The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides advice to the Centers for Disease Control and Prevention, normally meets 3 times per year to develop US vaccine recommendations. The ACIP met February 28 to 29, 2024, to discuss coronavirus disease (COVID-19) vaccines, chikungunya vaccines, DT vaccine, influenza vaccines, polio vaccines, RSV vaccines, meningococcal vaccines, pneumococcal vaccines and Vaxelis (DTaP, Inactivated Poliovirus, Haemophilus influenzae b Conjugate & Hepatitis B Vaccine). This update summarizes the proceedings of these meetings, with an emphasis on topics that are most relevant to the pediatric population. Major updates for pediatric clinicians include information about changes on influenza vaccine composition, meningococcal vaccination considerations, updated guidance for children with a contraindication to pertussis-containing vaccines, and recommendations of the world’s first chikungunya vaccine for certain populations.
