For once I completely disagree with the WHO (for what it is worth) about Vaccine Nationalism, urging UK to halt or slow vaccination so that the rest of the world will catch up. As the burden of recorded case in the world is dominated by countries like US, UK Brazil and Mexico and France accounting for 60% of the total world cases, I think that it is a matter of urgency that these countries should go ahead full steam with vaccination to stem the number of cases and deaths and in turn also limit new mutations. Admittedly the problem with the data is that the true situation is probably not known in a lot of Africa, but I see no reason why for example Vietnam or Thailand or New Zealand, where the urgency to vaccinate is much less, should not wait.
