The Centers for Disease Control and Prevention (CDC) has updated its guidance on COVID-19 vaccination, moving to an “individual-based decision-making” model. Under this approach, the CDC recommends that individuals consult with a healthcare professional to discuss the risks and benefits of receiving a COVID-19 vaccine before making a decision.

In addition to changes in COVID-19 vaccine recommendations, the CDC now advises that toddlers receive chickenpox (varicella) immunization separately from the measles, mumps, and rubella (MMR) vaccine. This change follows evidence presented by the CDC Immunization Safety Office to the Advisory Committee on Immunization Practices. The data showed that healthy toddlers aged 12 to 23 months may face an increased risk of febrile seizure seven to ten days after receiving a combined MMR-varicella vaccine compared to those who get the chickenpox shot separately.

The Trump Administration’s shift in national immunization policy is discussed further in the November/December 2025 issue of Innovations.
