About the Routine Vaccination of RS Virus (Maternal and Child Immunity Vaccine) Vaccination

From April 1, 2026, RS virus (maternal and child immunity vaccine) vaccination has become a routine vaccination.

Along with the introduction of routine vaccination, we have sent notifications and preliminary examination forms for the RS virus vaccination to pregnant women known to the city (such as those who have submitted a pregnancy notification to the city).

If you do not receive vaccination notifications due to moving in or other reasons, please contact the Parent and Child Comprehensive Support Center Section of Inagi City (042-378-3434).

What is RS Virus Infection?

An acute respiratory infection caused by RS virus, which is a common infection among infants and young children.

RS virus can infect repeatedly regardless of age, but the initial infection is said to be more likely to become severe. In particular, if infected within 6 months after birth, it can become severe, causing bronchiolitis or pneumonia. It is said that more than 50% of infants and young children are infected at least once by the age of 1, and almost 100% by the age of 2.

About the Effectiveness of the Vaccine
