The relationship between antibodies for the novel coronavirus (SARS-CoV-2) and immunity, vaccine efficacy, and spread of COVID-19 has received significant attention. Dr. Seheult is back to illustrate why T cells have received less attention than antibodies, but may be more important to long term immunity from COVID-19. Dr. Seheult also discusses how previous infections with common coronaviruses may provide some immunity to SARS-CoV-2, and the hypothesis that reducing the inoculum (initial dose) of SARS-CoV-2 might result in less symptom severity (This video was recorded August 10, 2020).
