After weather delays, New Hanover County received a backlog of doses from last week as well as a hefty shipment for this week. Teacher vaccinations begin Wednesday. (Port City Daily/Courtesy New Hanover County) NEW HANOVER COUNTY — Following a week in which extreme weather disrupted the Covid-19 vaccine shipping process, New Hanover County received substantially more vaccines from the state than in recent weeks. The surplus includes 1,000 doses that should have arrived last week. As many as 2,340 doses of the Pfizer vaccine will be used to schedule appointments this week in the county. Federal guidelines have shifted, and the U.S. Centers for Disease Control and Prevention now advises that six, not five, doses can be pulled from a Pfizer vial.
