> I remember doctors and media denying AstraZeneca Blood cloths for months, before they added to the official adverse reaction list, finally. 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.
