The European Medicines Agency (EMA) will likely decide in early October whether to endorse a third dose of the Pfizer-BioNTech, COVID-19 vaccine to be given half a year after the initial two-shot course.

“The outcome of this evaluation is expected in early October, unless supplementary information is needed,” the European Medicines Agency’s (EMA) head vaccines strategy, Marco Cavaleri, told a press briefing on Thursday.

Reuters reported earlier in the day that EMA expects to come to a conclusion on booster doses in early October.
