Prevention and control of influenza: Part I, Vaccines. Recommendations of the Advisory Committee on Immunization Practices (ACIP).

These recommendations update information on the vaccine available for controlling influenza during the 1993-94 influenza season (superseding MMWR 1992;41(No. RR-9):1-17.) The principal changes include information about a) the influenza strains in the trivalent vaccine for 1993-94, b) the effectiveness of influenza vaccine, and c) side effects and adverse reactions. Antiviral agents also have an important role in the control of influenza. Recommendations for the use of antiviral agents will be published later in 1993 as Part II of these recommendations.
