A new U.K. study of more than 3,000 health care workers says that coronavirus antibodies decline by half in just under three months and disappear after about four and a half.
The findings suggest people may not be able to depend on antibodies as a form of protection from a second infection, as several studies still aren’t clear about what level of immunity they provide and for how long.
What’s more, antibodies last longer in people who had symptoms and fade quicker in those who never did.
The non-peer reviewed study was published Wednesday in the pre-print server medRxiv.
