SARS-CoV-2 variants have been with us since the dawn of the pandemic, but only recently has their impact on disease and immunity been broadly recognized. Variants of concern such as Delta are particularly troubling as they harbour one or more characteristics such as increased infectiousness or resistance to neutralizing antibodies that can facilitate transmission.

Variants of interest display concerning mutations that require close monitoring. Genetic diversity enables the virus to adapt in ways that can impact immunity from vaccination or recovered infection, as well as some diagnostic testing.

This webinar will discuss potential consequences of SARS-CoV-2 mutations and variants on vaccination status and laboratory testing.

The role of serology will be discussed, including accumulating evidence that levels of antibody correlate to immune protection and are impacted by some variants. The critical role of monitoring for variants with easy-to-use RT-PCR-based molecular testing will be reviewed.

  • Define Variants of Concern vs. Variants of Interest and the impact of mutations
  • Understand the role of antibody testing with variants
  • Viral genetic evolution:
    • What are the potential consequences on SARS-CoV-2 detection?
    • How simple to use RNA-based molecular testing can detect mutations and allow the identification of major variants
