London:
One dose of the Pfizer or AstraZeneca vaccines reduces the possibilities of an individual infected with coronavirus from spreading it to other household members by up to 50 %, according to a English study published Wednesday.
The Public Health England (PHE) study identified that these who became infected 3 weeks soon after getting their initially jab had been among 38 and 49 % significantly less probably to pass the virus on to their household contacts than these who had been unvaccinated.
“This is terrific news — we already know vaccines save lives and this study is the most comprehensive real-world data showing they also cut transmission of this deadly virus,” stated British Health Secretary Matt Hancock.
“It further reinforces that vaccines are the best way out of this pandemic as they protect you and they may prevent you from unknowingly infecting someone in your household,” he added.
The study drew information from more than 57,000 contacts in 24,000 households in which there was a lab-confirmed case that had received a vaccination, compared with practically one million contacts of unvaccinated instances.
Previous research have currently shown that getting vaccinated reduces the threat of a individual building symptomatic infection in the initially spot by up to 65 %, 4 weeks soon after one dose.
Households are deemed as “high-risk” settings for transmission, and “similar results could be expected in other settings with similar transmission risks, such as shared accommodations and prisons,” stated the PHE study.
“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,” stated Mary Ramsay, Head of Immunisation at PHE.
Previous PHE research have estimate that Britain’s succesful vaccine rollout had prevented 10,400 deaths in the more than-60s by the finish of March.
