COVID-19 vaccines and blood clots – a review of current science

COVID-19 vaccines blood clots

There have been extremely rare reports about blood clots being related to the JNJ and AstraZeneca COVID vaccines. Although science does not why this happens, researchers continue to explore why these COVID-19 vaccines might be linked to blood clots (thrombus).

A new review of the current research clears up some of the mystery, but, unfortunately, opens up some new questions. This article will examine the science, at least as far as we know, behind these blood clots and the two COVID-19 vaccines.

COVID vaccines effectiveness against new Delta variant

COVID vaccines effectiveness Delta

With the spread of the Delta variant (known as B.1.617.2 by the CDC) from India, scientists have been concerned about the effectiveness of COVID vaccines against it. The good news is that the Pfizer and AstraZeneca vaccines seem to fairly effective against this new variant of SARS-CoV-2 virus.

Let’s take a look at the paper that describes the effectiveness of the vaccines against the COVID-19 Delta variant.

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 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-19 vaccine blood clots – the FDA and EMA are doing the right thing

COVID-19 vaccine blood clots

If you have been watching the COVID-19 vaccine roll-out, you know that blood clots have become a concern with the vaccines from JNJ (Johnson & Johnson-Janssen) and AstraZeneca. Shockingly, some pro-vaccine types are trying to dismiss these concerns by posting ridiculous memes that try to compare blood clots from these vaccines to ones from birth control pills or smoking.

Setting aside the fact that memes are for the intellectually and scientifically weak, such as anti-vaxxers, these memes are trying to compare apples to bowling balls. Furthermore, ignoring these potential links play right into the hands of the anti-vaccine crowd.

mbedIn my not-so-humble opinion, the US FDA, European Medicines Agency (EMA), and other health agencies across the world have done the right thing by “pausing,” or limiting the use of the vaccines from JNJ and AstraZeneca. Science has been doing the right thing with regards to the COVID-19 vaccine blood clots issue.

JNJ COVID-19 vaccine and blood clots – still safe and effective

jaj COVID-19 vaccine clots

Like the earlier story about the AstraZeneca COVID-19 vaccine and blood clots, the JNJ (Johnson and Johnson) vaccine is being examined for a potential link to an extremely rare blood clotting disorder. The US Food and Drug Administration and the CDC have placed a “pause” on the use of the vaccine. They have not banned it. They have not recalled it.

Right at the top, I want to state that the JNJ COVID-19 vaccine is safe and effective by any rational measurement. My daughters and their significant others all received the vaccine over the weekend after I recommended it, despite the blood clots issue.

I want to review what is happening here. I hope that it helps, in some small way, to allay the fears from this issue.

Is the AstraZeneca COVID-19 vaccine linked to blood clots? EMA provides guidance

astrazeneca COVID-19 vaccine blood clots

I have previously written about whether thrombosis (formation of blood clots) is linked to the AstraZeneca COVID-19 vaccine – my conclusions were that they probably weren’t. However, governments and the European Medicines Agency (EMA) are starting to get me very concerned about an issue with this vaccine.

Recently, the government of Quebec recently decided that the AstraZeneca vaccine will only be used on individuals 55 years and older. Of course, this caused some parts of the anti-vaccine world to froth at the mouth claiming the vaccine isn’t safe.

Then, on 6 April 2021, the European Medicines Agency (EMA) is reporting a plausible link between the AstraZeneca vaccine and thrombotic events. I will discuss this in detail below.

I think that many of the adverse events that are claimed to be associated with any of the COVID-19 vaccines involve the post hoc ergo propter hoc fallacy, which states that because one event precedes another event, they must be linked. It is entirely possible that thrombosis occurs after vaccinations because of random chance rather than actual correlation (let alone causation). However, thrombosis that is temporally associated with the AstraZeneca vaccine may be troubling.

Because the AstraZeneca COVID-19 vaccine is one of the four main vaccines (along with those from Pfizer, Moderna, and JNJ) to be given in the USA, Canada, the EU, Australia, and New Zealand, I want to make sure that the potential of a causal link to blood clots are given a thorough analysis.

AstraZeneca COVID-19 vaccine and thrombosis – should we worry?

AstraZeneca COVID-19 vaccine thrombosis

I have previously written about whether thrombosis (formation of blood clots) is linked to the AstraZeneca COVID-19 vaccine – my conclusion was that they probably weren’t. But still, there are nagging anecdotes and government decisions that may concern those of you who are looking to get the vaccine.

Recently, the government of Quebec recently decided that the AstraZeneca vaccine will only be used on individuals 55 years and older. Of course, this caused some parts of the anti-vaccine world to froth at the mouth claiming the vaccine isn’t safe.

Because the AstraZeneca COVID-19 vaccine is one of the four main vaccines (along with those from Pfizer, Moderna, and JNJ) to be given in the USA, Canada, the EU, Australia, and New Zealand, I want to make sure that the potential of a causal link to thrombosis events are given a thorough analysis. I especially want to focus on why the Government of Quebec decided to make this change – and it’s a lot more complicated than the narratives pushed by the anti-vaccine crowd.

AstraZeneca COVID-19 vaccine safety and efficacy – no reason to refuse it

AstraZeneca COVID-19 vaccine safety

I have been noting with alarm that the safety and effectiveness of the AstraZeneca COVID-19 vaccine – it’s concerning people, and sometimes governments, are refusing the vaccine. This is wrong.

My girlfriend, an ER physician who is literally exhausted from saving lives during this pandemic, wrote this recently:

So many lives have been lost to COVID-19. Please vaccinate.

I may write picky things about these vaccines, just to follow the science, but in the end, I don’t care which COVID-19 vaccine I received and you shouldn’t either. The AstraZeneca vaccine is demonstrably safe and demonstrably effective.

I have made an effort to push the facts and debunk the myths about all of the COVID-19 vaccines. I think the AstraZeneca one needs
