A person’s immune response to variants of SARS-CoV-2, the virus that causes COVID-19, depends on their previous exposure—and differences in the focus of immune responses will help scientists understand how to optimize vaccines in the future to provide broad protection.
Vulnerability to different COVID-19 mutations depends on previous infections and vaccination, study suggests
