On my way to my dialysis treatment I began to listen to this week's Skeptics' Guide to the Universe (epidose 822, dated April 10, 2021). I should point out that usually they record on Wednesdays (though Dr. Novella edits the recording then posts it on the following Saturday), so some of the following info is over a week old and might be passed by more recent news.
They began with COVID-19 news specifically on the AstraZenica (AZ) vaccine (which I will again point out is not given in the US [yet], only in Europe). Dr. Novella noted that one of the blood clotting problems beyond DVT that was found was CVST. Like with the J&J shot all of the AZ recipients who had CVST were female. Unlike with the J&J shot, all of those who had CVST were under 55 years old and there was more than one death. These cases are still very rare compared to the overall population who have gotten the AZ shot and there is a proposal in some countries to limit the new recipients to those who are 55 and older, but the damage has been done: people have begun to refuse the AZ shot even when no alternate shot was available. Again, the odds for death by CVST when taking the AZ vaccine are vanishingly small compared to dying from COVID-19, but humans are very bad at assessing risks. Heh, I just watched tonight's
Colbert Report Late Show and Colbert featured an "interview" with a woman (likely a staff member) who complained about the news reporting on the links between CVST and the J&J shot. She pointed out that the odds for a woman to get very serious side-effects from any of the birth control drugs are much, MUCH greater than the odds for that same woman to suffer from CVST due to the J&J shot, but which story gets the headlines now?
This is very problematic because unlike all the other vaccines the AZ vaccine does not require any refrigeration. It was hoped that having a much longer shelf light that the AZ shot could be distributed in poorer countries, many of which--especially in remoter locations--could not provide the required refrigeration for those other vaccines.
