The keynote speaker at yesterday's Greater Danbury Chamber of Commerce annual meeting was Nuvance Health president and CEO Dr. John Murphy.  He told the virtual audience that the idea is to “checkmate” coronavirus so it can’t move around the population further.  He addressed a question on most people's minds--a vaccine.  Murphy says there are possible ones in phase three trials, but the likelihood was slim that one would be ready for use “right around the corner.”  He noted that the production of a vaccine has been fast tracked compared to how long it took to create Ebola and polio vaccines from the time they were first identified.
