Tbh I think the real problem with the EU program originated from the moment Macron rubbished the Astra Zeneca jab for the over 65s when the peer reviewed science said no such thing. There was a lack of trial data but the overwhelming likelihood was always that it would still be hugely beneficial, a weaker immune reaction is expected, but worse scenario was that it wouldn't fall off a cliff and be useless, as he all but implied.
The technical issues they now face with storing unused AZ vaccines combined with the normal logistical problems of having enough extreme cold temperature storage facilities for the Pfizer tells a predictable story. Combine this with the comfort he gave to the head the ball anti vaxers and the increase in vaccine scepticism across France and now Europe, and you have your cocktail for the new mutant variants to thrive.
The South African and Brazilian variants are even more dangerous than the Kent variant, and levels of the Brazilian and South African ones are now reaching dangerous tipping points of 10% of all infections across 10 of their regions, and up to 50% in one or two.
Top scientists in Germany and Italy have called for a complete rethink of strategy, widespread vaccination of the vulnerable groups with all available jabs and a stretching of the gap between first and second doses is urgently being looked at. France has Macron to contend with.
