NPO Himawari no Kai (President: Seiko Noda / Location: Chiyoda-ku, Tokyo) has announced its policy to further strengthen efforts toward proper information provision and promotion of the RSV vaccination (maternal immunization), which became a routine vaccination starting April 1, 2026.
Moving forward, the organization will partner with the Japan Midwives Association to strengthen information provision to pregnant women through midwives, initiating grassroots promotional activities. This vaccination is conducted at public expense (*), providing a vital preventive opportunity for pregnant women without out-of-pocket costs.
Furthermore, new insights regarding the characteristics of information that influence vaccination behavior were obtained from a survey (n=531) on pregnant women's vaccination intentions.
* Pregnant women between 28 weeks 0 days and 36 weeks 6 days of pregnancy at the time of vaccination are eligible for routine vaccination (= public funding).
## ■ Background: Risk of Severity in Infants and the Importance of Maternal Immunization
RSV infection easily becomes severe in infants, often requiring hospitalization.
The risk of severe illness is particularly high in newborns, making prevention through 'maternal immunization'—where antibodies are transferred from the mother through the placenta—crucial.
As of April 1, 2026, this vaccination has been positioned as a routine vaccination (Category A disease) and is being rolled out nationwide as a public preventive measure for pregnant women.
## ■ Past Initiatives: Distribution of Educational Materials Nationwide
Prior to the routine vaccination status, Himawari no Kai produced and distributed the following educational materials:
- Educational posters
- Explanation handbooks for local government officials, midwives, and nurses
These materials have been deployed to local governments and obstetrics and gynecology clinics nationwide.
