The World Is Waiting?

Nobody will be entirely free of Sars-CoV-2, until the whole world is vaccinated! This was the primary reason the Covax scheme was set up. Its aim was to bring vaccine more quickly to poorer nations, who could not easily pay the pharmaceutical companies. It was intended, that the Oxford/AstraZeneca vaccine would play a large initial part in Covax. This vaccine sharing scheme is not, however, currently going well (https://www.theguardian.com/world/2021/apr/22/revealed-big-shortfall-in-covax-covid-vaccine-sharing-scheme). Only 20% of the Oxford/AstraZeneca doses, expected by May, have been delivered in Covax participating countries. The shortfall is due to a combination of export bans (such as that recently imposed in India), hoarding (in some cases, by countries not actually using the vaccine, because of safety concerns) and supply shortages (sometimes the amount of vaccine produced by particular plants has been less than predicted). The result is that countries like Brazil and Indonesia have received only 10% of their promised doses. Countries such as Bangladesh, Mexico, Myanmar and Pakistan have had zilch (nothing). The longer people in these countries go unvaccinated, the more time the virus has to mutate in their people. It is also (even with quarantine) next to impossible, to stop new mutants reaching other countries (including those with high vaccination rates).
