COVID-19 vaccines and myocarditis – what are the facts

Regulatory agencies, such as the FDA and CDC, are monitoring reports of myocarditis, a heart inflammation, after COVID-19 vaccines. Although if there is a link, it is exceedingly rare, anti-vaccine activists have already on this issue to make it appear that COVID-19 vaccines are dangerous.

My job is to look at this data and give you a scientific analysis of the observations and whether they are actually related to the vaccine.

Like with reports of other conditions, such as blood clots, after receiving COVID-19 vaccines, we need to examine whether myocarditis is actually related to the vaccine or just random events in which the incidence is no different than what would be predicted in a similar group of unvaccinated people. And if it is linked, we need to look at the potential risk and compare it to the risks of COVID-19 itself.

Why can’t we get a cancer vaccine as fast as one for COVID-19?

cancer vaccine

I keep reading memes and other nonsense that if scientists are so smart why can’t we have a cancer vaccine as fast as we did for COVID-19? It’s not a serious question, it’s actually pejorative – it’s meant to imply that we’ve been looking for years for a cancer vaccine without success, yet we were able to get a COVID-19 vaccine within a few months, so obviously it was rushed.

Fortunately for us on the side of science, this is one of the silliest and most desperate myths being pushed by our favorite anti-vaxxers.

Busting cancer myths is one of my favorite activities – my non-statistical analysis of medical pseudoscience puts cancer slightly above vaccines on the stupidity of the tropes. Combining vaccine nonsense with cancer is right up my bailiwick. Let’s have some tearing apart this trope.

COVID vaccine breakthrough infections – let’s do some simple math

Let’s talk about COVID-19 vaccine breakthrough infections. That is individuals who contract COVID-19 despite being fully vaccinated by the Pfizer, Moderna, or JNJ vaccines, the only ones with Emergency Use Authorizations in the USA.

This article is going to be short and, hopefully, sweet, because even though the number of COVID-19 vaccine breakthrough infections appear large, it really isn’t. It’s just simple math.

Myocarditis and COVID vaccine – a rare event that may not be linked

COVID-19 vaccine myocarditis

Regulatory agencies across the world, including the FDA and CDC, are monitoring COVID-19 vaccine adverse events including reports of myocarditis, a heart inflammation. Of course, the anti-vaccine squad will probably jump on this to make it appear that the vaccine is dangerous.

My job is to look at this data and give you a scientific analysis of the observations and whether they are actually related to the vaccine.

Like with reports of other conditions, such as blood clots, after receiving COVID-19 vaccines, we need to examine whether this adverse event is related to the vaccine or just random events in which the incidence is no different than what would be predicted in a similar group of unvaccinated people.

COVID herd immunity – vaccine denial may make that impossible

The only way to COVID-19 herd immunity is going to be via vaccines, but people throughout the world, especially in the USA, are refusing the COVID-19 vaccine. The anti-vaccine world is doing everything it can to sow fear, uncertainty, and doubt about these vaccines, despite our efforts to counter the disinformation campaign.

Let’s talk about COVID-19 herd immunity and how vaccines are important. And why we probably can’t hit herd immunity, a terrible consequence of the anti-vaccine rhetoric and lies.

COVID-19 vaccine shedding – another anti-vaccine myth to scare people

COVID-19 vaccine shedding

Here we go again – an expensive, privileged Miami private school has banned teachers who received the COVID-19 vaccine because of “shedding” concerns. Yes, you read that right, the school wrote to teachers that “we cannot allow recently vaccinated people to be near our students until more information is known.”

The school’s co-founder, Leila Centner, claimed that those people who had received the COVID-19 vaccine can somehow shed the spike protein, which in turn can cause menstrual cycle irregularities, miscarriages, and sterility in other women just by being in close proximity to vaccinated people who are shedding something.

Centner wrote, “we cannot allow recently vaccinated people to be near our students until more information is known.” She must get this nonsense from Kelly Brogan, anti-vaccine quack, who seems to have something with Centner and this school

Centner cited debunked claims that the vaccine causes infertility based on “reports have surfaced recently of non-vaccinated people being negatively impacted by interacting with people who have been vaccinated. Let’s be clear that that the scientific consensus about this vaccine is that is very effective and carries few risks.

Simply put, COVID-19 vaccine shedding does not exist, but I will spend a few moments debunking it again.

COVID-19 vaccine during pregnancy – the CDC now recommends it

pregnancy COVID-19 vaccine

The CDC just announced that it recommends the COVID-19 vaccine during pregnancy to protect the health of the mother and the developing fetus. The CDC stated that there are “no safety concerns” among women in their third trimester and for their newborn babies.

Despite the claims of COVID-19 deniers everywhere, the disease is dangerous and can cause both short- and long-term harm to anyone, and that means pregnant persons and their newborn babies. That’s why the COVID-19 vaccine is so important.

Let’s take a look at what the CDC said and why pregnant persons should get the COVID-19 vaccine.

COVID-19 vaccines herd immunity – ignore anti-vaxxer disinformation

The only way to herd immunity to this pandemic is with COVID-19 vaccines, but still, people are refusing the vaccine, not only in the USA but also throughout the world. But the anti-vaccine world is doing everything it can to sow fear, uncertainty, and doubt about these vaccines.

Herd immunity is a form of indirect protection from infectious diseases that can occur when a sufficient percentage of a population has become immune to an infection, by vaccines or infection, which reduces the risk of infection by members of the community who lack that immunity. Although we don’t have a solid estimate for herd immunity levels for COVID-19, it is estimated to be between 60 and 75%.

Without herd immunity, there are a number of consequences. People who cannot get vaccinated or are immunocompromised will always be at risk of contracting the disease. The virus will continue to be transmitted, which will lead to more dangerous mutations. And there are local outbreaks of COVID-19 across the world that could bring the disease back to the USA and many other countries where we don’t reach herd immunity.

A large group of COVID-19 deniers and anti-vaxxers want to create herd immunity “naturally” instead of using vaccines – that is essentially genocide since so many people will die or suffer long-term consequences.

We need to get the COVID-19 vaccines into as many people as we can so that we can reach herd immunity. Right now, about 25% of Americans may refuse to get the vaccine, and that means we probably cannot reach herd immunity.

mbedThis article is just a list of my articles that can be useful in your arguments with the anti-vaxxers and individuals who are “on-the-fence.”

COVID vaccine updates – large clinical trials will be unnecessary

covid vaccine updates

The questions I keep getting are will we need COVID-19 vaccine updates and how fast could we get them. These are important questions going forward, especially since there are some dangerous variants that seem to be spreading widely.

I think we should look at the model for flu vaccines – each year the antigens are targeted by the vaccine are changed slightly to improve effectiveness. Admittedly, with the flu vaccine, it’s hard to do since the influenza virus can mutate rapidly.

However, regulatory agencies worldwide do not require massive clinical trials for the new formulations, as long as nothing else changes except for the antigens. That’s the model that we will probably require for future COVID-19 vaccine updates in the future.

Vaccine effectiveness – correcting misunderstandings about COVID-19 vaccines

vaccine effectiveness

I keep reading how people think that when a COVID-19 vaccine is reported to have 95% effectiveness it must mean that they have a 5% chance of catching COVID-19 after being vaccinated. But effectiveness doesn’t quite mean that, and I wanted to clarify.

Part of the reason this needs clarification is that until we have herd immunity against COVID-19 (along with all of the variants), it’s important to practice all of the public health measures like wearing a mask and social distancing even if you have been vaccinated.

So, this will be a little bit of mathematical analysis of vaccine effectiveness, so that you know what it means.
