Dr. Robert Sears vaccine info misleads parents about measles

robert sears vaccine

Dr. Robert Sears vaccine info is false and misleading. On January 16, 2015, Sears, who refers to himself as Dr. Bob, is a California pediatrician and author of a controversial book on vaccines (critiqued here, pdf, or here by the fine folks at Science-Based Medicine).

He wrote in his Dr. Bob’s Daily and published on his Facebook page that measles is only rarely fatal in developed countries and that serious complications are rare. (In the likely event that Dr. Sears decides to delete his misleading comments, it’s archived here permanently.) 

And they were irresponsible. In a way that can put people – including children, including his patients – at serious risk. This is not the first time Dr. Bob Sears has made inaccurate claims about a vaccine-preventable disease, but on the background of the current measles outbreaks, the risk from his behavior is more imminent and more obvious. It is appropriate to react. Continue reading “Dr. Robert Sears vaccine info misleads parents about measles”

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”

German government backs mandatory measles vaccine – anti-vaxxers weep

Good news for those of us who want to stop vaccine-preventable diseases – the German government has backed a bill for a mandatory measles vaccine for all children entering school or kindergarten. I’m sure the science-denying anti-vaccine crowd in Germany are angry

If the German parliament approves the bill, which is almost certain, parents will have to provide evidence that their child has received the measles vaccine before they are enrolled in school. If the parents have failed to do so, they will be subject to fines up to €2,500 ($2,800).

If this bill is passed, Germany will join France and Italy as the other European countries with a mandatory vaccines law. Many other European countries have such high vaccination rates that they have little need for mandatory measles vaccine, but I’m sure they are watching carefully considering the rather large measles epidemic that has hit Europe over the past year. 

The USA does not have a Federal mandatory measles vaccine law, but all 50 states and the District of Columbia require children to be fully vaccinated (according to the CDC immunization schedule, which includes the MMR vaccine for measles, mumps, and rubella) before entering school. However, many states allow so-called “personal belief exemptions,” which allow parents to easily skip some or all vaccines based on whatever they want.

As a result, some states have either implemented or are considering strict laws to make certain that children entering school are fully vaccinated. California, Maine, New York, Washington, Mississippi, and West Virginia have mostly eliminated personal belief exemptions, only allowing medical exemptions, where the child has some contraindications to some vaccines. The German law also does the same – it only allows medical exemptions.

The German state of Brandenburg recently passed its own law instituting a mandatory measles vaccine for children entering kindergarten. The state government was concerned about Brandenburg’s relatively low measles vaccination rate, 72.5%, far below the 92.9% rate for the whole country.

The German government was motivated to consider a law because of pockets of anti-vaccine parents (like in the USA) along with Europe’s aforementioned measles epidemic. According to the European Centre for Disease Prevention and Control,  Germany has reported 429 measles cases for 2019 through June 14.
 
This bears repeating. The measles is easily prevented by a vaccine.
 

A quick measles primer

Measles (also called rubeola, not to be confused with rubella, or German measles, which despite its name, isn’t the issue in Germany) is a respiratory disease caused by the measles virus. Measles virus normally grows in the cells that line the back of the throat and lungs.

The virus is spread through respiration (contact with fluids from an infected person’s nose and mouth, either directly or through aerosol transmission), and is highly contagious — 90% of people without immunity sharing living space with an infected person will catch it.

There are no specific treatments for the disease. There are no miracle preventions.

The oft-repeated, and highly inaccurate, claim that vitamin A supplements can cure or prevent measles completely misses the mark. It’s important to supplement with vitamin A to prevent blindness as a result of measles, but it doesn’t reduce mortality or prevent some neurological issues. Moreover, it is most useful in children with vitamin A deficiency, not exactly a major issue in well-fed children in developed countries.

Why do we need mandatory measles vaccine?

Which leads me to remind everyone that measles is not a harmless disease, despite the false claims of the anti-vaccine religion. According to the CDC, some of the many measles complications are:

  • About 30% of measles cases develop one or more complications.
  • Pneumonia, which is the complication that is most often the cause of death in young children.
  • Ear infections occur in about 1 in 10 measles cases and permanent loss of hearing can result.
  • Diarrhea is reported in about 8% of cases.
  • As many as 1 out of every 20 children with measles gets pneumonia.
  • About 1 child in every 1,000 who get measles will develop encephalitis, an inflammation of the brain that can lead to convulsions, deafness, and other long-term neurological deficits.
  • A measles infection can result in short- and long-term immune system dysfunction which can leave the child susceptible to other diseases early in life (which is in direct opposition of claims by anti-vaccine activists that it helps “boost” the immune system.
  • About 1-2 children, out of 1000 who contract measles, may develop subacute sclerosing panencephalitis (SSPE), a rare chronic, progressive encephalitis that affects primarily children and young adults– it is caused by a persistent infection of the measles virusThe disease starts with measles infection, usually before the age of 2 years, followed by approximately 6-15 asymptomatic years. Some researchers think the asymptomatic period is around 5-8 years after the initial disease. Gradually, the disease progresses with psychological and neurological deterioration, which can include personality changes, seizures, and coma. It is always ultimately fatal.
  • And sadly, for every 1,000 children who get measles, 1 or 2 will die from it.

These measles complications are more common among children under 5 years of age and adults over 20 years old (usually those with lapsed immunity).

Even in previously healthy children, measles can be a serious illness requiring hospitalization. Measles also can make a pregnant woman have a miscarriage, give birth prematurely, or have a low-birth-weight baby.

There is only one good way to prevent measles unless you want your child to live in a hermetically-sealed bubble forever – get the MMR vaccine.

Serious complications to measles can be as high as 3 out of every 10 children who get the disease. Serious complications from the MMR vaccine is approximately 1 out of every 1 million vaccine doses. The benefit to risk calculation is way over on the side of vaccines.

Summary

Measles is a dangerous, highly contagious disease that can permanently harm or even kill healthy children. It is not a disease that should be ignored.

The German mandatory measles vaccine law is what needs to be done to protect the children of the country. It is great that Germany is taking this step – I’m sure other countries will do the same.

Vaccines save lives. And the German government knows this and is moving to make sure every child is protected.

 

Predicting US measles outbreak – vaccine uptake and international travel

The locations of the current US measles outbreak (or epidemic) was predicted by researchers in an article recently published in Lancet Infectious Diseases. The amazingly prescient predictions were not based on magic, but on a scientific analysis of two factors – the vaccination rate and international travel tendencies by county in the United States.

And the statistical website, Five Thirty-Eight, took the predictions and listed out what happened during this US measles outbreak. The predictions were spot on.

Time to look at this study and its predicted results.

New York ends vaccine religious exemptions – protecting us from measles

vaccine religious exemptions

Sometimes, there’s excellent news with the fight to end vaccine-preventable diseases. On 13 June 2019, Governor Andrew M. Cuomo (see Note 1) signed a bill whereby the state of New York ended vaccine religious exemptions.

As a result of this new law, New York joins California, Arizona, Mississippi (yes, Mississippi), West Virginia (ditto), and Maine as the only states that do not allow religious exemptions, that is, allowing parents to claim that their religious beliefs are not compatible with vaccinations.

Since there are no mainstream religions that are opposed to vaccines, I have always found that this type of exemption was bogus and an excuse for parents to formalize their pseudoscientific beliefs. This put children at risk of dangerous and deadly vaccine-preventable diseases.

For New York, the removal of the religious exemption is critical. The center of the current US measles epidemic, which has struck over 1000 individuals, seems to be in the ultra-orthodox Jewish population in the state who have abused the exemptions. This gave us an unvaccinated population, concentrated in a small area, that was susceptible to a highly contagious and dangerous disease.

Anti-vaccine nutjobs, like Jim Meehan and Del Bigtree, using disgusting tropes like claiming that mandatory vaccinations are like the Holocaust, have tried to fan the flames of the anti-vaccine dogma by making the religious exemptions to vaccination as some religious liberty issue.

Of course, the legislative process to get this bill passed was not easy. According to an article in the New York Times:

The tension over the issue was readily apparent in the Capitol on Thursday as hundreds of angry opponents — many with young children and infants — pleaded with lawmakers to reject the bill, sometimes invoking the will of God, other times their rights as parents. The show of raw emotion affected even supporters of the bill.

Assemblyman Michael Montesano, a Long Island Republican, framed the bill as “an attack on people’s First Amendment rights.” He added, “It’s still the individual parent, who is raising this child, that has the fundamental right to decide what happens with their child in all facets of their life.”

As the vote came to a head, emotions were high:

As the Assembly vote slowly came in, the speaker, Carl E. Heastie, was forced to come to the floor and count votes, calling recalcitrant members to coax the bill toward the 76-vote threshold needed for passage. Several prominent Democrats, including the chairman of the health committee, Richard N. Gottfried, bucked Assembly leadership and voted no. In the end, it narrowly passed, 77 to 53.

As soon the vote count was called, shouts of “shame” — and more colorful invective — erupted from the Assembly gallery, where opponents had gathered to watch the proceedings. Assemblyman Jeffrion L. Aubry attempted to restore order, but the screams continued; unable to stop the shouting, Mr. Aubry took the chamber into recess as furious opponents headed into Capitol hallways.

The only shame that I see are recalcitrant legislators not voting to protect the health of children.

Nevertheless, the pro-science, pro-children, pro-health side won. And Governor Cuomo signed it into law.

This is how we stop the measles epidemic and save the lives of innocent children. Vaccines save lives.  So thanks – New York eliminates vaccine religious exemptions!

Notes

  1. When I was in graduate school, studying real biomedical science as opposed to anti-vaccine pseudoscience, I was a canvasser for Governor Cuomo’s father, Mario Cuomo who was subsequently elected governor of New York. Thus, I was 0.000047% responsible for this bill. You can thank me by buying me a beer.

Maine vaccine exemption bill – eliminates all non-medical exemptions

maine vaccine exemptions

As a result of the ongoing measles epidemic, a lot of states are restricting or removing non-medical vaccine exemptions. Recently, the Maine vaccine exemption bill was signed into law. It eliminates all personal belief exemptions for children attending school, though it still allows for medical exemptions.

Professor Dorit Rubinstein Reiss recently wrote about the new Maine vaccine exemption bill. She described that the Maine House initially approved the bill, but added back religious exemptions which are abused by anti-vaccine parentsno mainstream religion in the world is opposed to vaccines

Eventually, the Maine House agreed to the language in the Senate version, which eliminated religious exemptions, and it was sent to Maine’s Governor Janet Mills, who signed it into law on 24 May 2019.

The Maine vaccine exemption bill is similar to strong pro-vaccine laws in California, Mississippi, and West Virginia that limit so-called “personal belief exemptions,” that is, vaccine exemptions that are for any reason other than medical contraindications.

The bill’s sponsor, Democratic Maine House Representative Ryan Tipping, said:

As we hear more reports of measles and other preventable diseases in Maine and across the country, it has become clear that we must act to ensure the health of our communities.

The abuse of these personal belief exemptions has led to a decrease in vaccination rates, which brings the rate below the level necessary to maintain herd immunity – that is, a sufficiently high enough percentage of individuals who have been vaccinated that prevent the disease from spreading to unvaccinated individuals.  

Opponents of this law are promising a court fight as they have done in California (and losing every single time). They are trying to present an argument that removing religious exemptions are an infringement of “religious liberty.” However, numerous Supreme Court decisions, such as Prince v Massachusetts and Jacobson v Massachusetts, give the state quite a bit of latitude to protect its citizens and, especially, its children.

According to another article by Professor Reiss,

Our immunization jurisprudence gives states substantial leeway to protect the public health via vaccination requirements, specifically, in this context, by allowing states to decide whether, and under what conditions, to exempt students from school immunization requirements. But states have to actually use that power to achieve anything. By leaving the floor to the passionate, if passionately wrong, anti-vaccine minority, we are allowing them to undermine the right of the rest of us to be free from preventable diseases.

In other words, the “religious liberty” argument is extremely weak, especially, as I mentioned above, there are no mainstream religions that oppose vaccines. In fact, most strong support them because they protect the lives of children.

At any rate, let’s congratulate Maine for strengthening vaccine laws. And for keeping religion out of a medical decision. Irony intended.

Vaxxed producer Del Bigtree – not credible on vaccines

Over the past few months, Vaxxed producer Del Bigtree, who formerly worked on the show The Doctors, has made numerous statements about vaccines and vaccine safety. His claims about fraud by the CDC have been addressed in the past, and the evidence doesn’t support his beliefs. But the claims he makes about vaccines go beyond the movie, and he makes an effort to present himself as an authority on the issue.

Mr. Bigtree’s statements are consistently inaccurate, suggesting he is not a good source of information about vaccines. It’s impossible to address every single wrong claim Mr. Bigtree has made about vaccines, of course. But these problems should demonstrate that Mr. Bigtree’s claims about vaccines cannot be relied on.

Testing vaccines for cancer – another anti-vaxxer myth with no credibility

testing vaccines

If you’re spending more than a nanosecond reading idiotic memes from the anti-vaccine religion, I’m sure you’d see the old the package insert says that FDA doesn’t require testing vaccines to determine whether they cause cancer or not. It still makes me laugh how much authority the anti-vaxxers give to package inserts, but that’s another story for another day.

Oh wait, it is another story that I told. You know, the old argument by vaccine package insert fallacy. It’s a fun one, it’s helpful in dismissing the bogus claims that the anti-vaxxers make using package inserts.

Like all zombie memes from the vaccine deniers, this one keeps disappearing then returning every few months. And now with the current measles epidemic in the US and other areas, it’s arisen from the graveyard of debunked vaccine myths to haunt the internet. 

And it’s time to debunk it once again. Continue reading “Testing vaccines for cancer – another anti-vaxxer myth with no credibility”

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.

2019 measles epidemic still going strong – the MMR vaccine stops it

2019 measles epidemic

As of 10 May 2019, the CDC has reported 839 cases in the 2019 measles epidemic – the vast majority of these individuals were unvaccinated. As a result, this year is the worst for measles in the USA since 1994, just prior to the startup of the Vaccines for Children Program (VCP) that provides free vaccines to US children.

VCP was passed into law as a consequence of another measles epidemic, from  1989-91, that resulted in over 55,000 reported cases of measles, 11,000 measles-related hospitalization, and 123 deaths. It’s amazing what vaccines can do. Continue reading “2019 measles epidemic still going strong – the MMR vaccine stops it”
