Unfortunately what is going on with the J&J vaccine is not a good look. It now gives people something to point to in order to say, "see, I told you they rushed the vaccines and didn't test them." Never mind the fact that if these blood clots are related to the vaccine, a one in a million reaction is highly unlikely to be encountered in the normal course of a vaccine approval.
Since these reactions only occurred in women, I wonder if they were taking birth control and there was some kind of interaction.
As to the comment by
@seascape above, I would agree that if there have been no similar cases among men, they could probably continue to administer to men and pause women. I wouldn't want to make it age based among women. First of all, a huge majority of women over 60 have been vaccinated already anyway. For the remaining who want to be, there are plenty of Moderna and Pfizer doses available. Second, the reaction has been so rare that it is possible it could occur in older women but hasn't been encountered yet.
