Vaccine booster shots are available for all people who are 12 or older, have completed their primary two doses of the COVID-19 vaccine, and had their last dose at least three months ago.
Vaccinations will be administered using public funds, and are free of charge for everyone.
*However, there is a possibility you will have to pay for doctor fees if you visit a clinic before or after the vaccination.
About the type of vaccine used, the interval between doses, and eligibility by age
Regardless of the type of vaccine of the last dose you received, booster shots will use the Omicron-targeting vaccine made by Moderna or Pfizer.
Type of vaccine used, the interval between doses, and eligibility by age
|Vaccine used||Interval between doses|
|Pfizer||3 months since last dose||Ages 12+|

[About vaccines for influenza, etc., and the interval between doses of other vaccines]
