Survey of pediatricians concerning the human papillomavirus vaccine in Japan: Positive attitudes toward vaccination during the period of proactive recommendation being withheld.

In 2013, the human papillomavirus (HPV) vaccine was introduced as a national immunization program in Japan. However, because of a wide range of symptoms after vaccination, the Japanese Ministry of Health, Labor and Welfare decided to withhold proactive recommendations, a situation that has continued for more than eight years. During the withholding, absent any scientific or epidemiological evidence to support a relationship between HPV vaccines and symptoms, we surveyed pediatricians at Osaka Pediatric Association and analyzed the changing of attitudes in 2020 (n = 200) and 2021 (n = 190). A total of 44.5% respondents in 2020 and 67.9% in 2021 offered HPV vaccination to targets at the time the questionnaire was administered, indicating that the rate of pediatricians providing vaccines had increased significantly (p < .001). A total of 74.0% of respondents in 2020 and 77.9% in 2021 had a positive opinion of HPV vaccination (p = .369), and 64.3% in 2020 and 78.3% in 2021 were "not at all concerned or had almost no concern" about HPV vaccination (p = .002). These results suggest that, in general, most physicians who are primarily responsible for HPV vaccination in a given field had a positive attitude toward vaccination during the proactive recommendation having been withheld.
