COVID-19 Vaccines For Children

Vaccines have significantly reduced many childhood diseases, says the U.S. Food and Drug Administration (FDA). Vaccines prevent infectious diseases in babies, children, and adolescents. 

The U.S. CDC recommends everyone ages 5 and older get a vaccine to help protect against severe COVID-19. Eligible children can receive reduced dosages of the mRNA COVID-19 vaccine. However, when turning 12 years old, they should receive the full, adult dosage.

According to the CDC, as of November 24, 2021, there have been 621 deaths attributed to COVID-19 (vaccination and comorbidity status undisclosed) in people under 18 in the U.S. since January 2020. Additionally, the CDC reported 170 deaths involving both COVID-19 and pneumonia. The CDC publishes current 'COVID-19 Weekly Deaths by Age, Race/Ethnicity, and Sex' trends on this webpage.

Moreover, the CDC recently confirmed 'Rare serious adverse events have been reported after COVID-19 vaccination, myocarditis after Comirnaty (Pfizer-BioNTech) and SpikeVax (Moderna) COVID-19 vaccination. On November 19, 2021, the CDC vaccine committee reviewed additional heart-risk data after mRNA vaccinations.

The WHO reported on November 24, 2021, 'Although benefit-risk assessments clearly underpin the benefit of vaccinating all age groups, including children and adolescents, the direct health benefit of vaccinating children and adolescents is lower compared with vaccinating older adults due to the lower incidence of severe COVID-19 and deaths in younger persons. Safety signals such as myocarditis, albeit rare, are reported more frequently in young persons aged 16-24 years, particularly males. The risk of myocarditis in adolescents and/or children has not yet been determined.'

The U.K.'s Joint Committee on Vaccination and Immunisation is recommending one dose to people under 15 years of age. A paper recently published by the Oxford Vaccine Group presents a global dataset that looks at childhood vaccination policies worldwide.
