A newly appointed federal vaccine advisory committee, led by Martin Kulldorff, is reviewing the childhood vaccination schedule and decades-old vaccines. Concerns have arisen due to the committee's skepticism towards vaccines, including the chair's past criticism of pandemic measures. The committee will examine the cumulative effects of childhood vaccines and re-evaluate those not reviewed in over seven years, sparking debate about vaccine safety and recommendations. Discussions include the timing of vaccines, the MMRV vaccine, and the continued use of thimerosal in some flu vaccines. The committee's recommendations could significantly impact vaccination policies and insurance coverage.
