KEYWORDS: Influenza, BRFSS
BACKGROUND: In 2000, delays were expected in influenza vaccine distribution due to manufacturing issues. In October 2000, the Advisory Committee on Immunization Practices (ACIP) issued updated recommendations to target initial vaccination efforts to persons at highest risk of complications from influenza, and postpone mass vaccination campaigns. Subsequently, 27 million doses were distributed by end of October (76 million in 1999), 48 million by end of November (77 million in 1999), 70 million by end of December, and 7 million doses were not distributed.
OBJECTIVE(S): To assess how vaccine supply delays affected influenza vaccine utilization during 2000-01, and compliance with the updated ACIP recommendations.
