Primate study reveals relationship between neutralizing antibodies and T cell responses

A rhesus macaque study argues that CD8⁺ T cells contribute to immunity against COVID-19, while simultaneously suggesting that antiviral antibodies alone, if at a high enough titer, can protect against SARS-CoV-2.

Predictions about correlates of protection for COVID-19 have primarily focused on neutralizing antibody levels, as much less is known about whether and to what degree CD8⁺ T cells contribute to immunity...
