'Short-changed' on Vaccines by G7?

Different European countries are opening up social activities, as their Covid19 infection rates fall. There is concomittantly a debate about whether the UK risks another winter wave of infections, by sticking to its road-mapped 'freedom day' on the 21st of June. Perhaps more important, is a rather overlooked outcome from the G7 meeting in Cornwall (https://www.theguardian.com/world/2021/jun/13/lifting-covid-rules-could-mean-repeat-of-winter-wave-of-cases-says-sage-adviser). Everyone is aware that nobody is safe from Sars-CoV-2 and its variants, until the entire world is vaccinated. The G7 were informed that 11 bn vaccines were needed to treat people in the poorest countries. They collectively pledged 1bn. The G7 were also told that the costs of this vaccination programme would be $50bn. They committed $5bn. As yet unknown variants, are likely to develop in unprotected parts of the world. The G7's very limited offers, could well come back to bite it.
