I'm prob wrong but isn't the reason to delay the Pfizer 2nd jab until week 12 a strategic one from the UK Gov't rather than a supply one. My understanding was that they the gov't think that there will be greater impact to give more people the first jab rather than fewer people both jabs? According to some docs however, there is no evidence that the first jab lasts effectively more than the first 3 weeks (as that wasn't trialled) - they have only trialled it as the 2nd jab coming after 3 weeks for the protection they have quoted. Therefore the danger is that lots of people will be going around feeling safe after the 1st jab for up to 12 weeks whilst in actuality being potentially vulnerable (and of course, with their confidence raised, more prone to taking risks and spreading the virus).
Not sure if my understanding is right there. Happy to be corrected! Hope all here are well
