“a very small ‘percentage’
Just what percentage and how big was the base?
Last I saw, in the US there were 15 reports of blood clots that MAY have been caused by the J&J vaccine and zero deaths known to be caused by the vaccine out of about 7 million shots given. Also, last I saw, all of the people reporting clotting were women. If all the clot reports are actually linked to the J&J vaccine, that would put the overall risk of developing them at about 1 in 467,000.
Important to note that approval hormonal birth control pills for women can result in blood clot issues as often as 1 in 1,000.
