Two doses of Pfizer or Oxford vaccine reduce risk of transmission by more than half, study shows


Two doses of the Pfizer or Oxford vaccine reduces the risk of passing on COVID by more than half, a new study shows.

Researchers in Scotland found that people living with health workers who had been given one dose of a coronavirus vaccine were 30% less likely to get it themselves.

The same study found that households of health workers who had received both doses were 54% less likely to contract the virus.

The findings are the first in the UK to provide direct evidence that COVID-19 vaccines not only prevent severe disease and death – but also transmission.
