Virus Genotypes from Clinical Samples: Standardized Method of Analysis
“Studies have demonstrated that blood sera from vaccinated persons cross-neutralizes currently circulating mumps strains.”
CDC on Mumps for Healthcare Providers
And like measles, the mumps vaccine (MMR), protects against all strains of wild mumps viruses.
“Compared with attack rates of 31.8%–42.9% among unvaccinated individuals, attack rates among recipients of 1 dose and 2 doses of the Jeryl Lynn vaccine strain were 4%–13.6% and 2.2%–3.6%, respectively.”
Dayan et al. on Mumps Outbreaks in Vaccinated Populations: Are Available Mumps Vaccines Effective Enough to Prevent Outbreaks?
And like other vaccines, the mumps vaccine (MMR) works.
