Isolated cases of re-infection with Covid-19, the disease caused by the SARS-CoV-2 virus, had raised concerns that immunity might be short-lived and that recovered patients may swiftly fall sick again. “Being infected with Covid-19 does offer protection against re-infection for most people for at least six months,” Eyre said. During the study, 89 of 11,052 staff without antibodies developed a new infection with symptoms, while none of the 1,246 staff with antibodies developed a symptomatic infection. Staff with antibodies were also less likely to test positive for Covid-19 without symptoms, the researchers said, with 76 without antibodies testing positive, compared to only three with antibodies. Those three were all well and did not develop Covid-19 symptoms, they added.
