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, each of whom is appointed to a 4-year term. 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. The ACIP met on October 25 and 26, 2017, to discuss herpes zoster vaccine, the child/adolescent and adult vaccination schedules, Japanese encephalitis (JE) epidemiology and vaccines, pneumococcal vaccines, anthrax vaccines and disaster preparedness, hepatitis A outbreaks, influenza surveillance and vaccination coverage, vaccine safety, and considerations for a potential third dose of measles-mumps-rubella (MMR) vaccine to combat ongoing mumps outbreaks. Representatives from the American Academy of Pediatrics (AAP) (Y. A. M. and D. W. K.) and the Pediatric Infectious Diseases Society (S. T. O.) were present as liaisons from their respective organizations to the ACIP.
