"Interim statement on COVID-19 vaccination for children and adolescents" 24 November 2021
This statement was updated on 29 November 2021 to correct some references and associated linksBackground
Although the majority of COVID-19 vaccines are only approved for use in adults aged 18 years and above, an increasing number of vaccines are now also being authorized for use in children. Some countries have given emergency use authorization for mRNA vaccines for use in the adolescent age group (aged 12-17 years): BNT162b2 developed by Pfizer, and mRNA 1273 developed by Moderna. In November 2021, one stringent regulatory authority approved the mRNA vaccine BNT162b2 for the use in children aged 5-11. Trials in children as young as age 3 years were completed for two inactivated vaccines (Sinovac-CoronaVac and BBIBP-CorV) and these products were approved by Chinese authorities for the age indication of 3-17 years; although these vaccine products have received EUL for adults, they have not yet received WHO EUL for children. Covaxin, an adjuvanted inactivated vaccine developed by Bharat, was approved in India for the age indication of 12-17 years; but not yet received WHO EUL for this age indication. The Indian regulatory authorities have given approval to ZycovD, a novel DNA vaccine, for ages 12-17 years; however, this vaccine has not yet received WHO EUL. Several COVID-19 vaccines are undergoing trials in younger age groups (including as young as 6 months of age), but results have not yet been published. "
