Vaccine for Kids

Last updated 2/3/2023

We know that your child’s health and safety matter most. Children ages 5 and older can get a vaccine and  booster.  Children ages 6 months to 4 years old are eligible to get a COVID-19 vaccine and may be eligible to get a booster, depending on which vaccine they already received.


You may have questions or concerns – that’s okay. We encourage you to review the information below and talk to your child’s doctor if you have more questions.

Vaccines are Safe & Effective

  • The COVID-19 vaccines have been rigorously tested and reviewed, and as with all vaccines, continue to be monitored for safety. Tens of millions of children and teens have safely COVID-19 vaccines.

  • Data from clinical trials shows that the vaccines are safe for younger kids.

    • Children may have mild side effects, such as a sore arm, fatigue, headache, or slight fever, and most pass in one or two days. These are normal signs that their body is building protection. Serious side effects are rare and treatable.

    • The vaccines greatly lower the risk of serious illness, long-lasting COVID-19 symptoms, hospitalization and death from COVID-19.

    • Vaccinated children are much less likely to get severely ill from COVID-19, including variants such as Omicron. That means they are less likely to miss school, sports and social activities.

  • You cannot get COVID-19 from the vaccine.

  • There is no evidence that the vaccine, or any other vaccines, cause fertility problems.

  • The risk of myocarditis (inflammation in the heart) is rare. In fact, getting COVID-19 increases the risk of developing myocarditis.

The Risk of COVID-19 to Children 

COVID-19 can make children and teens of any age very sick and can sometimes require treatment in a hospital. Some children and teens have even died from COVID-19.  Although children with underlying medical conditions are more likely to get severe COVID-19, healthy children without underlying conditions can also experience severe illness.​


The best way to prevent your child from getting really sick from COVID-19 is to keep them up to date on their COVID-19 vaccination and boosters. Since the Omicron variant became dominant, children ages 5-11 who are unvaccinated are twice as likely to be hospitalized than children who are vaccinated. Prescription treatment medications, such as Paxlovid, that help people with COVID-19 recover are not yet authorized for children under 12.

About the Vaccines

Dosage for all COVID-19 vaccines is based on your child’s age on the date of vaccination, not by their weight or size. The dosage is smaller than the one given to people ages 12 and older (adult dosage).

    • Your child will need 2 doses of the vaccine given 3 weeks apart, followed by a third dose, the omicron booster, 2 months later

If Your Child is Feeling Nervous

  • Think about when to tell them about their appointment. Some experts recommend one day ahead for every year of life.

  • Calmly tell them what will happen during the appointment.

  • Use neutral language like “vaccine” instead of "shot” and “pinch” or “pressure” instead of “poke.”

  • Encourage them to ask questions, express their feelings, or role play with their toys.
