This past Thursday, the FDA’s advisory committee on vaccines and similar biological products met to discuss COVID-19 boosters for this fall. They voted in favor of updating the vaccines based on Omicron XBB, a variant lineage that has dominated both in the U.S. and globally this year.
Sources and updates for the week of January 29 include wastewater surveillance in New York State, bivalent boosters vs. XBB.1.5, the potential end of the global health emergency, and more.
On Thursday, the FDA’s Vaccines and Related Biological Products Advisory Committee (or VRBPAC) met to discuss the future of COVID-19 vaccines. While the committee readily agreed that our current, Omicron-specific shots are working well and should be used more broadly, it had a hard time answering other questions about future vaccine regimens—largely due to a lack of good data.
Sources and updates for the week of January 22 include respiratory virus hospitalizations, new excess death estimates, wastewater testing on airplanes, and more.
