Nationwide, COVID-19 spread appears to be in a plateau: not substantially increasing, but not substantially decreasing, either. Officially-reported cases dropped by only 1% this week compared to the week prior, while wastewater data shows that the coronavirus concentration in our sewage hasn’t changed significantly for the last month.

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.

But we know enough to say that this variant is bad news for an already overstretched healthcare system.

China has rolled back some of its most rigorous COVID-19 safety policies, essentially moving away from its “zero COVID” strategy, following recent protests. I am no expert on China’s political or health policies here, but I did want to share some reflections on what this rollback could mean for global COVID-19 data.

Last month, the CDC started publishing data from a surveillance program focused on international travelers coming into the U.S. I talked to bioinformatics experts involved with the program to learn more about how it works.
