Results of two recent studies show that antibodies the human body produces in response to COVID-19 infection make it very unlikely a person will be reinfected with the virus for as long as six months and possibly longer.

According to Dr. Ned Sharpless, director of the National Cancer Institute, a study conducted by the organization showed that protection provided by previous infection "is strong and comparable to the protection afforded by effective SARS-CoV-2 vaccines."

The study analyzed data from 3 million antibody tests and found that within a follow-up period that lasted a maximum of 120 days, fewer than 1% of people who had antibodies tested positive for active COVID-19 infection.

Sharpless told Fox News that "reinfection is very, very rare."

Researchers in England conducted the other study, which involved health care workers. Among the 1,265 who had antibodies at the time of testing, only two were diagnosed with active COVID-19 infection during the following six months. Of the 11,364 who did not have antibodies, 223 did test positive for coronavirus infection in the follow-up time period.
