In this ninth episode, we'll tackle the different conundrums we face with the emergence of new and highly transmissible SARS-COV-2 variants. Get ready to delve into some thought provoking scientific concepts when it comes to how this virus appears to be evolving and where we stand with our current and future vaccination goals. The episode parses out the most worrisome mutations, how they were able to evolve and why they are such a concern. Experts talk about recent data from Johnson & Johnson and Novavax, which are tell tale signs of the issues we have ahead. They also discuss where our currently authorized vaccines - Pfizer, Moderna, AstraZeneca -- stand to combat the new variants. We'll explore what manufactures are doing to keep up with new mutations and the various challenges in chasing a moving target. While experts agree that this will probably not be a once in a lifetime vaccination, they make comparisons to seasonal influenza and remain debated on how often we might need to revaccinate. Finally, experts discuss the best approach forward with both the vaccines and prudent social behaviors to ensure that we don't lose this pandemic battle due to complacency.
