Is the Meningococcal Vaccine More Dangerous Than Meningococcal Disease?

No one who has ever seen a child with meningococcal disease would ever think that it was even remotely possible that getting a meningococcal vaccine was more dangerous than getting the disease.

“The case-fatality ratio of meningococcal disease is 10% to 15%, even with appropriate antibiotic therapy. The case-fatality ratio of meningococcemia is up to 40%. As many as 20% of survivors have permanent sequelae, such as hearing loss, neurologic damage, or loss of a limb.”

Epidemiology of Vaccine Preventable Diseases (PinkBook)

Of course, that doesn’t stop anti-vaccine folks from spreading misinformation about these vaccines to try and scare parents away from vaccinating and protecting their kids.

Is the Meningococcal Vaccine More Dangerous Than Meningococcal Disease?

We actually vaccinate against meningitis with many different vaccines, including Hib, Prevnar, MMR, and the meningococcal vaccines.

And there are different types of meningococcal vaccines, including those that protect against Neisseria meningitidis serogroups A, C, W, Y and Men B.

Meningococcal vaccines are safe and effective against meningococcemia and meningococcal meningitis, both terrible diseases.
Meningococcal vaccines are safe and effective against meningococcemia and meningococcal meningitis, both terrible diseases.

So routine vaccinations likely prevent up to 500 meningitis deaths each year, just in the United States, including many deaths from Hib meningitis, pneumococcal meningitis, and meningococcal disease.

“During 2005-2011, an estimated 800-1,200 cases of meningococcal disease occurred annually in the United States, representing an incidence of 0.3 cases per 100,000 population.”

Epidemiology of Vaccine Preventable Diseases (PinkBook)

What about the idea that 1 in 100 people will have a serious reaction to the vaccine?

“The most frequently reported adverse events for MenACWY-D include fever (16.8%), headache (16.0%) injection site erythema (14.6%), and dizziness (13.4%). Syncope was reported in 10.0% of reports involving MenACWY-D. Of all reported MenACWY-D events, 6.6% were coded as serious (i.e., resulted in death, life-threatening illness, hospitalization, prolongation of hospitalization, or permanent disability). Serious events included headache, fever, vomiting, and nausea. A total of 24 deaths (0.3%) were reported.”

Epidemiology of Vaccine Preventable Diseases (PinkBook)

The serious events listed above were from the clinical trials for the vaccine and didn’t differ between the vaccine and placebo.

Although meningococcal vaccines can have frequent mild side effects, they very rarely have serious side effects.

Not everything that happens during a clinical trial is related to the vaccine, even though it still gets reported. Another Menactra trial reported no deaths and the serious adverse events that were reported weren’t related to getting vaccinated.

Here is another meningococcal study in which a few of the participants died – one in a car accident and the other a drug overdose.

These deaths were not related to getting vaccinated, but were listed because they occurred during the study.
These deaths were not related to getting vaccinated, but were listed because they occurred during the study.

Unfortunately, vaccines can’t protect you from everything…

It would be especially nice if they could protect us from bad anti-vaccine memes.

Retired Hospital Worker’s Flu Shot Speech at the ACIP Meeting

Did you see the video of the retired hospital worker, an emergency room technician, at the ACIP meeting earlier this year?

A retired emergency room technician gave a speech at an ACIP meeting because she is upset that hospital workers have to get yearly flu shots.
A retired emergency room technician gave a speech at an ACIP meeting because she is upset that hospital workers have to  either get yearly flu shots or wear a face mask.

Although brief, and emotional, she hit a lot of anti-vaccine talking points and managed to somehow talk about adult autistics walking around the mall with diapers and helmets at least four times.

Retired Hospital Worker’s Flu Shot Speech at the ACIP Meeting

Praised by anti-vaccine folks for being “explosive” and a “bombshell,” all the speech really does is reveal how easily influenced some folks are by the modern anti-vaccine movement.

“I don’t come here with any degree.”

The only true and one of the most important things she says comes at the beginning. Although it certainly isn’t a requirement to have a degree to speak your mind, in a room full of scientists and doctors who study health policy and vaccines as their life’s work, she was there to tell them that they were wrong.

“No one believes in the flu shots. My colleagues. I didn’t. Because the efficacy – and I won’t give you data, you created the data. 10% one year. 18% another year. 40% at best. And the FluMist you gave to our children from 2 to 8 years for almost 4 years – it never worked. 3%. Oh well.”

Most people actually understand that flu vaccines are important and many get a flu shot each year. Even more get their kids vaccinated and protected each year.

In most years, the flu vaccine is at about 40 to 50% effective at preventing the flu, but has other benefits, including preventing a severe case of the flu, getting hospitalized, and keeping you from dying with the flu!

Did a drop in flu vaccine coverage help contribute to a rise in flu deaths?
Did a drop in flu vaccine coverage help contribute to a rise in flu deaths?

The idea that “no one believes in flu shots” is silly. It is certainly possible that no one this speaker knows believes in flu shots, as many anti-vaccine folks exist in an echo chamber and only hear and read negative things about vaccines.

Her statements about flu vaccine efficacy are also way off, especially about FluMist, as there was only evidence that it didn’t work well against H1N1 flu strains for a few years.

“And then came your mandates. And then came your recommendations. So you know what, for four years before I retired I put a mask on. 12 hour shifts. It wasn’t easy to breath. But that’s how much I didn’t believe in your efficacy.”

Neither the CDC or ACIP mandate that hospital workers get a yearly flu shot.

It is recommended and it is the ethical thing to do, so that we protect our most vulnerable patients, including those who can’t be vaccinated, but the CDC doesn’t issue mandates.

“But the truth. The public’s truth. My observation – which is the first step in scientific theory – they didn’t believe in your shot.”

Making an observation is actually the first step in the scientific method. But you don’t stop there. Why don’t they believe in flu vaccines? Are they scared about all of the anti-vaccine propaganda that they see and read on the Internet or even from anti-vaccine friends or coworkers?

“This year I retired. I’m grateful for that, because my soul was sick about what I saw go on. That flu shot was crazy. First it was 10%. How can you do data? Which 10 got the shot out of a 100?”

How do they know which 10 got the shot?

Believe it or not, when they tell us about flu vaccine effectiveness, they are not basing that number on each and every person who got a flu vaccine. They do a study, enroll patients, see if they get flu, see if they had a flu vaccine, compare them to other patients, etc. It’s actually very easy to tell which ones got the shot…

“I’m looking around, some of you are my age. And if I’m mistaken, I apologize. But I’m in a generation where I got 7 shots. 26 years later, my daughter got 10. Her son got, maybe 60. My new grandson is expected to get maybe 72, and I just watched you add more.”

Yes, a lot has changed from her generation.

Four generations of vaccines or vaccine misinformation?
Four generations of vaccines or vaccine misinformation?

Our now vaccinated kids don’t die from Hib meningitis, Hib epiglotittis, pneumococcal disease, rotavirus, chicken pox, hepatitis A, hepatitis B, measles, etc., and they don’t get congenital rubella syndrome!

And for the record, her new grandson won’t need 72 shots or more.

They didn’t add any more at that ACIP meeting she gave her speech at either.

“Robert Kennedy, Jr – do you know what he says? His family started Special Olympics – there were no autistic kids. He says, where are the 40 year olds wearing diapers with helmets on at the mall if you misdiagnosed them. If you missed them, because you say it’s not vaccines,  where were the special ed classes for people in my generation – there weren’t any. Because they didn’t exist.”

Special education classes didn’t exist back then, because we didn’t start getting things like that until passage of the Education for All Handicapped Children Act in 1975. Before that, many states actually had laws excluding special needs children from school!

So there weren’t any special ed classes because they weren’t available, not because they weren’t needed.

And as the first school for autistic children, the Sybil Elgar School, was established in 1965, it should be obvious that her comments about autistic adults are not only wrong, they are offensive.

“I don’t care what you say that the autism and vaccines don’t exist – it does. I watched a perfectly healthy beautiful 2-year-old get those shots and become a severe autistic child. And guess what, he will be 40 and walking around the mall with a diaper on and helmet.”

This is everything that is wrong with the modern anti-vaccine movement.

Continuing to push the idea that vaccines are associated with autism and being locked into a deficit model of thinking about autism, so that when you look at your child, all you see is an adult with a “diaper on and helmet,” instead of beautiful autistic 2-year-old.

Ironically, she ended her speech with this quote by William Wilberforce.

“Having heard all of this you may choose to look the other way but you can never again say you did not know.”

William Wilberforce

Nothing she said was true and some of it was actually offensive.

You can’t say you don’t know now.

This Is the Modern Anti-Vaccine Movement

We often like to think that we know how anti-vaccine folks think.

They are just scared and trying to do the right thing for their kids, right? Just like all of the rest of us?

Maybe some of them…

This Is the Modern Anti-Vaccine Movement

Of course, you can’t group all anti-vaccine folks together, as many vaccine-hesitant or on-the-fence parents are truly just scared about the things they see and read about vaccines.

But they should know what they are getting into when they follow their favorite anti-vaccine hero, celebrity or Facebook group.

The modern anti-vaccine movement goes far deeper than worries about possible vaccine side effects.

Don’t believe me?

Learn the risks of following bad advice.

After all, it’s one thing to consider skipping or delaying your child’s vaccines when you think you can get away with hiding in the herd or to buy some essential oils and supplements, but are you really going to say no to chemotherapy if your child has cancer? Brandy Vaughan seems to think you should.

If there is a RISK, there must be a CHOICE.

Do you think it is okay to put infants who are too young to be vaccinated at risk for measles and other vaccine-preventable diseases because you don’t like the choices you have been given between getting your kids vaccinated and protected or keeping them out of school?

What about the parents of the kid who is being treated for cancer who gets exposed to chicken pox because someone else made the choice to not vaccinate their kid? Do you think that’s fair?

The modern anti-vaccine movement is only about choice when it is about their choices and doesn’t seem to care about the risks their unvaccinated kids pose to others.

Believe it or not, the modern anti-vaccine movement also equates getting vaccinated with rape…

Don’t believe me?

Meryl Dorey has also claimed that vaccination is rape.

Who Dies from Chicken Pox?

Chicken pox is supposed to be a mild disease, right?

A rite of passage for kids?

“My life changed forever on June 30, 1988, when I had to stand by helplessly as an infectious disease claimed the life of my oldest child, Christopher Aaron Chinnes, at the age of 12.”

Rebecca Cole on Chickenpox Claimed the Life of My Son Christopher

Sure, a deadly rite of passage that we had to hope that our kids got through unscathed…

Who Dies from Chicken Pox?

Believe it or not, some folks continue to think that chicken pox was never deadly, even as kids continue to die from this now vaccine-preventable disease.

Remember, the chicken pox vaccine was added to the vaccine schedule way back in 1996, after being licensed in 1995.

Chicken pox can kill quickly.
Chicken pox can kill quickly.

Tragically, there are plenty of stories and case reports that prove them wrong:

  • a previously healthy, unvaccinated 23-month-old boy developed chicken pox and died three weeks later after developing sepsis, possible viral meningoencephalitis, bacterial endocarditis, and heart failure. (1996)
  • a previously healthy, unvaccinated 21-month old developed chicken pox and died four days later because of hemorrhagic complications (1997)
  • an unvaccinated 5-year-old boy with asthma was treated with one dose of prednisone at home for an asthma attack while recovering from chicken pox and died the next day (1997)
  • a healthy, unvaccinated 6-year-old boy developed chicken pox, was hospitalized three days later, and died the next day (1998)
  • an 8-year-old being treated for leukemia developed chicken pox and died two weeks later (1998)
  • an unvaccinated 9-year-old girl was exposed to an unvaccinated children with chicken pox in after-school child care and school, developed chicken pox and died three days later with secondary cellulitis and sepsis. (2002)
  • a previously healthy, unvaccinated 11-year-old girl developed septic shock and died soon after being admitted to a Pediatric Intensive Care Unit. (2002)
  • an unvaccinated 12-year-old boy was exposed to an unvaccinated classmate with chickenpox, developed chicken pox two weeks later, was admitted to the hospital after three days because of trouble breathing, and died on his second hospital day after suffering a cardiopulmonary arrest. (2003)
  • an unvaccinated 10-year-old girl developed chicken pox, with worsening 10 days later, including ataxia and mental status changes. After being hospitalized for three days, she began to have seizures  and was declared brain dead the next day. (2004)
  • an unvaccinated 14-month-old girl developed chicken pox and worsened over the next three to five days. She eventually developed septic shock, was treated in an ER, and died within one hour of being transferred to a children’s hospital for further care. (2004)
  • a previously healthy, unvaccinated 15-year-old developed chicken pox, was admitted to the hospital three days later in septic shock, and died three weeks later. (2009)
  • a partially vaccinated 4-year-old girl who was being treated for acute lymphoblastic leukemia (ALL) was exposed to a cousin with chicken pox and later developed multi-organ failure and died (2012)

Chicken pox has always been a deadly disease.

“In the prevaccine era, approximately 11,000 persons with varicella required hospitalization each year. Hospitalization rates were approximately 2 to 3 per 1,000 cases among healthy children and 8 per 1,000 cases among adults. Death occurred in approximately 1 in 60,000 cases. From 1990 through 1996, an average of 103 deaths from varicella were reported each year. Most deaths occur in immunocompetent children and adults”

Epidemiology and Prevention of Vaccine-Preventable Diseases

Although chicken pox is definitely riskier if you are older and have pre-existing medical problems, as you can see from these kids who died, many were otherwise healthy and many were very young.

And almost all were unvaccinated, even though a safe and effective chicken pox vaccine could have prevented these deaths and probably the exposures that led to the deaths of the high risk kids being treated for cancer.

The National Vaccine Injury Compensation Program Payouts Prove that Vaccines are Dangerous

Have you heard this argument?

Misinformation about the NVICP, like from this Focus for Health article, likely helps confuse and scare many parents.
Misinformation about the NVICP, like from this Focus for Health article, likely helps confuse and scare many parents.

Apparently, some folks think that because we have a National Vaccine Injury Compensation Program that compensates those who have serious problems after a vaccine, even deaths, then it must mean that vaccines are dangerous.

Do the National Vaccine Injury Compensation Program Payouts Prove that Vaccines are Dangerous?

To most other people, that argument doesn’t hold water.

Why?

Because we know that:

  • the National Vaccine Injury Compensation Program is a no-fault alternative to the traditional legal system for resolving vaccine injury petitions
  • of over 3.1 billion doses of vaccines that were distributed in the United States between 2006 and 2016, there were 3,749 compensated claims through the NVICP
  • almost 80% of all compensated awards by the NVICP come as a “result of a negotiated settlement between the parties in which HHS has not concluded, based upon review of the evidence, that the alleged vaccine(s) caused the alleged injury.”
  • the NVICP settlements are funded by an excise tax on vaccines
  • the NVICP cases are published by the U.S. Court of Federal Claims, so all information is disclosed to the public and no safety concerns are hidden

So what does the National Vaccine Injury Compensation Program (VICP) really prove?

It proves that true vaccine injuries are very rare – about 1 in a million rare.

It proves that while vaccines are not 100% safe, they are very safe.

Certainly safer than the complications of a vaccine-preventable disease.

And it proves that anti-vaccine arguments are very easy to refute

Does Japan have the Lowest Infant Mortality Rate Following a Ban on Mandatory Vaccinations?

Vaccines don’t affect infant mortality rates as much as you would expect, because there are many other things that kill infants besides vaccine-preventable diseases. Things like birth defects, prematurity, injuries and complications during pregnancy.

Unfortunately, that gives anti-vaccine folks lots of opportunities to misuse statistics about infant mortality rates.

Does Japan have the Lowest Infant Mortality Rate Following a Ban on Mandatory Vaccinations?

The latest propaganda about vaccines and infant mortality rates relates to Japan.

“It may come as no surprise to many that the Japanese Government banned a number of vaccines that are currently mandatory in the United States and has strict regulations in place for other Big Pharma drugs and vaccines in general.”

Jay Greenberg on Anti-Vaccine Japan Has World’s Lowest Child Death Rate, Highest Life Expectancy

Most folks will understand why this is simply propaganda.

Japan never banned any vaccines.

The 2016 routine and voluntary immunization schedule in Japan.
The 2016 routine (Hib, Prevnar, hepB, DTaP, IPV, BCG, MR, Varicella, Japanese Encephalitis, DT, and HPV) and voluntary (mumps, rotavirus, hepA, meningococcal) immunization schedule in Japan.

Japan is not anti-vaccine. Although their immunization schedule is certainly a lot more complicated than ours, they give many of the same vaccines as every other developed country.

“Following a record number of children developing adverse reactions, including meningitis, loss of limbs, and even sudden death, the Japanese government banned the measles, mumps, and rubella (MMR) vaccine from its vaccination program, despite facing serious opposition from Big Pharma.”

Was the MMR vaccine banned in Japan?

The MMR vaccine was introduced in Japan in 1989, and four years later, the government withdrew its recommendation for the vaccine.

Why? Reports of aseptic meningitis. This was likely due to the Urabe strain of the mumps component in their MMR vaccine, which was not used in the United States.

“The data up to now have revealed low rates of aseptic meningitis and no cases of virologically proven meningitis following the use of Jeryl–Lynn and RIT 4385 strains.”

WHO on Safety of mumps vaccine strains

They didn’t ban the vaccine or vaccination though.

They returned to giving children separate measles, rubella, and mumps (optional) vaccines. Tragically, because many kids didn’t get vaccinated against mumps, the rate of aseptic meningitis from people who actually got mumps was 25 times higher than the rate from the MMR vaccine!

When comparing risks vs benefits, it clearly favored getting vaccinated.

“Due directly to these gaps in ‘herd’ immunization resulting from politicized transitions in vaccination policy by the government, there were outbreaks of rubella with 17,050 cases reported between the years of 2012 and 2014, and 45 cases of congenital rubella syndrome reported to the National Epidemiological Surveillance of Infectious Diseases from week 1, 2012 to week 40, 2014.”

Yusuke Tanaka on History repeats itself in Japan: Failure to learn from rubella epidemic leads to failure to provide the HPV vaccine

The switch over also lead to outbreaks of rubella and increased cases of congenital rubella syndrome.

That’s no surprise to those who remember what happened in 1975, when routine pertussis vaccinations were halted in Japan following the deaths of two children. That eventually lead to epidemic cases of whooping cough in the country and at least 41 deaths in children (in 1979) before the vaccine was restarted.

Unfortunately, once they moved to DTaP vaccines, they started to see an increase in allergic reactions after kids got their MMR vaccine. Why? Their version of the DTaP vaccine contained poorly hydrolyzed bovine gelatin, which likely sensitized infants, who then developed an allergic reaction after getting an MMR vaccine with gelatin. While gelatin was removed from their DTaP vaccines, these extra side effects likely scared some folks in Japan.

Japan’s Vaccine Problem

Japan has more vaccine-preventable diseases than many other industrial countries.

Is it because Japan is anti-vaccine?

Of course not.

By impulsively halting and withdrawing vaccines, the Japanese government has done a good job of scaring folks though. They have also been very slow to introduce new vaccines, although they are catching up, as hepatitis, B, rotavirus, Hib, pneumococcal, meningococcal, HPV, and the chicken pox vaccine are all now available in Japan.

Have there been any benefits?

Nope.

They might have lower infant mortality rates, but that has nothing to do with vaccines.

There is no correlation between the number of vaccines that a country gives and their infant mortality rate.

If infant mortality rates are linked to vaccines, how do you explain Finland?
If infant mortality rates are linked to vaccines, how do you explain Finland?

Just look at the immunization schedules in Finland, Portugal, and other countries.

What about autism?

Rates of autism have increased in Japan, just as they have in other countries. So much for the idea that the MMR vaccine is associated with autism, right?

It should be obvious now that if anti-vaccine folks did any research at all, they wouldn’t use Japan as an example when they talk about vaccines.

With higher rates of vaccine-preventable disease and deaths from vaccine-preventable diseases, especially right after they impulsively halt a vaccine, Japan’s vaccine history simply demonstrates that vaccines work and that they are still very necessary.

One thing is true though. Japan’s infant mortality rate has been dropping, but then so has the infant mortality rate in almost all other countries, including the United States, which is at record low levels.

It certainly isn’t true that Japan’s infant mortality rate started to drop following a ban on mandatory vaccinations. How do we know that? Like many other countries, Japan has never had mandatory vaccinations. And not surprisingly, their infant mortality rate has continued to drop as they have added more vaccines and improved their immunization rates.

Why Are the DPT and OPV Vaccines Still Used in Some Countries?

As most folks know, neither the DPT nor OPV vaccines are used in the United States.

Pope Francis helped launch a polio vaccine campaign when he visited Mexico in 2016.
Pope Francis helped launch a polio vaccine campaign when he visited Mexico in 2016.

That they are still used in other countries likely raises some questions for those folks that get them.

Why Are the DPT and OPV Vaccines Still Used in Some Countries?

As I am sure you have guessed, there is no conspiracy about the continued use of these vaccines in other parts of the world. We aren’t getting rid of old stocks of vaccines or using cheaper vaccines in poorer parts of the world.

So what’s the reason?

To understand why they are still used in other countries, it helps to understand why they aren’t used here.

Remember that the DPT vaccine, which protects folks against diphtheria, pertussis, and tetanus, came under attack in the 1970s and 80s as some folks blamed the vaccine for causing vaccine injuries, including seizures and encephalopathy. It didn’t, but we still got a new vaccine, DTaP, which doesn’t seem to work as well.

“Although concerns about possible adverse events following their administration have led to the adoption of acellular pertussis vaccines in some countries, whole-cell pertussis vaccines are still widely produced and used globally in both developed and developing countries. Whole-cell pertussis vaccines that comply with WHO requirements, administered according to an optimal schedule have a long and successful record in the control of whooping cough. Furthermore, the excellent efficacy of some currently available whole-cell pertussis vaccine has also been shown, not only in recent clinical trials, but also on the basis of the resurgence of disease where vaccination has been interrupted or when coverage has markedly decreased. Therefore, WHO continues to recommend whole-cell pertussis vaccines for use in national immunization programmes.”

WHO on Recommendations for whole-cell pertussis vaccine

The WHO now recommends that if countries do switch to DTaP,  the acellular pertussis vaccine, they should be prepared to add additional periodic booster doses and immunizations during pregnancy, which may still “may not be sufficient to prevent resurgence of pertussis.”

The OPV vaccine, on the other hand, was replaced because it can rarely cause vaccine-associated paralytic polio (VAPP) and circulating vaccine-derived polio virus (cVDPV). Of course, it does it at much lower rates than wild polio virus, so until polio is well controlled, the benefit of using OPV outweighs the risk. In addition to being less expensive and easier to use, OPV has the benefit over IPV of providing better herd immunity.

At some point, as we did in the United States in 2000, countries make a switch to the IPV vaccine.

In 2016, remaining countries that use OPV switched from trivalent OPV to bivalent OPV, because wild polio virus type 2 was eradicated in 1999. Once the remaining two types are eradicated, we can stop using the OPV vaccine altogether.

Until then, countries either use:

  • OPV plus one dose of IPV
  • sequential IPV-OPV schedules – high vaccine coverage and low risk of wild polio importation
  • IPV only schedules – sustained high vaccine coverage and very low risk of wild polio importation

So there is no conspiracy. These vaccines are safe and they work.

Without them, there would be over:

  • 1.3 million pertussis related deaths each year
  • 600,000 cases of paralytic polio each year

With most of these cases affecting young children.
