Arms Assigned Interventions
Experimental: Vaccination township
Shinwu township was randomly designated as intervention township which freely vaccinated on grade 1-4 and 5-9 students.
Biological: Trivalent inactivated influenza vaccine
one dose
Other Name: Brand Name: VAXIGRIP
No Intervention: Control townships
Guanyin township was designated as control township which only provide free vaccination on grade 1-4 students.

Detailed Description:
School children were found to be the possible spreaders of the influenza. The successful prevention measure on school children was crucial for controlling the epidemic. In Taiwan, the national influenza immunization program on the grade 1-2 students started in winter, 2007. In this intervention study, the two study townships with 27 schools were included as our study population. The three time questionnaires were issued for collecting the health status of the children during the influenza season. The information on the vaccines' safety was also collected after the vaccination. The community collaborative clinics were responsible for taking the specimens.
