How COVID-19 Affects Children

While children have been less affected by COVID-19 compared with adults, children can get sick from COVID-19 and can spread COVID-19 to others. Children with underlying medical conditions are at increased risk for severe illness.

  • Cases of COVID-19 among children have increased in the U.S., especially with widespread transmission of the highly infectious Delta variant.
    • As of October 2021, there have been more than 1.9 million cases of COVID-19 among children ages 5-11 in the U.S. since the onset of the pandemic, according to the CDC.
    • As of October 2021, there have been more than 39,200 cases of COVID-19 among children ages 5-11 in Colorado, and more than 210 children have been hospitalized due to COVID-19, according to CDPHE. 
    • As of October 2021, there have been more than 3,100 cases of COVID-19 among children ages 5-11 in Jefferson County. For more Jeffco data, visit our COVID-19 Data Dashboard.
    • According to the American Academy of Pediatrics, currently about 1 in 4 cases of COVID-19 in the U.S. are among those ages 17 and younger.
  • Though it is very rare, some children who have had COVID-19 may later develop Multisystem Inflammatory Syndrome in Children (MIS-C), a serious condition associated with COVID-19.

Facts About the COVID-19 Vaccine for Children

CDC recommends that everyone 5 years and older get a COVID-19 vaccine to help protect against COVID-19. Children 5-11 years old are now able to get the Pfizer-BioNTech COVID-19 vaccine. 

  • The Pfizer-BioNTech COVID-19 vaccine for children is a two-dose series given about three weeks (21 days) apart. The vaccine dose for children (10 micrograms) is a third of the vaccine dose used among individuals ages 12+ (30 micrograms).
  • The vaccine for children ages 5-11 was about 90% effective in preventing COVID-19, and 100% effective at preventing severe disease and death.  
  • Immune responses of children ages 5-11 were comparable to those of individuals ages 16-25. 
  • The vaccine’s safety was studied in approximately 3,100 children ages 5-11 who received the vaccine and no serious side effects have been detected in the ongoing study, including no cases of myocarditis or pericarditis.
  • Side effects (normal signs that your body is building protection) among children were similar to those among adults. They can include tiredness, headache, soreness, chills, and fever. In clinical trials, children ages 5-11 tended to have milder side effects than teens and adults. Most side effects are mild and go away on their own after a day or two.
  • COVID-19 vaccines and other vaccines, such as flu or other routine childhood vaccines, can be administered together.
