A University of Cambridge study revealed that one shot of the Pfizer vaccine did not only prevent developing the illness but also reduced the virus transmission among people by 75 percent.
The study focused on new Covid infections among inoculated health workers and it showed “dramatic” results.
“This is great news – the Pfizer vaccine not only provides protection against becoming ill from SARS-CoV-2 but also helps prevent infection, reducing the potential for the virus to be passed on to others,” Dr. Mike Weekes said.
Among unvaccinated nurses, 56 tested positive for the virus out of 3,282 while only eight contracted the bug out of 1,997 vaccinated nurses.
“This is fantastic news for both hospital staff and patients, who can be reassured that the current mass vaccination strategy is protecting against asymptomatic carriage of the virus in addition to symptomatic disease, thereby making hospitals even safer places to be,” Dr. Nick Jones said.
Molecular Virology Professor Jonathan Ball shared the same feeling: “To see such a reduction in infection rates after a single dose of the Pfizer vaccine is very impressive and shows that vaccination truly does offer a way out of the current restrictions and a much brighter future.”
“It will be important to understand whether the reduced risk of infection played out across all the exposure risk groups included in the study, but nonetheless, this is still excellent news.”
