Review | Prevention of host-to-host transmission by SARS-CoV-2 vaccines.

Study ties COVID vaccines to lower transmission rates.

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”.

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

Covid-19 vaccination prevents transmission from vaccinated to unvaccinated household members.
