The online argument about this is raging about whether this is a stupid decision and I’d like to side step that well-trodden path of vitriol to ask more broadly: what’s the deal with Covid and blood clotting? I know personally a long hauler who has blood clotting issues and low platelets. They fall into the demographic of concern with the JJ and AZ vaccine. Anecdotally we have lost both a close relative and a young and healthy friend to Covid blood clotting related issues. Again, I’m not weighing in on the FDA’s job. But just saying: as someone who’s anecdotally been hyper-aware of the blood related aspects of Covid, this thread has picked up my ears and I’m really interested in finding out what the linkage here is.
