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. There usually are 15 voting members, but at the June 2019 meeting, only 14 were present; each member's term is 4 years. ACIP members and Centers for Disease Control and Prevention (CDC) 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 (AAP) (Y. A. M. 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 26 to 27, 2019, to discuss the use of human papillomavirus (HPV) vaccine in adults, pneumococcal vaccines in adults, measles updates, zoster vaccine, influenza vaccines, hepatitis A virus (HAV) vaccines, meningococcal vaccines, and dengue vaccine.
