I'd have to look back - but, from memory it was 2 injections - then, - ??? maybe 3 years later for a booster
I assume it's for life - if one is in at risk areas - I'm not totally sure on that though.
I wouldn't concentrate on the 6 months thing with Covid - we don't know yet how it's going to pan out after the 3rd shot - the booster.
My guess is that we will know a lot more in about 2 to 3 years after we've had it somewhat endemic - and, after many cases have had covid 2 or 3 times - that's going to tell us a lot - and, that's one process we just cannot speed up.
Of course - in that time - technology will go ahead in leaps and bounds also - there's some feverish research into the new technology going on.
