Everyone’s antibody response is different. That’s why our test is too.
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus.
After vaccination or infection, immune response is individual and variable. Variation in responses have been linked to age, sex, ethnicity in addition to previous SARS-CoV-2 infection status. Importantly, the clinically vulnerable are reported to generate lower levels of antibodies compared with healthier people following vaccination or infection.
