In the first study of its kind, a team led by researchers from King's College London examined the levels of antibodies in more than 90 confirmed virus patients and how they changed over time. Blood tests showed even individuals with only mild Covid-19 symptoms mounted some immune response to the virus. Of the study group, 60% showed a "potent" viral response in the first few weeks after infection. As long as someone has enough antibodies, they will be able to snub out new infections, giving them immunity. But Monday's research suggests immunity cannot be taken for granted and may not last more than a few months, as is true with other viruses such as influenza.
