The news: Federal health officials are overhauling the recommended US childhood vaccine schedule, dropping from 17 to 11 immunizations, following an order by President Trump in December.

The CDC reclassified childhood immunizations as:

• Recommended for all children: measles, mumps, rubella, polio, pertussis, diphtheria, tetanus, pneumococcal disease, varicella (chickenpox), and one HPV shot (versus two previously).
• Recommended for high-risk children: RSV, hepatitis A and B, dengue, and meningococcal ACWY and B.
• Based on shared decision-making with a doctor: flu, rotavirus, COVID-19, and hepatitis A and B vaccines.

The CDC decision follows months of vaccine oversight changes at federal health agencies led by HHS Secretary Robert F. Kennedy Jr. Those include firing all the CDC’s Advisory Committee on Immunization Practice members and installing 11 handpicked members; cancelling $500 million in mRNA vaccine research grants; and removing the COVID-19 vaccine recommendation for pregnant women and healthy children. The American Academy of Pediatrics (AAP) said it will continue to recommend the previous full schedule of vaccines and called the CDC changes “dangerous and unnecessary.”

Why it matters: While the CDC recommendations are not mandates, state health agencies, healthcare professionals, and parents rely on the guidance for school admission rules and routine pediatric care.

• About half of parents are in line with CDC guidance: 52% thought the childhood vaccine schedule recommended about the right amount, per a KFF and Washington Post report published in October. But 26% thought there were too many vaccines, while 16% said they weren’t sure.
• The same study showed a split between political parties, with 41% of Republicans and 49% of MAGA Republicans who think the CDC recommends too many vaccines for children, compared with 9% of Democrats and 26% of independent parents.

Implications for parents and vaccine makers: For parents and guardians, especially those who are undecided or hesitant about vaccines, the reclassification may increase confusion over which vaccines are essential and raise the risk of delayed or skipped immunizations. Lower uptake risks more infectious disease outbreaks, which is a growing concern as the US sees its highest measles case count in three decades and risks losing its measles-free status.

For vaccine makers, weaker federal guidance could soften demand for shared-decision vaccines like flu and RSV and cool investment in new or next-generation products. Pharma companies also face a communications challenge—speaking up about risks appears self-serving, but staying silent may signal acceptance of the new framework. Partnering with trusted medical groups like AAP, along with local agencies and individual influential healthcare providers, offers a credible way to reinforce the importance of vaccines and influence parents’ decisions.
