A new study suggests that COVID-19 antibodies may protect against redefinition for at least 6 months

A recent study published Wednesday in the New England Journal of Medicine suggests that antibodies could protect people who have already had COVID-19 from being re-infected for at least six months.

Researchers looked at 12,541 healthcare workers at Oxford University Hospitals in the United Kingdom and were followed for up to 31 weeks.

In the study, researchers investigated cases of COVID-19 infection by conducting polymerase chain reaction (PCR) tests on the healthcare workers who had tested positive and negative, including symptomatic and asymptomatic cases.

The results of the study showed that 11,364 did not have antibody levels, and 1,265 had positive results, which also included 88 healthcare workers in whom seroconversion occurred during the follow-up period. A total of 223 anti-spike-negative healthcare workers received a positive PCR test (1.09 per 10,000 days at risk), up to 100 were found to be disproportionate at screening, and 123 to have symptoms, the study found.

Researchers reported that individuals with anti-pig antibodies had no symptomatic infections.
