A comment on Myocarditis associated with Covid-19 compared to mRNA vaccines. Parent comment
29.1.2021: EU approval for the vaccine is granted
~10.3.2021: first countries pause usage, EMA officially starts investigating.
18.3.2021: risk of blood clots is added to list of known potential side effects
so not even 2 months.
EDIT: and to pre-empt hair-splitting which list counts:
7.4.2021: moved from "potential side effect" to "known side effect". ~ 2 months and a week.
