COVID causes “substantial” long-term cardiovascular risks

This cohort study compared cardiovascular disease risk after COVID-19 infection to those who had never contracted the disease.

Adverse events surveillance after 11.8 million COVID mRNA vaccine doses

A paper was just published that reviewed adverse events after 11.8 million COVID-19 mRNA vaccine doses were administered in the USA. Because it is the topic of discussion these days, I felt it was important to review this paper.

Even though anti-vaxxers love to claim excess adverse events after people receive the COVID-19 mRNA vaccine, there are excellent methods that the CDC has developed to monitor these issues in vaccines, and this new paper looks at one of them.

The news is good, in case you’re wondering.

Athletes are not collapsing after getting any of the COVID vaccines

I’ve noticed that anti-vaccine activists are pushing a trope that athletes are collapsing on the field after getting one of the COVID-19 vaccines. I watch a lot of sports and read a lot of sports news, so if this were really happening, I would have noticed.

I have to pick and choose which dumb anti-vaccine myths I need to debunk. But since I love sports and I know that the COVID vaccines are safe and effective, I thought I’d look into it. And what I found was, as you might expect, nothing. It’s just one of those myths that anti-vaxxers make appear as factual but isn’t.

Let’s take a look at this silly myth.

Paper claiming COVID vaccines and myocarditis link is RETRACTED

An anti-vaccine group run by the discredited James Lyon-Weiler tried to show that the COVID-19 vaccines are linked to myocarditis in a vain attempt to discredit them. The paper they published was just retracted. Of course.

Ironically, when the paper was published last week, I was going to write about it. However, it lasted about a week before Retraction Watch reported that the publisher retracted it. So, I’ll write about how this is a terrible article and why it got retracted (actually, the publisher isn’t being transparent, so we really don’t know).

Anti-vaxxers misuse VAERS against COVID-19 vaccines – bad science

Recently, a poorly written pre-print article uses VAERS “data” to show that the COVID-19 vaccines cause myocarditis in children 12-17 years old. Although we do have some data that the COVID-19 mRNA vaccines may be linked to myocarditis in some age groups.

I, and many others, have frequently criticized the use of VAERS, and I will do it again in this article, so just hang on. It cannot be used for anything by gross observations, and it certainly cannot be used as the basis for an article that condemns a vaccine.

So, let’s once again go down the rabbit hole of misusing VAERS to evaluate the safety of COVID-19 vaccines.

Myocarditis and COVID mRNA vaccines – very rare adverse event

Regulatory agencies, such as the FDA and CDC, are monitoring reports of myocarditis, a heart inflammation, after COVID-19 mRNA vaccines from Moderna and Pfizer. Although myocarditis after these vaccines are exceedingly rare, anti-vaccine activists have already jumped 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.

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

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.
