    Abstract

    Low vaccination rates with pneumococcal vaccine in elderly persons in Japan are thought to be related to low levels of public subsidy. To identify strategies to increase future pneumococcal vaccination rates, we examined the relationship between public subsidies and vaccination rates. We also investigated the influence of free vaccinations after the 2011 Great East Japan Earthquake on vaccination rates in the three Tohoku prefectures of Japan. We surveyed a total of 1742 municipalities in Japan about whether public subsidies were available and their monetary amount. Vaccination rates with the 23-valent pneumococcal vaccine were calculated as the "cumulative amount shipped to each municipality divided by the population aged ≥65 years." There were no subsidies in 773 municipalities (44.4%). In those municipalities with public subsidies, larger subsidies were significantly associated with elevated vaccination rates (p < 0.0001). Compared to a mean vaccination rate of 25.4% throughout Japan, the vaccination rate was 52.1% in municipalities where the full cost was subsidized. The three prefectures (Iwate, Miyagi, and Fukushima) most affected by the Great East Japan Earthquake ranked as the top three prefectures for vaccination rates in Japan, presumably as a result of the free vaccination campaign for disaster victims. Our findings show that public subsidies play an important role in increasing the vaccination rate. The free vaccinations given to disaster victims after the Great East Japan Earthquake helped to achieve extremely high vaccination rates in the three Tohoku prefectures. We suggest that such public subsidies should be promoted throughout Japan.
