In the study, protection against Covid was seen from about 14 days after vaccination, with similar levels of protection regardless of age of cases or contacts, PHE was quoted as saying in a statement.
‘Experts urge people to continue to take up vaccination and maintain Covid appropriate behaviors, as vaccines are vital in helping us return to a normal way of life.’
The protection was in addition to the reduced risk of a vaccinated person developing symptomatic infection in the first place, which is around 60 to 65 percent — four weeks after one dose of either vaccine, the BBC report said.
“Vaccines are vital in helping us return to a normal way of life. Not only do vaccines reduce the severity of illness and prevent hundreds of deaths every day, we now see they also have an additional impact on reducing the chance of passing Covid-19 on to others,” Dr Mary Ramsay, head of immunization at PHE, was quoted as saying.
The study, which has yet to be fully peer-reviewed, included more than 57,000 contacts from 24,000 households in which there was a lab-confirmed coronavirus case that had received a vaccination, compared with nearly one million contacts of unvaccinated cases. The findings showed households are among the most likely places for infection to spread, the report said.
While the findings are significant, the experts urged people to continue to take up vaccination and maintain Covid appropriate behaviors.
