Since the start of the pandemic, more than 13 million children have tested positive for COVID-19 in the United States, and nearly 1,600 children died from the virus or complications from multisystem inflammatory syndrome (MIS-C). However, now we have COVID-19 vaccines that have proven to be safe and effective, and help prevent severe disease, hospitalization, and death from COVID-19.

Children ages 6 months and older are now eligible to receive a COVID-19 vaccine and updated booster dose. The Centers for Disease Control and Prevention (CDC) recommend that all eligible children receive a COVID-19 vaccine and that children who have already had COVID-19 get vaccinated.

COVID-19 Vaccination

The Pfizer-BioNTech and Moderna COVID-19 vaccines are available for children 6 months to 17 years of age. The Food and Drug Administration (FDA) authorized emergency use authorization (EUA) for both COVID-19 vaccines in chlidren aged 6 months to 5 years on June 17, 2022. 

COVID-19 vaccines are administered as follows:


  • 6-month-olds to 17-year-olds: A primary series of two doses is administered four to eight weeks apart.
  • Immunocompromised: A third dose can be given at least four weeks following the second dose.

 Dosages vary by age:

  • 6-month-olds to 5-year-olds receive 25 micrograms per dose of vaccine.
  • 6- to 11-year-olds receive 50 micrograms per dose.
  • 12- to 17-year-olds receive 100 micrograms per dose.


  • 6-month-olds to 4-year-olds: A primary series of three doses, with the first two doses administered three to eight weeks apart, and a third dose administered at least eight weeks after the second dose.
  • 5- to 17-year-olds: A primary series of two doses is administered three to eight weeks apart.
  • Immunocompromised: A fourth dose should be administered at least four weeks after the third dose for children who are immunocompromised.

Dosages vary by age:

  • 6-month-olds to 5-year-olds receive 3 micrograms per dose of vaccine.
  • 6- to 11-year-olds receive 10 micrograms per dose.
  • 12- to17-year-olds receive 30 micrograms per dose.

Side Effects

Common side effects tend to be mild and temporary. They include fever, headache, chills, tiredness, muscle and joint pain, and pain at the injection site.

Updated COVID-19 Booster Vaccines

Children aged 6 months and older who completed the Moderna COVID-19 vaccine primary series can now get an updated COVID-19 booster dose. The FDA approved this age group on December 9, 2022 for the Moderna and Pfizer-BioNTech COVID-19 vaccines. The updated COVID-19 vaccines include the Omicron BA.4 and BA.5 to "help resore protection that has waned since previous vaccination and targeting recent Omicron variants that are more transmissible and immune-evading."


  • Children ages 5 years and older can receive the updated COVID-19 booster dose two months after the two-dose primary vaccine series or two months after receiving a COVID-19 booster shot.


  • Children ages 6 months and older can receive the updated COVID-19 booster dose two months after the two-dose primary vaccine series or two months after receiving a COVID-19 booster shot.

Child Immunizations

In May 2021, the CDC updated its guidance for immunization services during the COVID-19 pandemic. The CDC recommends children can receive COVID-19 vaccines with other vaccines, such as HPV and Tdap, without having to wait between vaccines. The American Academy of Pediatrics (AAP) also supports co-administration of routine childhood and adolescent immunization with COVID-19 vaccines.

Routine vaccination is an essential preventive care service that should not be delayed for any age group. According to the CDC, routine vaccination helps prevent illnesses and helps protect individuals and communities from vaccine-preventable diseases and outbreaks. The CDC says the interim guidance will be continually reassessed and updated based on evolving epidemiology of COVID-19 in the US.

COVID-19 Facts

There are many damaging myths about COVID-19, vaccines, and children that are preventing people from getting the protection they need. Anyone with questions should talk with a trusted, licensed health care provider.

FACT: Children can spread COVID-19.

Early studies suggested children did not play a big role in the spread of COVID-19 and did not seem to get infected as often. However, more recent studies found some children carry equally high levels of SARS-CoV-2 and can spread it easily to others. This has always been true for older children. According to Andrew Pavia, MD, chief of the Division of Pediatric Infectious Diseases at University of Utah Health, most hospitalizations and serious complications from COVID-19 have been among kids 12 to 18 years old.

FACT: COVID-19 is a serious virus for children.

While the earlier strains of the COVID-19 virus did not impact children as much as adults, COVID-19 hospitalizations for children under 18 have soared with more transmissible and contagious strains. Children are at risk of experiencing complications such as hospitalization, death, and perhaps most commonly, long COVID. The number of children hospitalized in Utah and other parts of the country was unprecedented during the fall wave of Delta and the winter wave of Omicron, according to Pavia.

Another condition among children caused by COVID-19 is MIS-C, a serious illness that causes harmful inflammation in different parts of the body. It takes three to six weeks after infection for the condition to develop. “One of the scary things about long COVID is it doesn’t seem to matter how sick you get when you are originally infected,” Pavia says. “Vaccines will help prevent that and also help prevent MIS-C because it occurs after COVID-19 infection.” Most children who develop MIS-C need to be treated in the hospital, with many in the ICU. 

FACT: It’s safe for kids to get vaccinated.

The side effects experienced among kids are nearly identical to those of adults. These include pain at the site of injection, headache, fever, and fatigue. Side effects typically last a day or two and can be treated with over-the-counter medications. Currently, the CDC is monitoring reports of myocarditis and pericarditis, an extremely rare and temporary condition associated with the Pfizer-BioNTech vaccine that may occur in less than .001% of vaccinated people. The CDC continues to highly recommend COVID-19 vaccines because the risk of severe illness and complications associated with COVID-19 infection far outweigh any potential risk from vaccination.

FACT: Three doses give better protection.

The initial COVID-19 vaccine series and a booster shot will better protect you or your child from severe disease, hospitalization, and death from the virus. “It’s become very clear that as the virus changed over time, immunity from natural infection and from the first two doses is waning,” Pavia says. A second booster is also available for certain groups and is recommended four months after the first booster dose. An additional booster dose helps further enhance protection against the COVID-19 virus.

FACT: COVID-19 vaccines don’t impact fertility.

There is no evidence that COVID-19 negatively affects fertility or menstrual cycles. COVID-19 vaccines are considered safe and effective for pregnant women, women who are breastfeeding, and women who would like to have babies. According to studies, people who are infected with SARS-CoV-2 during pregnancy are about 40% more likely to develop serious complications or die than those who aren’t infected with the virus.
