The FDA has said it investigated the blood clot/low platelets cases after J&J vaccine & found no causal association with the vaccine: they're continuing to investigate. https://www.abc.net.au/news/2021-04-10/johnson-and-johnson-covid-vaccine-eu-review-over-blood-clots/100060722 Given the way the EMA's statement of formal investigation is being reported,...1/4

..I went back to EMA press conference to check my tweets. Peter Arlett from EMA said: (at ~40 mins) Since the trial "There have been 3 cases with the J&J vaccine of blood clots associated with low platelets which have some similarities to these cases...2/4

...that we’ve been describing today for AstraZeneca vaccine. However the numbers are extremely small compared to the 4.5 million patients vaccinees that have received the J&J vaccine worldwide.” (~51 mins) "…if you look at those reports of blood clots with thrombocytopenia...3/4

...for those other vaccines & then compare them to the background rates we would expect to see, they are not raised.”

So it's 1 in the original 1-dose trial, 3 post-marketing in the US. None reported from the 2-dose trial or from South Africa. Rate not higher-than-expected
