Johnson & Johnson vaccine pause leaves gaps in vaccine distribution April 19, 2021 8:30 PM Madalyn O'Neill Updated: In Iowa County, there’s already a gap between vaccine supply and demand. “We seem to have more demand than we have vaccine at this point,” Emergency Management Director Keith Hurlbert said. “Our allocations have been rather small. In the last few weeks, even smaller — a little frustrating from that standpoint. Now with the Johnson & Johnson issue, smaller yet.” That translates to a bigger gap and fewer vaccinations. Hurlbert said last week’s total allotment included 140 Moderna doses and 100 Johnson & Johnson doses, now waiting in storage. That meant canceling appointments and shifting those they could to the Moderna vaccine.
