Notes

For routine vaccinations, the same type of vaccine is generally administered the required number of times. However, if the vaccine stock runs out and the number of doses for the DPT-IPV vaccine and Hib vaccine are matched, it is possible to switch to the pentavalent vaccine for vaccination.

At that time, it will be necessary to replace the preliminary examination form for the DPT-IPV vaccine and Hib vaccine with the preliminary examination form for the DPT-IPV-Hib vaccine. Please bring your Maternal and Child Health Handbook to the Health Center. After confirming your vaccination history, we will provide you with the preliminary examination form and other documents.

 

If the number of doses for the DPT-IPV vaccine and Hib vaccine do not match, and it is not possible to switch to the DPT-IPV-HepB vaccine for vaccination, please contact the medical institution where the vaccination is administered or the Health Center (042-378-3421).
