Japan's Maternal Vaccine Uptake Stalls at 11.6%

Maternal vaccination against respiratory syncytial virus (RSV) has seen low uptake in Japan, with coverage at just 11.6 percent since its introduction in May 2024. A nationwide survey revealed that high out-of-pocket payments, ranging from 30,000 to 40,000 yen, are a primary barrier for many new mothers. This contrasts sharply with vaccination rates of 30 to 50 percent observed in countries like the United States and Britain.

The survey, conducted by the National Center for Child Health and Development among women who gave birth between July 2024 and August 2025, identified significant awareness issues. Nearly 29 percent of unvaccinated respondents were unaware of the vaccine's benefits, and over 27 percent did not know about the vaccine itself. A strong willingness to vaccinate was expressed, with 77.5 percent stating they would have done so if it were free.
