$BNTX It has already been proven by the example of countries with a very high rate of vaccination - Portugal, Malta, etc. - that there will be no such thing as "group immunity" that some people used to say. In other words, quite contrary to what the WHO has had enough to say..., even if everyone is vaccinated in the world, Covid19 will continue to be active... - and annual booster doses will be needed, and probably for a few years yet.
