US FDA is recommending a pause in the use of the J&J #covid19 vaccine while they investigate 6 reported cases of the kind of rare clotting disorder seen after AZ vaccine too.
Should not come as a huge surprise to those of you who have been following the reporting on this. https://twitter.com/US_FDA/status/1381925612743499778">https://twitter.com/US_FDA/st...

As @GretchenVogel1 and I wrote last week, EMA is already investigating this safety signal.
Given that this vaccine (like AZ one) too uses an adenovirus to deliver the genetic instructions for #SARSCoV2 spike protein, there were worries about this.

There will be a press conference at 10am ET that may have more information.
But for now, think of this as a cautious approach to a safety signal, similar to what, for instance, PEI in Germany did when reports of AZ side effects emerged almost exactly a month ago.

The numbers:
As of April 12, more than 6,8 million doses of the vaccine have been administered in the US.
So far there are six reported cases of CVST with thrombocytopenia, all were were "women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination."
