A study has found that an antibody drug produced by Regeneron Pharmaceuticals has reduced the risk of developing symptomatic Covid-19 by up t0 81%. According to the company, there were no hospitalisations of Covid-19 volunteers within the study, compared with four in the placebo group. The Wall Street Journal reports that the study has also shown the drug’s ability to reduce the risk of death or hospitalisation by about 70%. “So far, 21.3% of the U.S. population has been fully vaccinated, and 35.3% has received at least one shot”. Regeneron’s president, George D. Yancopoulos, has said the antibody cocktail may “help provide immediate protection to unvaccinated people who are exposed to the virus.”– Jarryd Neves
