With the country experiencing a relatively large summer wave of COVID-19, the Food and Drug Administration is considering signing off on this year's strain-matched COVID-19 vaccines as soon as this week, according to a report by CNN that cited unnamed officials familiar with the matter.

Last year, the FDA gave the green light for the 2023–2024 COVID shots on September 11, close to the peak of SARS-CoV-2 transmission in that year's summer wave. This year, the summer wave began earlier and, by some metrics, is peaking at much higher levels than in previous years.

Currently, wastewater detection of SARS-CoV-2 shows "very high" virus levels in 32 states and the District of Columbia. An additional 11 states are listed as having "high" levels. Looking at trends, the southern and western regions of the country are currently reporting SARS-CoV-2 levels in wastewater that rival the 2022–2023 and 2023–2024 winter waves, which both peaked at the very end of December.

A small study in Texas suggests that human bird flu cases are being missed on dairy farms where the H5N1 virus has taken off in cows, sparking an unprecedented nationwide outbreak.

The finding adds some data to what many experts have suspected amid the outbreak. But the authors of the study, led by researchers at the University of Texas Medical Branch in Galveston, went further, stating bluntly why the US is failing to fully surveil, let alone contain, a virus with pandemic potential.

"Due to fears that research might damage dairy businesses, studies like this one have been few," the authors write in the topline summary of their study, which was posted online as a pre-print and had not been peer-reviewed.

A sixth student at Florida's Manatee Bay Elementary School outside of Fort Lauderdale has a confirmed case of measles, health officials announced late Tuesday. However, health officials are not telling unvaccinated students who were potentially exposed to quarantine.

The school has a low vaccination rate, suggesting that the extremely contagious virus could spark a yet larger outbreak. But in a letter sent to parents late Tuesday, Florida Surgeon General Joseph Ladapo—known for spreading anti-vaccine rhetoric and vaccine misinformation—indicated that unvaccinated students can skip the normally recommended quarantine period.

The letter, signed by Ladapo, noted that people with measles can be contagious from four days before the rash develops through four days after the rash appears. And while symptoms often develop between 8 to 14 days after exposure, the disease can take 21 days to appear. As such, the normal quarantine period for exposed and unvaccinated people, who are highly susceptible to measles, is 21 days.
