Moderna vaccine worked well in monkeys: Study

Moderna's experimental COVID-19 vaccine worked in monkeys and prevented the virus from replicating in their noses and lungs, according to a study published in the New England Journal of Medicine.

Scientists said monkeys who received even a low-dosage vaccine produced more antibodies than people who had recovered from the virus, and it appeared to stimulate an immune response from so-called T-cells.

The study also found that two days after the vaccinated monkeys were exposed to the coronavirus through the nose and directly to the lungs, no replicating virus was found in the lungs of seven of the eight animals.
