Others detect antibodies to a different part of the virus called the nucleocapsid protein, which are produced in response to infection, but not by the current vaccines. In addition to the antibodies that are generated after vaccination, people also generate T cell immunity, which may be equally important, but harder to measure and not reflected in an antibody test.. While a positive antibody test result can be used to help identify people who may have had a prior SARS-CoV-2 infection, more research is needed in people who have received a COVID-19 vaccination.
