ToplinePeople who contract coronavirus are “highly unlikely” to get the virus again for at least six months, according to a new study from the University of Oxford, pointing to a potential breakthrough in research on Covid-19 immunity after more than 57 million people have had coronavirus since the start of the pandemic.
Someone waits to be tested for coronavirus.
The study, a collaboration between the University of Oxford and Oxford University Hospitals NHS Foundation Trust that is yet to be peer-reviewed, evaluated 12,180 health care workers at Oxford University Hospitals for 30 weeks from April to November.
The researchers tested the health care workers for antibodies to see if they had been infected and continued to frequently test staff for coronavirus while evaluating if the group of employees who had already contracted coronavirus had the same number of reinfections as the group who did not have the virus before.
They found 89 of the 11,052 employees without antibodies contracted coronavirus and had symptoms, while none of the 1,246 employees with the antibodies developed a new infection with symptoms.
Employees with the antibodies were also less likely to contract coronavirus without symptoms and the three who tested positive did not develop coronavirus symptoms.
