Pfizer/BioNTech Vaccine
The news was welcomed by heath experts around the world.
"With this particular vaccine, no corners were cut," Senior Vice President of Global Drug Safety Research and Development for Pfizer, John Burkhardt, said. Burkhardt is also the director of Pfizer's lab site in Groton.
About 200 employees are working on this vaccination project in Groton, according to Burkhardt.
"I'm really proud of the way Groton plays a role in this," Burkhardt said.
A logistical challenge with the vaccine is keeping it cold.
"We are working very hard on that. There is a whole fleet of experienced and talented people at Pfizer who are working on this," Burkhardt said.
A major factor when the vaccine comes out is to decide who has the capacity to store it and who will be capable to store it at low temperatures, according to Trinity Health of New England president & CEO Dr. Reginald Eadie.
Priority will be given to health care workers, first responders and people at high risk in the state, Eadie said.
Eadie is a co-chair of the governor's COVID-19 vaccine advisory group.
