How Did Vaccine Policies Actually Change In 2025?

Since 1955, when Congress passed the Polio Vaccination Assistance Act, the federal government has been in the business of expanding access to vaccines. That is, until this year.

2025 has been filled with almost daily news stories about federal agencies, under the direction of Health Secretary Robert F. Kennedy Jr., casting doubts about vaccine safety, including unsubstantiated claims about links to autism. These agencies have also been taking steps that could roll back access to vaccines, including for hepatitis B and COVID-19.

But we’ve found it very hard to sort out what these talking points and recommendations mean in practice. KFF Health News journalists Jackie Fortiér and Arthur Allen join Host Flora Lichtman to discuss, one year in, what this administration’s stance on vaccines has meant practically—for vaccine access, and vaccine uptake.
