COVID-19 Vaccines Approved for Children Starting at Six Months

Children ages 6 months to 5 years can now get COVID-19 vaccinations. Two vaccines received emergency use authorization (granted when a drug is needed for emergency use) by the Food and Drug Administration (FDA). Pfizer and Moderna vaccines are available for children 6 months and older.

Data shows the vaccine provides many benefits and is the way to end the COVID-19 pandemic. According to the Centers for Disease Control and Prevention (CDC), “everyone 6 months and older, including those with disabilities and underlying medical conditions, should get vaccinated against COVID-19.” Parents may still question the need and safety of the vaccine for young children.

What are the Benefits of Younger Children Receiving the Vaccine?

While many children have mild symptoms with COVID-19, a small number need more serious medical care. This may include being admitted to the hospital or an intensive care unit. Research has proven that the benefits of the vaccine for younger children outweigh the risks, and while no vaccine is 100% effective, the COVID-19 vaccine reduces the risk of the harmful effects of COVID-19.

What Is the Difference Between Pfizer and Moderna Vaccines for children under 5?

There are slight differences in the dosing regimen for each product. With the latest update to the CDC recommendations, these differences have become less significant.

Will My Young Child Need Booster Shots?

Booster shots are recommended for children over 6 months of age who have not yet received a bivalent vaccine dose.

Where Is the Shot Given?

Younger children receive many vaccines in their thigh because it is a bigger muscle to receive the shot.

Is the COVID-19 Vaccine Safe? What Are the Side Effects in Young Children?

Vaccines have been studied in every age group to make sure they are safe and effective. Common side effects include pain and tenderness at the injection site, irritability and fever. These effects are due to the body’s immune system building immunity to COVID-19. These symptoms usually are better within 24 to 48 hours. Some children don’t have any side effects.

My Child Already Had COVID-19. Do They Still Need to Be Vaccinated?

Yes. It is possible to get COVID-19 again, so it’s important for your child to be vaccinated even if they have already had COVID-19.

How Soon Does the Vaccine Work?

Children are considered fully vaccinated about two weeks after their final dose.

Can Children Get Really Sick With COVID-19?

Children are at lower risk of becoming severally ill with COVID-19 compared to adults, however it is possible for children infected with COVID-19 to get very sick. One serious effect is multi-system inflammatory syndrome (MIS-C). MIS-C occurs in children who previously were infected with COVID-19. It causes different body parts to become inflamed, including the heart, lungs, kidneys and brain. 

Where Can My Child Get Vaccinated?

Check with your child’s doctor to determine the best place to have your child vaccinated.
