Natural immunity – more vaccine denier pseudoscience with no merit

natural immunity

“Natural immunity” is the trope du jour of the anti-vaccine world – they want us to believe that contracting a dangerous pathogen is somehow better than preventing that disease with a vaccine. Their pseudoscientific beliefs rely upon logical fallacies, a complete misunderstanding of how the immune system works, and a healthy dose of bad math.

In other words, the same old same old from our anti-vaxxer “friends.”

The purpose of this article is to discuss why natural immunity is a bogus concept when it comes to vaccines. I need to make one warning upfront – immunology is complicated and cannot be described in 1000 words or less. So, I’m going to do a lot of linking to good articles that describe various things about the immune system.

But here we go – hang on for some science. Continue reading “Natural immunity – more vaccine denier pseudoscience with no merit”

MSG in vaccines – is it another evil chemical causing harm or not?

There are so many random claims from the anti-vaccine activists about evil chemicals in your child’s vaccines. Aluminum in vaccines is dangerous? No. Mercury in vaccines? No. Formaldehyde in vaccines is killing our kids? Nope. And of course, MSG in vaccines is causing something. 

Of course, many of you have heard about MSG in our food. It’s up there on the evil food chemical list along with aspartame, high fructose corn syrup, GMO‘s, and whatever else is the food danger of the day. But MSG certainly has been on the top of the “avoid” list for decades.

I’ve been refuting nonsense about chemicals for at least 25 years on the internet (back before we had social media, yeah I’m an old dinosaur). From my perspective, I think that 50% of the issues with “chemicals” is their long complex names. And the other 50% is because of the appeal to nature logical fallacy, which is the argument that natural substances are somehow superior to “chemicals.” 

Ironically, everything in nature is a chemical, and unless you think everything in the universe is designed for human health (ridiculous), a “natural” chemical is not even close to being superior to a “man-made” chemical. 

But let’s get back to MSG – how many times have you seen “No MSG” in a sign Chinese restaurant? So if we don’t want to put MSG in our kung pao chicken, then why would we want MSG in vaccines? 

What we’re going to show in this article is that MSG dangers are a myth. And the dangers of MSG in vaccines is a bigger myth.

Yes, vaccine herd immunity works – scientific evidence supports this fact

herd immunity

This piece is a summary of Herd Immunity and Immunization Policy: The Importance of Accuracy, published in v. 94 of the Oregon Law Review.

As a bit of background, in an article that was published in the Oregon Law Review in 2014, authors Mary Holland and Chase E Zachary claimed that school immunization mandates are inappropriate because they reject the concept that herd immunity works.

This article will explain why Holland and Zachary’s analysis or immunization mandates and herd effect is simply incorrect. And let’s be clear – there is a legitimate debate about whether school immunization mandates are appropriate, policy-wise, as a response to non-vaccination.

Unlike vaccine science, the appropriate policy to handle non-immunization is not agreed upon, and the data on what is the right way to get people to vaccinate is anything but clear (though some things are clear – for example, harder to get exemptions lead to higher vaccination rates). But the debate needs to be premised on accurate facts – not on misuse of legal terms and incorrect scientific data. Holland and Zachary’s article does not provide that.

Vaccination informed consent – more anti-vaccine rhetoric from ICAN

In a misleading “White Paper,” the anti-vaccine organization, Informed Consent Action Network (ICAN) argued that “eliminating vaccine exemptions and curtailing criticism is unethical and un-American” because, they argue, it invalidates vaccination informed consent. The initial statement is wrong, and the arguments brought to support it are wrong. This article corrects the record.

Chickenpox and shingles – same virus, different vaccines

chickenpox and shingles

There are a lot of nuanced facts and evidence about vaccines. The so-called “pro-vaccine” crowd looks at the body of evidence, then concludes that it saves children’s lives by stopping vaccine-preventable diseases. The “anti-vaccine” side seems to rely on anecdotes, cherry picking bad studies published in really bad journals, and read anti-science websites, just to support their preconceived conclusions. And now there is a lot of junk science with respect to chickenpox and shingles, much of which we need to refute and debunk.

One of the enduring myths of the antivaccine cult is that chickenpox vaccine will increase the rate of shingles, especially in older adults. A published article examines chickenpox and shingles vaccines – and like everything in science, it’s the nuanced data that makes the story. Not the headlines.

Shingles increase heart attacks – time for the vaccine

Shingles increase heart attacks

Shingles, a reactivated form of the chickenpox virus, is a painful rash that afflicts many people decades after the initial chickenpox infection. Now, we have data that shingles increase heart attacks (myocardial infarction) and strokes. This is more evidence that we need to end chickenpox with the chickenpox vaccine, and reduce the risk of shingles in those who have had chickenpox with the shingles vaccine.

Let’s take a look at shingles and this new study. Continue reading “Shingles increase heart attacks – time for the vaccine”

Vaccines prevented 200 million cases of disease in the USA from 1963 to 2015

vaccines prevented

Lest we forget, vaccines are one of the greatest medical inventions of all time. Without them, we would see cemeteries filled with children who would have died before they were even five years old.  In fact, the best evidence we have tells us that vaccines prevented 200 million cases of diseases in the USA alone in the five decades since 1963.

A recent study, published in AIMS Public Health, estimates that around 200 million cases of polio, mumps, rubella, measles, adenovirus, hepatitis A and rabies have been prevented in the U.S. from 1963 through 2015 as a result of widespread vaccination. The study, authored by Leonard Hayflick and S. Jay Olshansky, two leading experts on public health and infectious diseases, also discloses that about 450,000 deaths have been avoided in the U.S during this period, although other studies put that estimate of lives saved at a much higher number.

Dr. Hayflick discovered the human cell strain, WI-38, in 1962 which was critical to the safe manufacturing of vaccines, which became widespread in 1963. According to the article, the vaccines produced from the WI-38 cell line prevented almost 4.5 billion occurrences of the diseases, and stopped them from returning to infect us. Dr. Hayflick developed the foundation that allowed the world to have relative safe and very effective tools to prevent infectious diseases.

Prior to the development of WI-38, anti-virus vaccines were grown in monkey cells, which had some issues that made many question their safety, although most of the concern appeared to be overblown. However, once the WI-38 was available, it became easier to develop and produce vaccines for many viruses.

Drs. Hayflick and Olshansky wanted to see what effect that seminal event had on public health. And the numbers were incredible. Continue reading “Vaccines prevented 200 million cases of disease in the USA from 1963 to 2015”

Adult vaccines – the CDC wants to save adult lives too

adult vaccines

Generally, when I write about vaccines, it’s about protecting children’s lives from vaccine preventable diseases. That itself is a noble goal for vaccines. But in case you didn’t know, there is also a CDC schedule for adult vaccines, which is as important to adults as they are to children.

Vaccines have one purpose – to protect us and those whom we love from potentially deadly and debilitating diseases. Many of us in the blogosphere have talked about the children’s schedule a lot, often to debunk claims of people who are ignorant of science, and think that the children’s vaccine schedule is causing undue harm. Yeah our intellectually deficient president, Donald Trump, thinks he knows more than the CDC, but that’s a problem shared by many vaccine deniers.

One adult vaccine I push regularly is the flu vaccine. It protects adults, pregnant women, the elderly, children, and healthy young adults from a severe infection that hospitalizes and kills more people every year than you’d think. Because flu is not really a serious disease, in some people’s minds, a lot of people decide that they don’t need the vaccine. They’d be wrong.

Just in case you were wondering, there is more to adult vaccines than just flu vaccines. There are several other vaccines indicated for adult use, including those adults with underlying health issues like diabetes, HIV and heart disease – unfortunately, the uptake for adult vaccines is depressingly low. Let’s take at the low uptake and the recommended adult vaccines schedule.

Varicella vaccine effectiveness – more supporting evidence

varicella vaccine effectiveness

The varicella vaccination for chickenpox was introduced in the mid-1990’s in the USA and has been associated with substantial and statistically significant declines in incidencehospitalizations and deaths attributable to chickenpox. Thanks to  real science, more evidence supports varicella vaccine effectiveness.

Despite the beliefs of vaccine refusers, who have stated emphatically that chickenpox is not dangerous, the real complications from a varicella infection are numerous and serious:

  • dehydration
  • pneumonia
  • bleeding problems
  • infection or inflammation of the brain (encephalitis, cerebellar ataxia)
  • bacterial infections of the skin and soft tissues in children including Group A streptococcal infections
  • blood stream infections (sepsis)
  • toxic shock syndrome
  • bone infections
  • joint infections

Since I was born before the chicken pox vaccine, I contracted the disease, which eventually lead to encephalitis. I have vivid memories of being a five year old child and being admitted into the ER with a brain infection. It’s a memory I’d rather not have.

The anti-vaccine gang love to question the effectiveness of vaccines. But they don’t have evidence of that, whereas, I’m going to present some powerful evidence that the varicella vaccine is highly effective in preventing chickenpox.

Vaccines saved lives – scientific evidence

There are many canards propagated by the vaccine deniers to support their personal beliefs (really, denialism) about the safety and effectiveness of vaccines. One of their more popular beliefs is that vaccines didn’t end many of the deadly diseases, but improved sanitation, healthcare, nutrition or magical fairies (also known as homeopathy) ended these diseases.

There is even a subgroup of these believers who think that the CDC, historians, and everyone else is lying about the epidemics that existed prior to vaccinations–let’s call this group history deniers. They reject the scientific and historical evidence that vaccines saved lives – amazing.

So, is there scientific evidence that vaccines actually ended these epidemics? Yes there is, and it’s unequivocal. Unless you want to embrace historical revisionism, and somehow all of the health care records and epidemiological information was faked, vaccines saved lives – lots of lives.
