Now.. maybe it is still worth the risk for a young 20 year old female, but I am not so sure - especially since we luckily have other vaccines that do not show this risk.
If this vaccine is causing at most 4 deaths per million people* vs 648 recorded US covid deaths 15-24 out of a population of 43.5 million. 4 * 43.5 = ~174 < 648. So, it would have been noticeably safer for a random 20 year old American to have taken it Jan 2020 than risk covid. https://knoema.com/atlas/United-States-of-America/topics/Dem...
So if the total future infections are say 1/4 the total infections up to this point then their roughly equivalent risks. Tipping one way or the other based on actual number of infections.
* It’s rare enough that actual risks aren’t clear, but assuming the vaccine is the cause we can assume the risks are at or below that level.
