According to a new study, Covid-19 transmission drops by at least 30% after vaccination.
Public Health Scotland and the University of Glasgow examined 300,000 NHS workers between December 8 – the first day of vaccination in Scotland – and March 3.
The researchers looked at the records of people living with both vaccinated and unvaccinated health care workers and found that those who had a single dose were at least 30% less likely to pass on the virus.
Given that people who live with health care workers could catch the virus from other sources as well, researchers say the 30% figure is a low estimate.
It was found that those who received both doses of the vaccine were at least 54% less likely to pass on the virus.
