Virologist Dr. Andrew Pekosz returns to the podcast to talk with Dr. Josh Sharfstein about BA.2, a "not unexpected but tiring" new sibling of the omicron variant. They discuss who should be most concerned about getting sick and what might happen in the coming weeks. They also discuss reports of "deltacron," a viral recombination of delta and omicron, and what we can learn from Hong Kong and China's COVID crises about the omicron variant.
