In which publication does the CDC initially publish new or updated vaccine recommendations?

The correct answer is the Morbidity and Mortality Weekly Report (MMWR). The CDC utilizes this publication as a primary platform for disseminating new or updated vaccine recommendations. MMWR provides timely and authoritative updates on public health issues, including guidelines for vaccine administration, efficacy, safety, and recommendations based on current epidemiological data. This makes it a crucial resource for healthcare professionals, including pharmacists, who need to stay informed about the latest vaccination policies and practices.

The other options serve different purposes in the field of immunization and public health. "Epidemiology and Prevention of Vaccine-Preventable Diseases" is a resource that compiles comprehensive information on vaccine-preventable diseases and vaccination strategies, but it is not the initial publication for new recommendations. "Needle Tips" is a newsletter associated with immunization which provides practical information and tips for immunization practices but does not serve as the primary source for new recommendations. "Vaccine" is a peer-reviewed journal that presents scientific research and findings related to vaccines but also does not serve as the CDC's initial platform for announcing recommendations.
