COVID Reinfections Clear Faster, Including in Unvaccinated People: Study

Reinfections cleared faster than initial COVID-19 infections, including among people who never received a COVID-19 vaccine, according to a new study.

People infected with COVID-19 for a second time cleared the illness a mean of 6.6 days, compared with a mean of 9.3 days for the initial infection, U.S. and British researchers reported in the paper.

Researchers drew the findings from 1,796 first infections and 193 second infections.
