The XBB 1.5 variant of COVID is quickly becoming the dominant strain in the US, and we’re seeing more cases here in Canada too. The WHO has called it the most transmissible variant of the virus we’ve seen so far.

Some people are calling it ‘The Kraken.’ But not Dr. Angela Rasmussen. She’s a virologist at VIDO, the Vaccine and Infectious Disease Organization at the University of Saskatchewan, and she’ll walk us through what we know about this variant, what we don’t know, and how concerned we should be.
