In response to delays in production and distribution of influenza vaccine
during 2000, the Advisory Committee on Immunization Practices (ACIP) recommended
that first-available supplies of vaccine be administered to persons at increased
risk for complications from influenza and to health-care workers. The committee
also recommended that mass vaccination campaigns for the 2000-01 season be
delayed until the availability of supply was assured.1,2 ACIP
issued similar recommendations for the 2001-02 influenza season3 and
has incorporated this prioritization into its annual influenza recommendations.4
To assist vaccinators in determining if administration of influenza
vaccine should be prioritized because of anticipated delays or shortages,
ACIP requested that CDC develop a process to assess the projected vaccine
supply in advance of the influenza vaccination season. Each year, this process
will be conducted collaboratively by CDC, the Food and Drug Administration,
and the manufacturers who produce influenza vaccine.
On August 11, 2003, CDC determined that vaccine production for the 2003-04
influenza season is proceeding satisfactorily and that projected production
and distribution schedules will allow for sufficient supply of influenza vaccine
during October and November. Therefore, influenza vaccination can proceed
for all high-risk and healthy persons, individually and through mass campaigns,
as soon as vaccine is available.
