Mass. Company Making Ultra-Cold Freezers to Store COVID Vaccine Seeing Huge Demand

A Massachusetts company is playing a key role in the nation’s coronavirus response. Waltham-based Thermo Fisher Scientific has already helped with testing and protective gear, but now the company is making freezers to store the vaccine.

One of the vaccines on the horizon made by Pfizer — an experimental new kind of vaccine made using mRNA molecules — has to be stored in extremely cold temperatures, minus-94 degrees Fahrenheit. After hearing that, engineers at Thermo Fisher started working overtime to produce the ultra-low temperature freezers needed to store them.
