Exactly, all Pfizer have said is that they have assessed the efficacy of the immunisation at their recommended time span, not at the maximum of 12 weeks. Just they say it will not give 100% immunity, they will give a time scale for each inoculation and not move from it for legality reasons. As the system gets up and running and onto 24 hr coverage if the supply chain is adapted to cope with it, common sense dictates that the time span between 1st and 2 nd shots will come down.. I am not for one minute denying that we are in a sticky situation at the moment, but **** me there are so many people who want to put a negative spin on every positive advancement in tackling this situation
