The FDA's vaccine advisors voted 8 to 0, with one abstention, in favor of a monovalent XFG vaccine for COVID-19 shots for the 2026-2027 season.

The families of two Black infants who were unknowingly enrolled as test subjects in a mid-1960s vaccine trial for a respiratory virus and died shortly afterward have sued the United States government. Ross Otto Hambrick and Victor Marcellus King were just a few months old when they were administered a vaccine for respiratory syncytial virus, or R.S.V., at a children’s clinic in Washington, D.C., between 1965 and 1966 without their families’ knowledge or consent, according to a lawsuit filed on May 22. Both died from the disease, coupled with bacterial pneumonia, about a year later, when Ross Otto was 14 months old and Victor 16 months. (Tumin, 5/28)

Early results from a controversial pilot program testing the use of artificial intelligence to automate some prescriptions refills are in and being viewed as a promising test case for how AI may next be used in healthcare. In January, the state of Utah launched the pilot with artificial intelligence platform Doctronic. The state allowed the company to use its AI chatbot to manage prescription renewals for 192 drugs used to treat chronic conditions such as diabetes, depression and high blood pressure. The 12-month pilot is being widely watched within the industry, and there have been questions raised about its safety, legality and the broader use of AI in healthcare. (Famakinwa, 5/28)
