I am not an MD, so I’ll offer just this: it’s very encouraging to see federal regulators take swift action on the J&J vaccine. This is the process working as it should. If there is a true link between the vaccine and these rare clots, they will work to identify it. 1/

They may instate an age restriction, as some countries have done for the similar AstraZeneca vaccine—perhaps younger people, especially younger people who are biologically female, may end up needing to seek an alternative. But for now: these cases appear VERY RARE. 2/

So far less than 1 in 1 million. And this DOES NOT detract from the effectiveness of the vaccine, which is excellent.

If you have gotten this vaccine, keep those numbers in mind. All clots also appeared within 2 weeks of injection. 3/

I hope we come out of this more knowledgeable. But this is a setback. A vaccine this convenient was a boon for incarcerated communities and low resource settings. What’s next? 4/4
