Some 88% of participants who tested positive for a previous infection retained antibodies for six months, according to the report by UK Biobank, a major biomedical database. The first dose of these mRNA vaccines trains the immune system to recognize and attack the spike protein on the surface of SARS-CoV-2, the virus that causes COVID-19. According to the Food and Drug Administration (FDA), monoclonal antibodies are proteins made in a laboratory that mimic your body’s immune response. People who have recovered from COVID-19 had a robust antibody response after the first mRNA vaccine dose, but little immune benefit after the second, research finds.
