Even as DCH Health System expands COVID-19 vaccinations into the 1A plus crowd adding police, firefighters, and those over 75 to the 1A designation of healthcare workers and those in communal living it could potentially double the 800 shots it s delivering per week, if more of the Pfizer vaccine doses were available. We have the capacity at DCH to offer many more appointment times than we are currently, said Andy North, DCH vice president of marketing and communications. The appointment book is filled every week through February, and into the first days of March. What we know at this point is as we use up the vaccine, and report back our usage rate, that makes us eligible to get more vaccine, if there is any, North said.
