Support for immunization-related child tax credit programs: A survey of parents in the United States.

Objectives: Describe parental attitudes toward proposed tax credit policies that would promote pediatric immunization coverage in the United States. Methods: A national survey was conducted from August-September 2025. Participants were recruited from an online panel and asked to use Likert scales to characterize support for proposed policies that would: revise the eligibility criteria of the existing federal child tax credit to include age-appropriate immunization, create a new tax credit for parents providing evidence that their children are age-appropriately immunized, or create a new tax credit for families residing in a state where at least 95% of the children are age-appropriately immunized. Results: The data analysis included 1006 participants. 53.9% expressed support for revising the eligibility criteria of existing child tax credits to include age-appropriate immunization. 62.6% expressed support for creating a new tax credit for parents providing evidence that their children are age-appropriate immunized. 57.4% expressed support for creating a new tax credit for families residing in a state where at least 95% of the children are age-appropriately immunized. Support differed according to participant characteristics, but notably, not according to partisanship or welfare program participation. Conclusions: Most parents in this survey supported novel tax policies that may improve immunization coverage.
