Subsidy Programs for Seasonal Influenza Vaccination of Children and Pregnant Women in Japanese Municipalities.

ABSTRACT

In Japan, influenza vaccination is offered to children and pregnant women at clinics or hospitals as an elective, self-funded treatment, as the vaccination is not included in the national vaccination subsidy program. However, some Japanese municipalities offer a discretionary subsidy for seasonal influenza vaccination of children and pregnant women as a local policy. We identified these local subsidy programs during 2019/2020 seasonal influenza season by conducting a cross-sectional survey across Japan. Out of a total of 1741 municipalities, responses were received from 1732; therefore, the response rate was 99.5%. The local influenza vaccine subsidy programs for children were offered in 45.7%, and for pregnant women in 10.2%, of Japanese municipalities. This is the first survey of subsidy programs for pregnant women. While policy diffusion of subsidy programs for children was observed during the 9 years since a previous study, such programs for pregnant women remain limited. Despite many municipalities having subsidy programs, we found that their provision still remains limited when viewed as a whole.
