Covid-19 vaccine worked well in monkeys

Chennai: United States-based biotech firm Moderna’s Covid-19 vaccine induced a robust immune response and prevented the coronavirus from replicating in the noses and lungs of monkeys, a study in the New England Journal of Medicine said.

The vaccine preventing the virus from replicating in the nose is being viewed as particularly crucial in preventing it from being transmitted onward to others.

In the Moderna animal study, three groups of eight rhesus macaques received either a placebo or the vaccine at two different dose levels — 10 micrograms and 100 micrograms.

All vaccinated macaques produced high levels of neutralizing antibodies that attack a part of the SARS-CoV-2 virus used to invade cells, AFP reported.
