In keeping with Stephane Bancel, chief govt at Moderna, it’s going to take a number of months earlier than pharma firms can manufacture variant-specific jabs at scale, The Monetary Occasions reported.

Certain,” mentioned Bancel, who predicted Moderna may make a complete of 2bn-3bn doses in 2022. However he mentioned it could be dangerous to shift Moderna’s total manufacturing capability to an Omicron-targeted jab at a time when different variants had been nonetheless in circulation.
