The FDA is backing a second omicron booster for high-risk groups. Vaccine advisers to the Centers for Disease Control and Prevention are scheduled to meet Wednesday to discuss the second booster, and CDC Director Rochelle Walensky is expected to sign off quickly. Federal health officials will not formally urge that people get a second booster. Instead, the “permissive” policy says they may get one if they want. #shorts #covid #vaccine #fda #booster
