Also, if the effected group is only young women, the denominator isn't really the same as the total number vaccinated. Not saying it isn't still very rare, but in young people COVID deaths are also very rare. We have alternative vaccines, it makes perfect sense to advise young women against J&J for the time being while this is sorted out. And for anyone that thinks this is just normal incidence of blood clots being blamed on the vaccine - that's what was said about AstraZeneca originally, and if these clots are anything like those it is absolutely not the case. Those are serious clots that are very rare to see period, let alone in young people, and require different treatment than normal clots (they have surprisingly low platelet count). I suspect US agencies had good reason to want to pause J&J given all of that - the AZ vaccine issues were also disproportionately affecting women interestingly.
