The results to questions in our three surveys about the responders’ opinion on the HPV vaccine. The rate of doctors who answered ‘yes’ to the question; (a) Whether the Japanese government should restart its HPV vaccine recommendation (b) Whether to recommend HPV vaccines for teenagers in their daily practice (c) Whether their own daughters had been inoculated after the suspension of recommendation. The bar with diagonal lines is the result of the first wave of survey in 2014, bar with dots is from the second wave of survey in 2017, and the black bar is from the third wave of survey. A p-value was calculated from the chi-squared test or Fisher’s exact test.
