One dose of the Pfizer/BioNTech or AstraZeneca/Oxford vaccines reduces the chances of someone infected with the SARS-CoV-2 virus that causes Covid-19 from spreading it to other members of their household by almost half, according to a English study published on April 28 (2021).

The Public Health England (PHE) research found that those who became infected three weeks after receiving their first jab were between 38% and 49% less likely to pass the virus on to their household contacts than those who were unvaccinated.
