The U.S. Centers for Disease Control and Prevention (CDC) has updated the childhood immunization schedule, following a review ordered by former President Donald Trump comparing U.S. vaccination practices with those of other developed nations. The change, announced on January 5, has raised questions for parents, doctors, and insurers about which vaccines children should receive.
The revision does not reflect new scientific evidence on vaccine safety or effectiveness, experts say. Dr. Daniele Gusland, assistant professor of pediatrics at UCSF Benioff Children’s Hospital, noted that previous changes to the CDC’s immunization schedule typically involve public discussions and input from experts through the Advisory Committee on Immunization Practices. “None of that happened this time,” she said.
The updated guidelines move six vaccines—COVID-19, seasonal flu, hepatitis A, hepatitis B, respiratory syncytial virus (RSV), and rotavirus—from universal recommendations to a shared clinical decision-making model. Under this approach, parents and doctors discuss the benefits and risks of the vaccine for each child before deciding whether to proceed. The CDC says this method ensures children at higher risk still receive protection while giving families greater choice.
Vaccine experts caution that shared decision-making does not mean vaccines are optional. Pediatricians overwhelmingly recommend these immunizations based on decades of evidence demonstrating their role in preventing serious illnesses. Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, highlighted the risks of not vaccinating, pointing to countries like Denmark, which do not recommend the rotavirus vaccine for all children. “Every year, about 1,300 young children there are hospitalized with fever, vomiting, and diarrhea from rotavirus,” Offit said. In the U.S., universal vaccination has nearly eliminated such hospitalizations.
The shift has also caused confusion among the public. A University of Pennsylvania survey found that more than 40 percent of respondents misunderstood shared clinical decision-making to mean parents can decide independently, while over 10 percent were unsure what it meant at all. Experts note that meaningful discussions between doctors and parents require time, knowledge, and privacy—resources that are often limited in busy clinics or pharmacies.
Despite the change, coverage for vaccines remains intact. Dr. Mehmet Oz, commissioner of the Centers for Medicare and Medicaid Services, said all previously recommended vaccines will continue to be covered by federal and private insurance without cost-sharing. In some states, regulations allow pharmacists to administer vaccines that the CDC now designates for shared decision-making, helping maintain access.
The CDC emphasizes that the adjustments do not remove any vaccines from the schedule. Instead, the agency aims to balance evidence-based protection with personalized guidance, reflecting the government’s focus on both public health and parental involvement in decisions about immunization.
