Evidence since 2023 shows growing public and political questioning of non‑COVID school vaccine requirements in the U.S.
Public opinion data: Pew finds that overall support for requiring the MMR vaccine for public‑school attendance fell from 82% in 2019 to 69% in 2025, with Republican support dropping from 79% to 52%; Pew explicitly links this to post‑COVID debates and notes that school vaccine policies have become a flashpoint as states like Florida move to roll back requirements. (pewresearch.org) Gallup likewise reports that the share of Americans who say it is "extremely important" for parents to vaccinate their children fell from 58% in 2019 to 40% in 2024, and that only a bare majority now say government should require childhood vaccines, down from 62% in 2019. (news.gallup.com) A 2025 KFF poll finds support for school requirements still high overall but "eroding" among Republicans and parents, with more parents delaying or skipping routine childhood shots and about one in six adults—rising to one in four Republicans—saying public schools should not require any vaccines.

Behavior and policy: CDC surveillance shows that kindergarten vaccine exemptions (overwhelmingly non‑medical) reached record highs in 2022–23 and increased again in 2023–24, while coverage for required vaccines like MMR, DTaP, and polio has declined below pre‑pandemic levels in most states, indicating more families are opting out of school requirements. (cdc.gov) Several high‑profile state actions explicitly challenge school mandates for non‑COVID vaccines—for example, Florida’s move to drop or eliminate long‑standing school vaccine requirements (for chickenpox, hepatitis B, etc.) in the name of "parental choice," and a West Virginia ruling allowing religious opt‑outs in a state that previously permitted only medical exemptions.

Together, these trends—declining support for school vaccine mandates, rising non‑medical exemptions, and active political efforts to loosen requirements for traditional childhood vaccines—match Friedberg’s prediction that in the years after COVID, there would be growing public questioning of whether existing school vaccine requirements for other illnesses are appropriate.
