EU health agencies said on Wednesday there was no evidence to support the use of a fourth dose of COVID-19 vaccines developed by Pfizer and Moderna in the general population, but they recommend a second booster for people aged 80 and above.

There is no clear evidence in the European Union that vaccine protection against severe disease is waning substantially in adults with normal immune systems aged 60-79, the European Medicines Agency (EMA) and the European Center for Disease Prevention and Control (ECDC) said in a joint statement.
