Dr. Jim Meehan is another anti-vaccine physician who lacks credibility

This article about Dr. Jim Meehan was written by Dorit Rubinstein Reiss, Professor of Law at the University of California Hastings College of the Law (San Francisco, CA), who is a frequent contributor to this and many other blogs, providing in-depth, and intellectually stimulating, articles about vaccines, medical issues, social policy, and the law.

Professor Reiss writes extensively in law journals about the social and legal policies of vaccination. Additionally, Reiss is also a member of the Parent Advisory Board of Voices for Vaccines, a parent-led organization that supports and advocates for on-time vaccination and the reduction of vaccine-preventable disease. She is also a member of the Vaccines Working Group on Ethics and Policy.

An anti-vaccine doctor from Oklahoma, Dr. Jim Meehan, wrote an online post about why he would no longer vaccinate his children. It’s pretty clear that his post is not so much a discussion of his own children (most of whom are adults) as an attempt to deter other parents from protecting their children from preventable diseases. His post is basically a set of claims trying to convince parents that vaccinating is very dangerous.

His claims are nothing new – they are strictly out of the anti-vaccine playbook. But the post has received some attention in the anti-vaccine world and was shared several thousand times, likely because many people treat an MD as an authority on the subject. So I decided to take a few minutes to explain why his claims are not good reasons to reject expert opinion and not protect children from disease.

Since then, Dr. Jim Meehan has become one of the go-to anti-vaccine doctors who is trotted out to dismiss the safety and effectiveness of vaccines. Furthermore, he has become a COVID-19 denier, testifying against the use of face masks and claiming that the disease isn’t dangerous. Furthermore, Meehan was forced to settle a libel suit filed by Dr. Eve Switzer.

Dr. Meehan’s claims fall into several categories (which will be discussed individually below):

  1. The diseases we vaccinate against are not dangerous, and it’s okay, even good, to encounter them naturally.
  2. Vaccines have toxic ingredients.
  3. Vaccines are dangerous to children.
  4. The science behind vaccines is corrupt because the pharmaceutical industry controls it and then corrupts it.
  5. We should listen to him because he is a doctor and knows what he is talking about.

Note: Dr. Jim Meehan’s post doesn’t present these claims in that order. I have changed the order because I want to address the claims in a logical order, that is, first his claims about vaccine safety, then the conspiracy theory that underlies them, and finally, his appeal to authority

Jim Meehan

Category 1 – Actually, vaccine-preventable diseases are dangerous and potentially deadly

Dr. Meehan makes two claims in an attempt to contradict this important point:

…because I understand the risks of vaccination as well as the benefits of my children and grandchildren encountering and overcoming the wild type diseases naturally.

Dr. Meehan implies there are benefits of children encountering diseases naturally, and this sentence appears to apply to all preventable diseases we vaccinate against. But it’s not clear what benefits a child gets from contracting diphtheria, polio, tetanus, whooping cough, or Haemophilus influenzae type b (Hib). Diphtheria has a 10% mortality, as does tetanus.

Recovery from either would be, at best, hard and painful. Polio can paralyze or kill. As for the other diseases, they can, at least, cause substantial suffering. To remind Dr. Meehan, when vaccines prevent these diseases, they save tens of thousands of lives per year and prevent millions of hospitalizations (and see this review of an article that examines how many lives and sicknesses have been prevented by vaccines).  

Is it really a benefit to suffer from these diseases? I don’t know a lot of parents that would want that for their child.

…because I know that diseases like mumps, measles, and chickenpox aren’t dangerous and untreatable diseases that justify the risk of injecting toxic ingredients into the tissues of my children. 

It’s not clear why Dr. Jim Meehan thinks these viral illnesses are treatable, or how he would treat them. Experts suggest the treatment is essentially supportive of measles. I asked Dr. Paul Offit if that was true for varicella and mumps as well, and he said: “Varicella can be treated with acyclovir, typically given within 48 hours in immune-compromised hosts. But it’s not a wonder drug.”

It looks like the treatment options available are limited for all of these diseases.

Measles is the most severe of them. In the developing world, measles is a ferocious killer. In the developed world, it is less so, but it’s still not a mild disease. Over 10% of people with measles are hospitalized. One in a thousand has encephalitis, and (on average) about one in a thousand dies.

In young children, rates of subacute sclerosing panencephalitis (SSPE) – an always fatal complication – have been shown to be much higher than was previously thought, at around 1 in 1750-3300 in Germany and as high as 1:660 in children who get measles when they are under the age of 1 in California:

I’m not sure what Dr. Meehan’s standard is for this dangerous disease. This isn’t a risk I would want for my children.

Mumps and chickenpox’s complications are less common, but they do happen. And they are preventable by vaccination.

Category 2 – Factually, the tiny amounts of ingredients in vaccines are not an issue

Rarely, a person can have a severe allergic reaction to a vaccine, usually, though not always, to the gelatin in them. These reactions happen at a rate of about one per million.

But Dr. Meehan doesn’t even mention gelatin and is clearly not addressing this rare and remote risk. He is, instead, using a common anti-vaccine ploy referred to as “the toxins gambit.”

…because I have seen the evidence of neurotoxicity from ingredients like aluminum, Polysorbate 80, human DNA and cellular residues from the human cells lines upon which many of the live viruses are grown. 

The premise is that vaccine ingredients are dangerous. But in the form and in the tiny amounts in vaccines, these ingredients are not dangerous.

Vaccines use tiny amounts of aluminum salts to generate a stronger immune response (not elemental aluminum as Dr. Meehan’s comments may lead you to believe) – but those amounts are easily dealt with by the body, and are dwarfed by the amount of aluminum we get from food (more information here and here). Moreover, there is also no real indication that the tiny amounts of polysorbate 80 in vaccines are dangerous

As to the tiny amounts of DNA that might end up in vaccines, as was pointed out before, if it was that easy for fragments of DNA to affect the human body, gene therapy would be much easier. It’s not.

Finally, for those who would like to read more evidence-based information on why the toxin gambit is wrong, two of my favorite go-to sources are here and here (pdf).

Category 3 – Truth be told, vaccines are extremely safe

Dr. Meehan says:

…because I have met so many families whose children were stolen from them by the battery of vaccines administered at pediatric vaccine visits.

…because I believe the U.S. vaccination program has become a progressively dangerous assault on the health and lives of the children of America.

Note that Dr. Meehan’s first comment claims that children are “stolen” – echoing the claims made in old times of children being replaced by elves or witches. Those familiar with anti-vaccine terminology would realize he is referring to families who blame vaccines for a child’s autism.

But vaccines don’t cause autism, as studies in millions of children show. Autism causation lies elsewhere.

Further, it is an insult to autistic people to refer to them as “stolen”. The children are there. They are simply autistic.

The reality is that while nothing in life is completely safe, and vaccines can have harmful side effects, serious harms from modern vaccines are extremely rare. It is the opposite of an assault on children to protect them from diseases that can maim and kill them.

Category 4 – Honestly, an imaginary global conspiracy does not negate science.

The bulk of Dr. Meehan’s post consists of claims that vaccine science is bought by pharma and pharma is bad. Consider these comments:

…because I know that too much of the science supporting vaccines is fraudulent drivel bought and paid for by the vaccine manufacturers themselves.

…because I’ve seen vaccine manufacturers like Merck promote what they knew was bad medicine for profit, kill 60,000 patients with Vioxx, and I have no reason to believe that they wouldn’t do the same thing with vaccines, especially when you consider they can’t be sued when their vaccines maim or kill children. 

…because I believe the vaccine industry has thoroughly corrupted the science and safety of vaccines. 

…because I recognize the aggressive and unreasonable tactics of a multi-billion dollar pharmaceutical industry desperately working to maintain the illusion of vaccine safety, keep consumers consuming, grow their markets, and increase their profits.

…because I am awake and aware, I will not vaccinate, nor will I remain silent as the pharmaceutical and medical industries pretend that vaccines are safe and effective.

Let me start by saying that I would not want to have to trust for-profit corporations to be upfront about vaccine safety, especially not when, as Dr. Jim Meehan correctly points out, several of our pharmaceutical companies have engaged in problematic behavior in the past (though note:  he had to step outside the vaccine realm for an example because he is unable to point to a recent vaccine scandal with one of our companies – to my knowledge, there isn’t one).

But I don’t need to trust. There are literally tens of thousands of safety studies about vaccines. They come from all around the world. They are funded by multiple sources, as looking at their funding statements can tell us – by pharmaceutical companies, but also by governments – different governments, including those with national health insurance systems and a strong incentive to cut costs, non-profits, universities.

They are done, usually, by large, multi-member teams of researchers. And on each point related to vaccine safety, we usually have several studies that reaffirm each other. On top of that, governments all over the world monitor vaccine safety after they are administered.

To believe all of that science is corrupt, you have to assume a degree of collusion and control that is simply fantastic. You have to assume that pharmaceutical companies can control or mislead thousands of researchers, and hundreds of thousands of doctors, and governments all over the world.

Accepting such a global, far-reaching conspiracy requires ignoring basic realities about the ability to manage such a large-scale deception. It’s just impossible.

This belief also doesn’t fit the reality of what happens when there is an actual problem with vaccine effectiveness or safety. When some H1N1 influenza vaccines in Europe caused a few cases of narcolepsy, it was front-page news.

When some children were harmed in Australia because they were given a vaccine not appropriate for their age, it was front-page news. When evidence on the lack of effectiveness of pertussis vaccines came out, it was front-page news. When the flu vaccine was ineffective a few years ago, it was front-page news.

In a well-known example, when a newly approved rotavirus vaccine – Rotashield – was found to cause a serious side effect in about 1 in 10,000 children (and also here),  the vaccine was pulled off the market – and the issue was front-page news. The next generation of rotavirus vaccines was then required to be tested in tens of thousands of children.

These cases demonstrate that vaccine problems are anything but hidden.

Belief in a grand conspiracy of silence and globally controlled science on vaccines is just unrealistic, and against the evidence.

Category 5 – Finally, Dr. Jim Meehan is not a vaccine expert

Dr. Meehan opens his post with a call to heed him because his qualifications make him an authority on the topic. He says:

…because I am a well trained medical doctor and former medical journal editor that has studied the vaccine research and analyzed both sides of the evidence. 

…because I know how to read the medical literature, recognize bias and discern characteristics of good and fraudulent research.

I left this issue till last because it’s more important to focus on the claims than on the person. But since Dr. Jim Meehan is drawing on his authority as a doctor, and using his position to call on people to trust him, it is worth addressing.

Dr. Meehan was trained as an ophthalmologist but is now working on other areas, with an apparent focus on creating electronic tools to handle health problems. He has no expertise or experience in any of the biomedical fields that are related to vaccine research – public health, pediatrics, infectious diseases, virology, microbiology, immunology, or epidemiology.

He has no publications indexed in PubMed (all of the articles published by a “James Meehan” are from a UK-based cancer researcher, not Dr. Jim Meehan, the subject of this article) and no publications are listed on his site. He has published nothing that shows he seriously engaged with the extensive literature on vaccines. That may not disqualify him from criticizing a specific scientific article, but it also does not qualify him to counter the scientific consensus of those who are familiar with the literature and do understand infectious diseases and vaccines.

In fact, his comments show that he rejects most of the science developed by those experts in fields related to vaccines.


Dr. Jim Meehan does have medical training, though it is not related to vaccines. He has no demonstrated expertise relevant to vaccines. His comments repeat well-familiar – and incorrect – anti-vaccine tropes. It is more troubling that a medical doctor is willing to make such claims than it is when a layperson does that. It seems like a misuse of the authority his medical training confers on him.
