9 August 2022 - The EMA has started a rolling review of a variant-adapted COVID-19 vaccine from Pfizer and BioNTech, it said on Tuesday.
The so called bivalent vaccine targets two strains of the SARS-CoV-2 virus behind COVID - the original strain first identified in China, and the Omicron offshoots BA.4/5 that are currently behind most cases in Europe.
