Update From the Advisory Committee on Immunization Practices.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts, meets 3 times per year to develop recommendations for vaccine use in the United States. The group has 15 voting members, and each member's term is 4 years. ACIP members and Centers for Disease Control and Prevention staff discuss the epidemiology of vaccine-preventable diseases and vaccine research, effectiveness, safety data, and clinical trial results. Representatives from the American Academy of Pediatrics (J. D. C. and D. W. K.) and the Pediatric Infectious Diseases Society (S. T. O.) are present as liaisons to the ACIP. The ACIP met on June 20 and 21, 2018, to discuss influenza vaccine effectiveness and safety, anthrax vaccination in the setting of a mass exposure, human papillomavirus vaccine, mumps vaccine, Japanese encephalitis vaccine, and pneumococcal vaccination among adults.
