About COVID-19 vaccinations for young children (ages 5-11)
Young children between the ages of 5 and 11.
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.
Vaccine type and interval between doses
Vaccine type and interval between doses
Interval between first and second doses of primary vaccination series
Interval between last dose received and first vaccine booster
|Pfizer vaccine for children (*1)|
Normally at least 3 weeks (*2) after the first dose
5 months after the second dose
(*1) Children 12 and older use a different vaccine, along with different directions and dosage.
(*2) Even if the standard 3-week waiting period between shots has passed, the second shot can be taken. There is no need to start over and get the first shot again, so it is recommended that to get the second shot as soon as possible.
[About vaccines for influenza, etc., and the interval between doses of other vaccines]
- Doses of the COVID-19 vaccine and influenza vaccines may be taken at the same time with no waiting period.
- Generally vaccines other than the influenza vaccine may not be taken at the same time. Either the other vaccine or the COVID-19 vaccine may be taken if an interval of 2 weeks has passed.
Parent or guardian must consent and accompany the young child for them to get the vaccine
Parents and guardians are asked to ensure they are familiar with accurate information related to both the vaccines’ efficacy and risks and to discuss vaccination with their child before they make the decision to vaccinate or not. Vaccinations will not be administered without the guardian’s consent. Forcing people around you to be vaccinated or showing discriminatory treatment to those who have not been vaccinated is unacceptable.
Potential side effects after getting the shot (side reactions)
- COVID-19 vaccines have been seen to sometimes cause side effects after they are administered, such as pain around where you were given the shot, headaches, fatigue, muscle and joint pain, chills, diarrhea, or fever. In very rare cases, recipients may experience severe symptoms such as shock or anaphylaxis. Also, as this is a newly developed vaccine, there is a possibility that other unexpected symptoms may be experienced. If you are concerned about a symptom that occurs after getting the vaccine, please consult the vaccinating doctor or your regular doctor.
- Compared to the second dose of the primary vaccination series, more recipients (2% of cases) of the vaccine booster have reported swelling in the lymph nodes under the armpit. While symptoms appear within two days of getting the shot, and most are light to moderate and full recovery is seen in about one week, if symptoms persist or become severe, please visit a doctor or health care facility.
- After getting the first or second dose of vaccine, there have been reports of extremely rare cases where recipients developed myocarditis or pericarditis. If the recipient, within a few days of getting the vaccine, experiences chest pain, heart palpitations, shortness of breath, or swelling, consult a doctor or health care facility immediately.
- While extremely rare, there have been reports of developing symptoms of Guillain–Barré syndrome after receiving the mRNA-type vaccine. After getting the vaccine, if the recipient has a hard time moving their arms or legs, or experiences numbness in their extremities, consult a doctor or health care facility immediately.

Vaccine guidance for children who will soon turn 12 years old (currently 11 years old)
Depending on the timing of the vaccination, the vaccine used may be different.
- If the child had their first dose at 11 and will have their second dose after turning 12, the children’s version of the vaccine will be used for both doses.
- If the child is already 12 by the time of the first dose, the first and second doses will both use the adult’s version of the vaccine.
- Note that for the purposes of the vaccination, children will be considered 12 years old as of the day before their birthday.
