Antibodies from original strain COVID-19 infection don't bind to variants

Antibodies from original strain COVID-19 infection don't bind to variants: People infected with the original strain of the virus that causes COVID-19 early in the pandemic produced a consistent antibody response, making two main groups of antibodies to bind to the spike protein on the virus's outer surface. However, those antibodies don't bind well to newer variants, a new study from the University of Illinois Urbana-Champaign found.
