The light at the end of the tunnel is growing brighter.
Emergency-use approval for a third COVID-19 vaccine (from Johnson & Johnson) is now secured, and four million doses have immediately shipped. Over 200 million doses of the Pfizer-BioNTech and Moderna vaccines are expected by month-end, and 50 million doses of the AstraZeneca-Oxford vaccine (which is expected be approved next month) should follow by the end of April. The day when anyone can get a COVID vaccine is now within view. It’s already time to start worrying about the next set of problems, from inadequate uptake by vaccine-resistant communities to ensuring poorer countries get adequate supplies of the vaccine, so that we can truly put this pandemic to an end.
