Covid-19 vaccines are safe and effective. They help prevent children from getting infected, and lower the risk of serious illness if they do.
Who should get vaccinated?
All children over 6 months old in the United States can get Covid-19 vaccines. Children over the age of 5 can also get booster shots.
Primary series: the first set of doses of a vaccine needed to vaccinated against a disease
Booster shots: an additional dose or doses of a vaccine given after the protection from the original shot(s) begins to decrease.
- Earlier booster shots are called “monovalent.” They were designed to protect against the original virus that causes Covid-19.
- The updated boosters are called “bivalent” because they protect against the original virus that causes Covid-19 and the omicron variants BA.4 and BA.5.
What vaccines are available for children?
- Pfizer-BioNTech mRNA vaccine (6 months and up) and booster (5 years and up)
- Moderna mRNA vaccine
- Novavax protein subunit vaccine (12 years and up)
These vaccines are free and available to everyone, regardless of insurance coverage or immigration status.
Can children mix and match mRNA vaccines?
The CDC recommends completing a primary series with the same product whenever possible.
After completing the series and booster(s), keep checking with your child’s healthcare provider or the CDC to find out if and when they need to get another dose.
When should children get each dose?
- Ages 6 months to 4 years
- 2 doses of the Pfizer monovalent vaccine, 3-8 weeks apart
- A 3rd dose, which will be the bivalent vaccine, 8 weeks later
- Ages 5 years and older
- 2 Pfizer doses separated by 3-8 weeks
Ages 6 months to 4 years
No booster is recommended
1 bivalent Pfizer booster dose at least 2 months after 2nd primary series dose or monovalent booster
1 Pfizer or Moderna bivalent booster at least 2 months after 2nd primary series dose or monovalent booster
- Ages 6 months to 17 years
- 2 doses separated by 4-8 weeks
- Ages 6 months to 4 years

Immunocompromised children may need to follow a different vaccination schedule. Talk to your child’s healthcare provider to find out what is best for them.
