SARS-CoV-2 Variants: Impact on Vaccines and Serology

This webinar* reviews both the Delta and Omicron variants, including protection associated with vaccination and the important role of the humoral (antibody) and T-cell immune response. Data on declining immunity and breakthrough infection are discussed, including the value of vaccine boosting to improve protection.

Learning objectives:

  • Understand the differing contributions of antibody vs. T-cells in COVID-related immunity
  • Understand the diversity in SARS-CoV-2 viral mutations and the impact on infectivity and immunity
  • Describe similarities and differences in Delta vs. Omicron
  • Describe the benefits of protection associated with vaccination and boosting relative to disease severity
