According to a new study, bugs are less likely to be re-infected with coronavirus at least six months after contracting.
The research, which involved more than 12,000 front-line health care workers in Britain, found that only three of the 1,246 participants who had already developed COVID-19 antibodies responded positively to the virus – and were all asymptomatic.
Of the 11,052 medical workers without antibodies, 89 were infected with symptoms and 79 developed asymptomatic infections.
The study, which has not yet been peer-reviewed, covers a 30-week period between April and November 2020. It was uploaded to the printprint server Medrexive on Thursday.
“This is really good news because we can be confident that, very soon, most people who get COVID-19 will not get it again,” said David Eyre, a professor in the Nuffield Department of Population Health at Oxford. Co-led the study.
“Most people infected with COVID-19 are protected against refraction for at least six months.”
Ayre said a team of scientists would monitor the health care workers.
“We will carefully follow this set of staff to see how long-term safety lasts and whether previous infections affect the severity of the infection if people are re-infected,” he said.
UK research is another study of the immune system in recent days.
On Tuesday, scientists at the La Jolla Institute of Immunology in California discovered that most of their native patients still have a second round of coronavirus-fighting immunity – indicating that immunity can last for years.
According to Johns Hopkins University data, the epidemic has so far infected more than 57 million people worldwide, including more than 110 million people in the United States.
