The EU’s drug regulator has expressed doubts about whether a second booster dose of the currently available COVID-19 vaccines would be a sustainable long-term approach.

“There is an emergency discussion around the possibility of giving a second booster dose with the same vaccine currently in use. Data has not yet been generated to support this approach,” Marco Cavaleri, the European Medicines Agency’s (EMA) head of vaccines strategy, told a media briefing.
