Future Measures Following the Discontinuation of Production and Sales of the DPT-IPV and Hib Vaccines

The production and sale of the quadrivalent vaccine have been discontinued

Due to the introduction of the pentavalent vaccine as a routine vaccination starting April 1, 2024, the production and sale of the quadrivalent vaccine have been discontinued.

In routine vaccinations, the same type of vaccine is generally administered the required number of times; however, if there are unavoidable circumstances recognized that prevent following this standard method, it is possible to switch to vaccination with either the "trivalent vaccine (diphtheria, pertussis, tetanus) + inactivated polio vaccine" or the "pentavalent vaccine" after consulting and deciding with a medical institution. (Please check the examples of vaccination below.)

　Regardless of the number of Hib vaccine doses already administered, it is acceptable to receive the pentavalent vaccine.

Please consult with the medical institution, as vaccine stock availability may vary depending on the facility.

 

[Example of Vaccination]

• If three doses of the four-component combined vaccine and Hib vaccine have been administered ⇒ one additional dose of the pentavalent vaccine
• If three doses of the four-component combined vaccine and four doses of the Hib vaccine have been administered ⇒ check the vaccine availability and consult with a medical institution to receive vaccination by one of the following methods

1. Administer one additional dose each of the combined triple vaccine and the inactivated polio vaccine
2. One additional dose of the pentavalent vaccine

The production and sale of the Hib vaccine (ActHIB) will be discontinued

The Hib vaccine "ActHIB (Sanofi)" will be discontinued with the product expiring on October 16, 2026.

Note: From now on, the only vaccine for Hib infection will be the pentavalent vaccine.

Therefore, if vaccination against Hib infection cannot be completed using the Hib vaccine, the missing Hib component vaccination can be completed using the pentavalent vaccine. (Please check the example of vaccination below.)

 

[Example of Vaccination]

If you have received the Hib vaccine 3 times and the DTaP vaccine 4 times ⇒ as the 4th dose of the Hib vaccine, receive the DTaP-IPV vaccine once

Regarding the Pre-vaccination Screening Form When Switching Vaccines

When switching vaccines to administer the vaccination, a medical questionnaire for the vaccine to be administered is required.

If you do not have the medical questionnaire for the vaccine to be administered, please contact the medical institution conducting the vaccination or the Health Center (042-378-3421).
