At this week’s two-day meeting of advisers to the Centers for Disease Control and Prevention, the discussion centered around how fast-growing and complicated the agency’s vaccine schedule has become.

The Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) met on Oct. 25 and 26, for their annual review of the childhood and adult schedules, as well as updates on changes to come.

Much of the discussion revolved around how complicated the schedule is because it’s growing so quickly.

Chair Grace Lee made the comment, “I can see we’re going to need a bigger refrigerator for all the vaccines.”
