A Crazymother Visits Her Pediatrician to Talk About Vaccines

There is a new Crazymothers video floating around and it is everything that’s wrong with the modern anti-vaccine movement.

What is so shocking about a pediatrician educating a mother about the importance of vaccinating and protecting her child? — What is so shocking about a pediatrician talking to a mother about the importance of vaccinating and protecting her child?

On the fence parents are being told ‘this this and this’ by their pediatricians and then going to someone who has found Internet fame making Crazymothers videos to find out if they are true.

As you might expect, her videos include:

anti-vaccine talking points
anti-vaccine myths
ideas that autism can be cured
misinformation about VAERS
Big Pharma conspiracy theories
the bonus check conspiracy theory

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

Crazymothers?

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?”

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:

they are scared
they are getting influenced to make their decision in anti-vaccine Facebook groups, which are essentially echo-chambers of anti-vaccine misinformation and propaganda
they are doing their own research, but are not using reputable sources
they are influenced by vaccine injury videos

Mostly they are scared. Hopefully this mom does some more research, gets more answers to her questions, and does change her mind soon.

Crazymothers Propaganda

The video, most which I have transcribed, also illustrates why it is important to be prepared when you talk to your pediatrician about vaccines. After all, you can’t get your questions about vaccines answered if you don’t ask any questions.

“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?

It is actually very simple.

They are at increased risk for vaccine-preventable diseases.

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.”

yeah

“And also keep in mind that in terms of autism, the study that was done in England years ago that supposedly linked autism to the measles, mumps, and rubella vaccine was tainted. It was funded by anti-vaccine lawyers, was retracted by every single person that offered that study and because of that study, children didn’t get the MMR and many died.”

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.

Nobody died?

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.

MMR vaccination rates had dropped below 80% by 2003, when the first measles outbreaks in the UK began. They didn't fully recover until 2012. — MMR vaccination rates had dropped below 80% by 2003, when the first measles outbreaks in the UK began. They didn’t fully recover until 2012.

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.”

Andrew Wakefield

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?

Herd immunity myth?

The idea that herd immunity is a myth because adults aren’t vaccinated is silly.

Adults were either born in the pre-vaccine era and likely have natural immunity or were born in the vaccine era and are vaccinated and immune, as many vaccines provide life-long immunity. That’s why adults get few boosters or catch-up vaccines.

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.

In 1951, during the first season of I Love Lucy, you can see that they had indoor plumbing. Surprised? — In 1951, during the first season of *I Love Lucy*, you can see that they had indoor plumbing. Surprised?

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?

Polio.

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.

How To Counter Vaccine Hesitancy

There is nothing wrong with having questions about vaccines. And there is certainly nothing wrong with doing a little, or even a lot of research about vaccines.

“We are not against vaccines. Just because we have hesitancies and valid concerns about injecting our baby with specific chemicals and toxins does not mean we are anti anything…

As a soon-to-be-parent [and especially as a first-time-mom] I do feel it my responsibility to have questions, and to listen to my motherly instinct to question things, and do my research.”

Kat Von D

The problem comes when the answers folks get come from misinformation, and it leads them to skip or delay their child’s vaccines, leaving them unprotected.

What is Vaccine Hesitancy?

To counter vaccine hesitancy, you likely first need to understand what it means.

“Vaccine hesitancy refers to delay in acceptance or refusal of vaccines despite availability of vaccination services. Vaccine hesitancy is complex and context specific varying across time, place and vaccines. It includes factors such as complacency, convenience and confidence.”

SAGE Vaccine Hesitancy Working Group

So it means someone who is anti-vaccine, right?

Not exactly.

“Although many may characterize all individuals who eschew vaccines as “anti-vaccine” or “vaccine deniers,” in reality there is a broad spectrum of individuals who choose not to have themselves or their children vaccinated.”

Tara C Smith on Vaccine Rejection and Hesitancy: A Review and Call to Action

Many of the folks who are vaccine hesitant aren’t truly anti-vaccine. They are likely being misled by anti-vaccine myths and propaganda, but at least they aren’t the ones spreading it across Facebook or on their own blogs and anti-vaccine websites.

How To Counter Vaccine Hesitancy

How do you counter vaccine hesitancy?

“It’s unfair for anyone to expect me [or any parent] to take the word of the pharmaceutical companies who have much to gain from and industry worth billions without question – and then have to dismiss any concerns of my own.”

Kat Von D

You learn to answer all of the questions and concerns that these parents might have about vaccines and vaccine-preventable diseases, including the risks and benefits of vaccines and the risks of being unvaccinated.

“Well, if you’re going to inform yourself about vaccines, I think anybody who’s truly informed will realize that getting a vaccine is much better than not getting one. If you’re choosing not to vaccinate your child, it’s because you’re getting, frankly, bad information about vaccines.”

Paul Offit, MD

You also make sure that parents, teachers, nurses, doctors, pharmacists, reporters, and everyone else gets good information about vaccines.

And you call out the misinformation and out-right lies of the anti-vaccine movement, especially when they say that vaccines never work, are always dangerous and full of toxins, or aren’t necessary.

You don’t let parents get manipulated by the anti-vaccine industry, which has gotten very good at selling fear – literally.

Like the card trick in My Cousin Vinny, anti-vaccine talking points are easy to explain because they are all an illusion. — Like the card trick in *My Cousin Vinny*, anti-vaccine talking points are easy to explain away, because they are all an illusion.

Remember, there is not one anti-vaccine argument or talking point that ever holds water.

Why not?

Because unless you go cherry picking, the evidence overwhelmingly shows that vaccines work, vaccines are safe, and vaccines are necessary.

What to Know About Countering Vaccine Hesitancy

If you are on the fence or scared to vaccinate your kids, let us help you learn why vaccines are safe and necessary and arguments against vaccines never hold water.

Are Anti-Vaccine Folks Smarter Than the Rest of Us?

For the overwhelming majority of us, it seems like a simple decision – get your kids vaccinated and protected and avoid all of the risks of vaccine-preventable diseases.

After all, we understand that vaccines are safe and necessary.

But folks who choose to skip or delay vaccines want to do what is best for their kids too, even as they come to the exact opposite decision, so who is making the smarter choice?

Are Anti-Vaccine Folks Smarter Than the Rest of Us?

Not surprisingly, anti-vaccine folks think they are smarter.

Why?

“In the end we are left with a powerful sense of knowledge – false knowledge. Confirmation bias leads to a high level of confidence, we feel we are right in our gut. And when confronted with someone saying we are wrong, or promoting an alternate view, some people become hostile.

The Dunning-Kruger effect is not just a curiosity of psychology, it touches on a critical aspect of the default mode of human thought, and a major flaw in our thinking. It also applies to everyone – we are all at various places on that curve with respect to different areas of knowledge. You may be an expert in some things, and competent in others, but will also be toward the bottom of the curve in some areas of knowledge.”

Steven Novella on Lessons from Dunning-Kruger

While it is easy to blame it on the Dunning-Kruger effect, a study that appeared in the July 2004 issue of Pediatrics, Children who have received no vaccines: who are they and where do they live?, is often used by anti-vaccine folks to reinforce the idea that they are smarter.

“Undervaccinated children tended to be black, to have a younger mother who was not married and did not have a college degree, to live in a household near the poverty level, and to live in a central city. Unvaccinated children tended to be white, to have a mother who was married and had a college degree, to live in a household with an annual income exceeding 75,000 dollars, and to have parents who expressed concerns regarding the safety of vaccines and indicated that medical doctors have little influence over vaccination decisions for their children”

Children who have received no vaccines: who are they and where do they live?

But the part of the study that is often quoted is comparing unvaccinated vs undervaccinated.

In the same study, the education level of unvaccinated vs vaccinated is virtually the same.

And the differences for the unvaccinated vs undervaccinated kids was about their living near the poverty level. If these families grew up with less money, they likely had less opportunities to go to school, and unfortunately, had less opportunities to keep their kids up-to-date on their vaccines.

One study, Maternal characteristics and hospital policies as risk factors for nonreceipt of hepatitis B vaccine in the newborn nursery, did seem to associate a higher education level with refusing the newborn hepatitis B vaccine, but an even bigger factor was being born in a facility that actually had a policy that offered the vaccine.

“Likewise, vaccine refusal now appears to be less a function of socioeconomic status than it once was. Previously, maternal education was strongly associated with vaccine refusal, but now mothers without a high school diploma are even more likely than college graduates to have unvaccinated children . Also, unvaccinated children are no longer found primarily in the highest income households (perhaps a function of income data being top-coded at $50,000), but now are equally likely to live in households with more moderate (or even below poverty) incomes.”

Laura Blakeslee on Trends and Characteristics of Unvaccinated Children in the United States : The National Immunization Survey, 2002 − 2010

Other studies have either showed a higher level of college graduates for those who vaccinated their kids or no difference.

What about all of the experts in the anti-vaccine movement? Remember that the heroes and so called experts of the the anti-vaccine movement mostly includes celebrities, some doctors and scientists who are practicing way out of their field of expertise when they talk about vaccines, and others whose work is not supported by the great majority of experts in their field.

That’s not necessarily the end of the story though.

Yet another study (a small survey), Parental Delay or Refusal of Vaccine Doses, Childhood Vaccination Coverage at 24 Months of Age, and the Health Belief Model, found that as compared to parents who vaccinated their kids, those who delayed or refused vaccines:

were less likely to think that vaccines were necessary
were less likely to think that their kids would get a disease if they weren’t vaccinated
were less likely to believe that vaccines are safe
were more likely to believe that vaccines caused serious side effects
were more likely to believe that children get too many vaccines

And surprisingly, considering that the above things are basically anti-vaccine talking points that are easily disproven, they were actually more likely to have gone to college and to be a college graduate. It is not a surprise that they were less likely to have a good relationship with their doctor and were less likely to believe that their doctor had their child’s best interest at heart.

Parents unknowingly gave their infants teething powder made with mercury, causing pink disease or mercury poisoning. Ironically, a decrease in illiteracy levels might have been the cause.

So maybe some anti-vaccine parents are indeed well-educated about some things, but that just gets us back to the Dunning-Kruger effect, as they certainly aren’t making smart decisions about vaccines.

Fortunately, this is still a very small, although very vocal, minority of people, as most parents vaccinate and protect their kids.

What to Know About Anti-Vaccine Intelligence and Education

Parents who choose to skip or delay their child’s vaccines are not making smart decisions about vaccines.

The Strategic Plan to Develop a Universal Influenza Vaccine

Even before you get to talk about problems with flu vaccine effectiveness, it becomes clear that everyone wants a better flu vaccine.

One big problem with the current generation of flu vaccines?

You have to get them each and every year.

Developing a Better Flu Vaccine

So what would we all want in a new and better flu vaccine?

It would:

last longer, so you didn’t have to get a new vaccine every year
be more effective
cover more flu vaccine strains, so it wasn’t a “guess” about which flu strains to include in the flu vaccine each year and we didn’t have to worry about drifted flu vaccine strains or new and emerging strains for which there is no vaccine

A universal flu vaccine, which covers all possible flu strains, would be ideal.

So why haven’t we been working on developing a universal flu vaccine?

Well, we have.

It just isn’t that easy.

Many different research teams have been working on a universal flu vaccine for years and some have already had some success.

Does that mean we will see a universal flu vaccine soon?

Unfortunately, of the almost 40 organizations working on improved flu vaccines, including a universal flu vaccine, about 30 are still in preclinical or phase 1 trials. So the answer is no, we will not see a universal flu vaccine soon.

The Strategic Plan to Develop a Universal Influenza Vaccine

Maybe that will change now that more and more folks are pushing for a better flu vaccine and we see the effects of severe flu seasons without a good vaccine.

Of course, talk isn’t enough.

“A priority for the National Institute of Allergy and Infectious Diseases (NIAID) is development of an influenza vaccine providing durable protection against multiple influenza strains, including those that may cause a pandemic, i.e., a universal influenza vaccine. To invigorate research efforts, NIAID developed a strategic plan focused on knowledge gaps in three major research areas, as well as additional resources required to ensure progress towards a universal influenza vaccine. NIAID will use this plan as a foundation for future investments in influenza research and will support and coordinate a consortium of multidisciplinary scientists focused on accelerating progress towards this goal.”

Erbelding et al on A Universal Influenza Vaccine: The Strategic Plan for the National Institute of Allergy and Infectious Diseases

That’s why it is also encouraging that we have seen the:

the Pathway to a Universal Influenza Vaccine workshop convened by the National Institute of Allergy and Infectious Diseases (NIAID) in 2017
the Strategic Plan for Developing a Universal Influenza Vaccine by the NIAID that was announced in 2018
U.S. Sen. Ed Markey (D-MA) introduced the Flu Vaccine Act, which would invest $1 billion towards development of a universal flu vaccine

Knowing that developing a universal flu vaccine is a priority of the NIAID and that so many organizations are already working towards this goal is very reassuring.

Hopefully we are a lot closer than some folks thing.

Until then, a seasonal flu vaccine is the best way to avoid the flu and serious flu complications.

What to Know About Developing a Universal Influenza Vaccine

Developing a better flu vaccine, including a universal flu vaccine, is an even bigger priority with the announcement of the Strategic Plan for Developing a Universal Influenza Vaccine.

Hierarchy of Evidence and Vaccine Papers

Evidence is evidence, right?

Nope.

There is a hierarchy of evidence, from weakest to strongest, that help folks make decisions about science and medicine.

That’s why you can’t just search Google or PubMed, read abstracts, and say that you have done your research.

Hierarchy of Evidence

For any study, you have to review and judge the quality of the evidence it provides.

A meta-analysis with over 1.2 million kids found that vaccines were not associated with autism, while Wakefield's retracted case series included only 12 children. — A meta-analysis with over 1.2 million kids found that vaccines were not associated with autism, while Wakefield’s retracted case series included only 12 children.

Is it a case report (a glorified anecdote), case series, or animal study (lowest quality evidence)?

Or a systemic review or meta-analyses (highest quality evidence)?

“The first and earliest principle of evidence-based medicine indicated that a hierarchy of evidence exists. Not all evidence is the same. This principle became well known in the early 1990s as practising physicians learnt basic clinical epidemiology skills and started to appraise and apply evidence to their practice. Since evidence was described as a hierarchy, a compelling rationale for a pyramid was made.”

Murad et al. on the New Evidence Pyramid

What about case control studies, cohort studies, and randomized controlled trials?

They lie somewhere in between on the hierarchy of evidence scale or pyramid.

And there are other factors to consider when judging the reliability of a study.

“Ultimately, the interpretation of the medical literature requires not only the understanding of the strengths and limitations of different study designs but also an appreciation for the circumstances in which the traditional hierarchy does not apply and integration of complementary information derived from various study designs is needed.”

Ho et al. on Evaluating the Evidence

For example, you might also have to take into account the sample size of the study.

A study can be underpowered if it doesn’t have enough subjects. Unfortunately, even an underpowered study will give you results. They likely won’t be statistically significant results, but folks don’t always realize that.

Even a meta-analysis, usually considered to be at the top of the hierarchy of evidence pyramid, can have problems that make their results less useful, such as not using appropriate inclusion criteria when selecting studies and leaving out important studies.

All in all, there are many factors to look at when reading a medical paper and considering if the results are valid and should influence what you do and how you think. This is especially true when looking at low quality vaccine papers, many of which the anti-vaccine movement uses to scare people, even though they are often poorly designed, and several of which have been retracted.

What to Know About the Hierarchy of Evidence

Learning about the hierarchy of evidence can help you better evaluate medical studies and vaccine papers and understand that there is more to doing your research about vaccines than searching PubMed and reading abstracts.

How to Claim a Vaccine Exemption

Don’t want to get your kids vaccinated?

You might be surprised to know that no one is out there trying to force you into vaccinating them.

Want to enroll your kids in daycare, preschool, school, or college?

Then they will need to be vaccinated.

How to Claim a Vaccine Exemption

Of course, depending on where you live, you could get a vaccine exemption and leave your kids unvaccinated and unprotected.

Does your child qualify for a medical exemption? All states allow kids to claim medical exemptions to getting vaccinated. True medical exemptions are rare though, as you can see from the rates in states that actually require screening and approval of medical vaccine exemptions.

Are you a Christian Scientist? In 47 states, laws allow religious exemptions to vaccinations. Ironically, these exemptions are often abused, as you don’t actually need to belong to a religion that is against vaccines to claim a religious exemption to vaccinations.

“When you are challenged by the viewpoint of a denomination, pastor, publication, or atheist authority: You do not worship any pastor, church, religious publication, or denomination. Your pastor’s personal view on vaccines is irrelevant to your stance because pastors do not learn about the biblical implications of vaccinating during seminary and your pastor isn’t God. (Though if you have a pastor willing to go to bat for you, use him.)”

Megan on How To Get a Vaccine Religious Exemption Like a Boss

It is not even a secret that parents abuse the religious vaccine exemption, claiming them even when they don’t have a sincere religious belief against getting vaccinated.

And in 20 states, it is even easier to claim a vaccine exemption. These are the states that allow philosophical or personal belief vaccine exemptions, in which you can typically just say that you are against vaccinating and protecting your kids “for reasons of conscience.”

Vaccine exemptions are too easy to get in some states, but even with an exemption, your child will still be excluded if there is an outbreak.

What reasons? You don’t usually have to go into much detail…

Why Parents Abuse Vaccine Exemptions

It is not hard to understand why some parents abuse vaccine exemptions.

They abuse vaccine exemptions because they can.

In many states, it is easy to abuse vaccine exemptions because medical exemptions aren’t verified and approved and it is often easier and more convenient to get an exemption than to get vaccinated. Believe it or not, some doctors will even sell you a medical exemption for your child. Also, parents are made to feel so scared by anti-vaccine propaganda that they think that they need to get an exemption.

“Permitting personal belief exemptions and easily granting exemptions are associated with higher and increasing nonmedical US exemption rates. State policies granting personal belief exemptions and states that easily grant exemptions are associated with increased pertussis incidence.”

Omer et al on Nonmedical exemptions to school immunization requirements: secular trends and association of state policies with pertussis incidence.

But just because you can claim an easy exemption in a state without strong vaccine exemption laws doesn’t mean that you should.

While there are no benefits to delaying or skipping vaccines, there are plenty of risks. And the risks aren’t just to your unvaccinated child. We continue to see and hear about kids who are too young to be vaccinated or who couldn’t be vaccinated getting caught up in outbreaks caused by others who simply chose to not get vaccinated.

“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

Not surprisingly, websites and organizations that give advice on getting kids easy vaccine exemptions never mention these risks. They also overstate the risks of vaccines and don’t mention the benefits of getting vaccinated.

Vaccines are safe and necessary. Unless your child has a true medical contraindication to getting one or more vaccines, do a little more research before getting a non-medical exemption.

What to Know About Claiming a Vaccine Exemption

While it is typically not hard to claim a vaccine exemption for your child, since vaccines are safe and necessary, be sure you understand the risks of delaying or skipping any vaccines if your child doesn’t need a true medical exemption.

Using Pubmed to Do Research About Vaccines

A lot of the vaccine research that folks do is on PubMed.

Using PubMed to Do Research About Vaccines

And that’s not necessarily a bad thing.

“PubMed comprises more than 27 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.”

All of the studies that say that vaccines are safe, that vaccines work, and that vaccines are necessary are in PubMed.

So are the studies that show that vaccines are not associated with autism, SIDS, and other so-called vaccine induced diseases, like ASIA.

Unfortunately, there are also poorly done studies in PubMed that do purport that vaccines are associated with autism and that ASIA is a real thing.

Can You Use PubMed to Do Research About Vaccines?

Kelly Brogan didn't make history in getting a case report published in a low impact journal who's editorial board includes a Reiki Master, chiropractors, and naturopaths. — Kelly Brogan didn’t make history in getting a case report published in a low impact journal who’s editorial board includes a Reiki Master, chiropractors, and naturopaths.

Just like anyone can put up a website or Facebook page and say whatever they want, almost anyone can get a study or article published in a journal and get it indexed in PubMed.

While PubMed is an index with over 27 million citations, it doesn’t do anything to evaluate those citations to see if they include studies with design flaws, conflicts of interest, or are simply fraudulent.

That means that you need to know that a study does not get a badge of legitimacy for simply being in PubMed!

And it does not automatically mean that the evidence and conclusions from the article are of high quality just because it is listed in PubMed.

So use PubMed to find articles to help you do research about vaccines, but then read the article from beginning to end, not just the abstract, and make sure it is an article you can trust:

Was it published in a legitimate journal, like Vaccine or Pediatrics, and some of these high-impact journals? (good)
Was it published in a predatory journals? (bad)
Does it involve simply looking at VAERS data? (usually bad)
Is it written by folks with a conflict of interest that makes the article biased? (bad)
Has it already been refuted by other people because it wasn’t designed properly or had other major flaws? (bad)
Is it written by people who have expertise on the topic they are writing about? (good)
Has it been retracted? (very bad)
Is it a case report (a glorified anecdote), case series, or animal study (lowest quality evidence) or a systemic review or meta analyses (highest quality evidence)?
Is it a case control study, cohort study, and randomized controlled trial, which lie somewhere in between case reports and reviews on the hierarchy of evidence scale?

Are you ready to get educated about vaccines?

That’s great, but PubMed shouldn’t be your first stop, or your only stop.

As you do your research or get bombarded with a list of links or abstracts from PubMed, remember that there is a hierarchy of evidence to consider before deciding if a paper or study is really evidence of anything. And finding a case report, study on rats, or an invitro study won’t win you an argument about vaccines when there are randomized control trials and systemic reviews on the other side.

What to Know About Using PubMed to Do Research About Vaccines

PubMed is a giant index of journal articles, but simply being in PubMed doesn’t mean that an article or study is reliable or of high quality, whether it is about vaccines, a vaccine-preventable disease, or any other medical topic.
