COVID-19: the vast majority of patients with a minor form develop neutralizing antibodies

Teams from Strasbourg University Hospital and the Institut Pasteur carried out a study among hospital staff on the two sites of Strasbourg University Hospital. After observing 160 people with minor forms of COVID-19, the scientists concluded that nearly all the patients developed antibodies within two weeks of being infected. In 98% of the patients, neutralizing antibodies were detected after 28 days. This suggests that even those with minor forms of the disease develop antibodies that could confer immunity for several weeks following infection. The results were presented in a pre-publication on the MedRxiv website.
