One dosage of a Covid vaccine can almost halve transmission, research study finds

LONDON– A single dosage of a coronavirus vaccine can decrease transmission within a household by up to half, a study by Public Health England has actually found.

Individuals who do end up being infected with the coronavirus 3 weeks after getting a single dosage of the Pfizer-BioNTech or AstraZeneca-University of Oxford vaccine were in between 38% and 49% less most likely to pass the virus on to their household contacts than those who were unvaccinated, the PHE study found.

Security was seen from around 14 days after vaccination, with comparable levels of protection despite age of cases or contacts.

This protection is on top of the minimized risk of an immunized person establishing symptomatic infection in the first place, which is around 60% to 65%– four weeks after one dose of either vaccine, PHE kept in mind. Having both doses of a coronavirus vaccine (the delay between dosages depends on 12 weeks in the U.K.) confers an even higher level of protection versus Covid infection.

The U.K.’s Health Secretary Matt Hancock hailed the study’s findings as “excellent news.” “We currently know vaccines save lives and this study is the most comprehensive real-world data showing they also cut transmission of this deadly virus.”

” It even more strengthens that vaccines are the very best escape of this pandemic as they secure you and they might prevent you from unwittingly contaminating somebody in your home.”

“I advise everybody to get their vaccines as soon as they are eligible and make sure you get your second dose for the greatest possible protection,” he added.
