High Level Of Exposure To Covid Virus Can Reduce Protection From Vaccination: Study

According to PTI, the study was conducted to learn if the immunity achieved after getting vaccinated, and having a prior infection turns out to be less effective in case the people are exposed to high levels of the virus.

The study in question tracked infections among 15,444 residents of Connecticut correctional facilities. The research was conducted between June 2021 and May 2022, when the state was exposed to the Delta and Omicron variants of COVID-19.

One of the researchers also stated that it is really hard to find a population group like the Connecticut Department of Correction, where one knows the type of exposure somebody has and the status of their vaccination and prior infection.
