Immunity to one coronavirus confers cross-immunity to other strains
the verdict
SUPPORTED
the evidence backs this
confidence 78/100
Current immunological research demonstrates that immunity to one coronavirus can confer cross-reactive cellular and humoral responses to other strains, serving as the biological basis for pan-coronavirus vaccine development.
