We've had the first case of blood clotting today from the AZ vaccine. While insignificant in number, doesn't do much for public confidence.
Considering its basically the only vaccine we have signed up for (minus a small amount of Pfizer), TGA will be under huge pressure reverse its backing. Lots of european countries have limited its use in under 60s. We dont have that choice, i do think public uptake would be higher if another vaccines were offered
