The average attack rate of the class was 30.81.The time distribution was mainly from November to December, and the pathogen type was Agnh _ 3N _ 2. The vaccination rate of the whole school was lower than that of the non-diseased class. The incidence of influenza vaccine was 35.377.The incidence rate of vaccinator was 12.077.The rate of vaccine protection was 65.880.The incidence rate of unvaccinated influenza vaccine was 3.2525, the incidence rate of vaccinator was 0.36and the rate of vaccine protection was 88.92. Conclusion Influenza vaccination in school nursery can effectively prevent agglomeration influenza epidemic.
