A month after testing positive for COVID-19, a group of people with mild infections had protective antibodies in their blood, a new study has found.
The study, whose findings should be interpreted with caution as it has not yet been peer-reviewed or published in a medical journal, followed a group of 160 hospital staff in France who had tested positive for COVID-19 but did not require hospitalization.
The researchers found that nearly all the patients had measurable amounts of antibodies — material produced by the body as it fights off an infection – and that these antibodies were somewhat able to neutralize the virus.
