Coronavirus clinical trials data have always shown that vaccines have greatly reduced the risk of developing symptoms of the coronavirus.

But the association between vaccination and reduced asymptomatic infections remained unclear.

When the Pfizer-BioNTech jab was authorized for use in the US, it proved to be effective at preventing COVID-19. Trial data indicated that it significantly reduced symptomatic disease as a result of the virus, including hospitalization and mortality.

According to a research letter in the Journal of the American Medical Association, vaccination dramatically reduced both COVID-19 symptomatic and asymptomatic infections in St. Jude Children's Research Hospital employees compared with their unvaccinated peers.

The study is one of the first to show an association between COVID-19 vaccination and fewer asymptomatic infections.

Additionally, according to CNN Arabia, there is a 90 percent reduction in asymptomatic infections as well, which is similar to the rate of decrease of symptomatic infections.
