The FDA’s Vaccines and Related Biological Products Advisory Committee rejected an sBLA for a third, booster dose of the COVID-19 vaccine Comirnaty from Pfizer Inc.-Biontech SE for ages 16 and over, then unanimously approved a recommendation for those ages 65 and older along with individuals at high risk of severe COVID-19 to get the booster.

In late August, data from a phase IIb dose-finding study showed izencitinib, a gut-selective pan-JAK inhibitor for treating ulcerative colitis, failed to meet its primary endpoint.
