The European Medicines Agency has proposed to extend the use of two messenger RNA (mRNA) vaccines for Covid-19 in order to give protection against the SARS-CoV-2 virus to younger people. In separate decisions, the agency is recommending that primary vaccination with Spikevax be approved for use in children from the ages of six to 11 years. Spikevax was developed by Moderna Inc. The agency is also proposing that Comirnaty, developed by BioNTech SE and Pfizer Inc, be authorised as a booster dose for adolescents from 12 years of age.
