Re: Coronavirus
There's not enough detail here on the 2022 boosters - will they be the same formulation as the current vaccine or a new spike sequence to cover any variants? It would be smart to cover your bases and allow a 'new and improved' vaccine to come through now the principle has been proved.
Clearly the current vaccines are 'leaky', allowing infections and even severe disease in a very small number of cases so improvements could potentially be made.
