Virology Lectures 2020 #14: Adaptive immunity

The final barrier to virus reproduction in the host is the adaptive immune system, which is tailored to the pathogen and has memory. In this lecture we examine how B and T cells are instructed by the innate immune system, how antibodies and cytotoxic T cells are made, and their roles in preventing and resolving virus infections. Includes explanations of rapid tests for SARS-CoV-2 antibodies and antibody therapy for COVID-19 patients.
