EU regulator launches review of Pfizer-BioNTech’s adapted COVID-19 vaccine

210

The European Medicines Agency (EMA) has announced a rolling review of a variant-adapted COVID-19 vaccine from Pfizer and BioNTech.

The 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 and 5 that are currently behind most cases in Europe.

Meanwhile, European Union officials say they plan to use bivalent shots in their autumn vaccination campaign, with most cases in the region now linked to the BA.5 variant.

Last month, the EMA said it had begun a rolling review of another version of the companies’ shot which targets the original SARS-CoV-2 strain and Omicron subvariant BA.1.

While existing coronavirus vaccines continue to provide good protection against hospitalization and death, vaccine effectiveness has taken a hit as the virus has evolved.

European Union officials plan to use bivalent shots in their autumn vaccination campaign, with most cases in the region now linked to the BA.5 variant.

The EMA expects new COVID variant-adapted vaccines to be approved by September, but has signaled it is open to using shots targeting the older BA.1 variant for that campaign, given the shots targeting the newer BA.4 and BA.5 strains are further behind in clinical development.
