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.
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.
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).
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.
