2 x AZ, 1 x Pfizer last Boxing Day. Contracted Covid over Songkran.
Vaccination not recommended for six months after any Covid infection, so that puts me at October earliest. However I will wait and see what medical advice is ten, and see if there is any improved or updated vaccine for further variants.
But to be honest, if I do have a forth, I don't think I would go for any more after that.
