Advisory Committee on Immunization Practices (ACIP)

ACIP approved the following recommendations by majority vote at its June 2018 meeting:

• Reaffirmed the seasonal influenza recommendations for the 2018-2019 influenza season
• Anthrax vaccine use for post-exposure prophylaxis in a mass vaccination campaign, including:
  • The intramuscular route of administration may be used if the subcutaneous route of administration presents clinical, operational, or logistical challenges that may delay or prevent effective vaccination
  • Should there be an inadequate supply of anthrax vaccine available for post-exposure prophylaxis, either 2 full doses or 3 half doses of anthrax vaccine absorbed (AVA) may be used to expand vaccine coverage
  • In immunocompetent adults aged 18 through 65 years, antimicrobials given in conjunction with vaccine may be discontinued at 42 days after the first vaccine dose or 2 weeks after the last vaccine dose, whichever comes later

These recommendations have been adopted by the CDC Director and will become official once published in MMWR.
