Hospitals across Connecticut are scrambling to catch up with COVID-19 vaccinations as there are new fears of strains coming out of the U.K. and other countries.

Monday's snowstorm forced more than 10,000 people to postpone their appointments.

Hartford HealthCare, which owns St. Vincent's Medical Center in Bridgeport, got to work right away.

"We knew about the storm coming," says Dr. Corina Marcu. "We knew the hours that we were scheduled to operate, so we just decided when it's safe to close the clinics, so people will not put themselves in harm's way."

Yale New Haven Hospital had to reschedule 2,000 patients. The hospital won't reopen until Wednesday but says it's confident it can get caught up by the end of this week.

"We actually had some open days where our mass vaccination sites were not currently operating, so we were actually just able to move the days from Monday and Tuesday into those unused days," says Dr. Ohm Deshpande.

The state's biggest mass vaccination site at Pratt and Whitney in East Hartford is back up and running - and time is critical.

"Another eight were diagnosed over the weekend, bringing us to a total of 16," says Gov. Ned Lamont.

He says that over the weekend, Connecticut doubled its cases of the new and more contagious COVID-19 strain.

"It's a unique moment in time right now. And we need everyone to do everything we possibly can to get us caught up before the end of the week," says Connecticut COO Josh Geballe.

Clinics tell News 12 they can meet that goal and get caught up by the end of the week.

Currently, only people 75 and older can get the vaccine. Those 65 and older will be able to get their vaccine in the next two weeks.
