Quick Reference

Who is eligible and when will vaccinations begin?

Eligibility

All persons 12 and over who have completed both their first and second doses of the COVID-19 vaccine and have a resident record in Hiroshima City are eligible to receive one Omicron-adapted vaccine.

If it has been five or more months since you last received a vaccine (the original vaccine, not the one adapted for the Omicron variant), you can receive the Omicron-adapted vaccine.

Note: the period between vaccinations may be shortened depending on the policy of the Japanese national government.

Vaccines available

No matter which kind of vaccine you received previously, Omicron-adapted vaccines from Pfizer and Moderna will be available to you. Both vaccines are bivalent vaccines that are effective against the Omicron variant (BA.1) and the original COVID-19 viral strain. For those who have not yet received their COVID-19 vaccine, you will be given the original vaccine for your first and second doses.

Note: there are differences in the ages of those who can receive the vaccine depending on the type. Please see below.

Type of Vaccine

Eligible Ages

Pfizer

12 and over

Moderna

18 and over

Vaccine effects

These vaccines are more effective than the originals against the Omicron variant.

Additional vaccines adapted for the Omicron variant contain components of this variant and produce a stronger immune response which contributes to protection against the development of the following due to Omicron: severe COVID-19, COVID-19 infection, and the development of symptoms. As such, in addition to being more effective than the original vaccine against the development of severe COVID-19 due to Omicron, it is expected to prevent infection and the development of symptoms, despite the possibility of offering protection for a short duration.

Bivalent vaccines are effective against many different COVID-19 strains

As the vaccines contain two different antigens, it is believed that the immune response produced is effective against many different strains of COVID-19. As such, there is a high possibility that the vaccines will be effective against new COVID-19 strains to come.

Vaccine safety (side effects)

In the pharmaceutical approval process of the bivalent vaccines from Pfizer and Moderna, both vaccines saw similar side effects to the original COVID-19 vaccine.

When will I receive my vaccine coupon?

Vaccination coupons for the original vaccine that you have already received can also be used for the Omicron-adapted vaccine. As such, for those who have already received vaccination coupons for their third or fourth dose, but have not yet received their vaccination, please use these coupons for your Omicron-adapted vaccine.

For those 12 and over who have received their first and second doses, but have not yet been sent vaccination coupons, we will begin sending them in mid-October.

  • Those who have not yet been sent a vaccination coupon for their third dose, and for whom it has been about 5 months since their second dose (those who completed their second dose by May 31, 2022)
  • Those who have not yet been sent a vaccination coupon for their fourth dose, and for whom it has been about 5 months since their third dose (those who completed their third dose by May 31, 2022)
  • Those for whom it has been about 5 months since their fourth dose (those who completed their fourth dose by May 31, 2022)

For later dates: those 12 and over who have completed both doses of the original vaccine will be sent vaccination coupons after it has been about 5 months since their last original vaccination.

Your vaccination coupon will come in a light pink envelope.

For those who have moved to Hiroshima City after receiving their previous vaccinations in another municipality must apply for their vaccination coupons. For more information, see here (Japanese).
