Study shows 1st dose of vaccine reduces transmission.
Quote:
A single dose of a coronavirus vaccine can reduce household transmission of the virus by up to half, a study shows.
Those given a first dose of either the Pfizer or AstraZeneca vaccines - and who became infected three weeks later - were between 38% and 49% less likely to pass the virus on than unvaccinated people, PHE found.
