People who lost COVID vaccines because of double-bookings will get new dates, Murphy said Updated Jan 29, 2021; The problem caused the state to “cancel a number of appointments that were erroneously double-booked,” he said. “We will work with those canceled on rescheduling their appointments at the nearest available time,” he said. “We regret the confusion this technical issue caused, and we are working with our vendor - and as you can imagine the conversations are spirited - to address the root cause and that this does not happen again.” David Adinaro, the health department deputy commissioner, said they believed the booking issue was specific to the Gloucester site.
