British drugmaker AstraZeneca said Wednesday that it has withdrawn its COVID-19 vaccine Vaxzevria, one of the first produced in the pandemic, citing “commercial reasons” and a surplus of updated jabs.

“As multiple, variant COVID-19 vaccines have since been developed there is a surplus of available updated vaccines. This has led to a decline in demand for Vaxzevria, which is no longer being manufactured or supplied,” an AstraZeneca spokesperson said.
