Protection was even greater for people who completed two doses. A week or more after receiving the second dose, vaccinated individuals were 96 per cent less likely than unvaccinated people to become infected with SARS-CoV-2. When researchers looked just at asymptomatic infections, vaccination reduced the risk by 90 per cent, according to a research letter that appears in the Journal of the American Medical Association. Pfizer COVID-19 Vaccine Likely to be Approved by US FDA For 12-15 Year Age Group Next Week.

“While further research is needed, by preventing infections, including in people who have no symptoms, there is a high possibility that vaccination will decrease transmission of SARS-CoV-2,” said Diego Hijano, from the St. Jude Department of Infectious Diseases. The study involved 5,217 St. Jude employees who were eligible under Tennessee state guidelines for vaccination between December 17, 2020, and March 20, 2021.
