Effect of Vaccination on Household Transmission of SARS-CoV-2 in England – “the likelihood of household transmission was approximately 40 to 50% lower in households of index patients who had been vaccinated 21 days or more before testing positive than in households of unvaccinated index patients”.
24 Jun, 2021 | 09:52h | UTCRelated: Study in England showed one dose of COVID-19 vaccine can cut household transmission by up to half – This protection is on top of the reduced risk of a vaccinated person developing symptomatic infection, which is around 60 to 65% after the first dose AND Covid-19 vaccination prevents transmission from vaccinated to unvaccinated household members.
