Fig. 1. — Considering the target ages of the PNI (9 to 14 years old), the first dose of HPV vaccine was given to 4,304 children in 2018 and to 2,974 children in 2017 (Ratio 2018-2017 = 1.45). The difference was due to the higher vaccination rate in the age range between 9 and 10 years old (*Ratio 2018-2017 = 3.1).
