Johnson & Johnson says coronavirus vaccine prevents extreme sickness in hamsters
J&J researchers vaccinated hamsters with a single dose after which uncovered the rodents to the virus 4 weeks later, the corporate mentioned.

Vaccinated hamsters additionally appeared to lose much less weight than unvaccinated hamsters and did not expertise extreme scientific illness, similar to pneumonia, or mortality. The outcomes had been revealed Thursday within the medical journal Nature Drugs.
“This pre-clinical examine additional validates our confidence in our SARS-CoV-2 vaccine candidate,” J&J’s Chief Scientific Officer Paul Stoffels mentioned in a press launch. “With our Section three trials deliberate to begin this month, we stay dedicated to increasing our manufacturing and distribution capabilities to allow international entry to our SARS-CoV-2 vaccine candidate ought to it show to be protected and efficient in people.”
The promising ends in hamsters don’t essentially imply the vaccine will present the identical degree of safety in people. However J&J researchers famous the findings are necessary as Covid-19 is understood to progress into extreme illness in some people.
