PEOPLE VACCINATED AGAINST COVID-19 MAY BE LESS CONTAGIOUS

People who get a COVID-19 vaccine can still become infected with the novel coronavirus, although they are likely to be protected against severe illness, and a new study suggests they also may be less contagious. At a large Israeli health organization where 650,000 members received the two-dose vaccine from Pfizer and BioNTech, researchers identified 2,897 patients who later tested positive for COVID-19. The amounts of virus on swab samples were reduced fourfold for infections occurring at least 12 days after the first dose compared to what is typically seen in unvaccinated COVID-19 patients, the research team found.
