ECDC and EMA issue advice on fourth doses of mRNA COVID-19 vaccines

8. April 2022 – The European Centre for Disease Prevention and Control (ECDC) and EMA’s COVID-19 task force (ETF) have concluded that it is too early to consider using a fourth dose of mRNA COVID-19 vaccines (Pfizer’s Comirnaty and Moderna’s Spikevax) in the general population. However, both agencies agreed that a fourth dose (or second booster) can be given to adults 80 years of age and above after reviewing data on the higher risk of severe COVID-19 in this age group and the protection provided by a fourth dose.
