The stopgap before a vaccine

摘要

FOR people who have survived covid-19, there is an opportunity to add another chapter to their recovery story: they could help save other people's lives by donating blood. The plasma of people who have recovered from the disease contains precious antibodies that helped them fight off the virus, and could help others do the same, or even make them temporarily immune. Such antibodies are an increasing focus of research efforts to treat and prevent covid-19. According to senior US health official Anthony Fauci, antibody therapies could be a "bridge to a vaccine" - a stopgap to carry us safely to the promised land.
