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.
