"Government deal to buy 35m doses of Pfizer booster shots to be delivered next year adds to clouds over the Oxford-AZ jab
Britain may be about to start its Covid booster jab roll-out, but already the wheels are in motion for next year's vaccine blitz. This week, ministers announced they had struck a deal for 35m Pfizer booster shots to be delivered in the second half of 2022.
"While we continue to build this wall of defence from Covid-19, it's also vital we do everything we can to protect the country for the future too – whether that's from the virus as we know it or new variants," Sajid Javid, Health Secretary, said.
Among the scientific community, news of the order raised some eyebrows. By last week, Britain already had more than 500m jab doses on order with eight vaccine makers. Of the vaccines which had been approved here, the UK had ordered more than 210m doses.
"I find it all a little bit disturbing," said Clive Dix, the former interim chair of the vaccine taskforce. "I think it's crazy we're going down that route [to buy doses for 2022] already." In his view, decisions over boosting seem to be rushed.
"I would personally just say let's boost with the AstraZeneca vaccine this year, which we have available and which is a very good vaccine - and only then should we start thinking about next year."

AFAIK - adenovector used in VZ makes it harder to do 3rd shot because immute system can figth off the vector virus and thus reduce effectiveness of that shot.
Delta specific shot is needed anyway
