Last week, I asked you, COVID-19 Data Dispatch readers, to send me your stories of challenges you experienced when trying to get this fall’s COVID-19 vaccines. I received 35 responses from readers across the country, demonstrating issues with insurance coverage, pharmacy logistics, and more.
We now have two new COVID-19 vaccines available for this year’s respiratory virus season, one from Pfizer and one from Moderna, which are expected to perform well against current variants. The FDA approved both vaccines this week, and the CDC recommended them for almost all Americans. A third option, from Novavax, may become available in the coming weeks as well.
Since BA.2.86 emerged a couple of weeks ago, scientists around the world have been racing to evaluate this variant. Several teams posted data in the last week, and the news is promising: while BA.2.86 does have an advantage over past variants, the lab findings suggest that vaccines (including the upcoming boosters) and past infections provide protection against it.
I received a couple of reader questions in recent weeks that I’d like to answer here, in the hopes that my responses will be more broadly helpful. The questions cover COVID-19’s incubation period (i.e. time between exposure and symptoms), vaccine effectiveness for this fall, and nasal sprays.
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.
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 December 4 include new CDC grants to support public health infrastructure, breakthrough COVID-19 deaths, monoclonal antibodies, and more.
