NORWOOD (CBS) – Moderna is expanding its manufacturing plant and laboratory in Norwood.

The Cambridge-based company said Tuesday the space will more than double from approximately 300,000 square feet to 650,000 square feet as it ramps up production of its COVID-19 vaccine there.

They hope the expansion will help them develop better shelf-life stability for their vaccines and new ways to deliver them with prefilled syringes.

Moderna opened the Norwood site in July 2018. Staff
