According to Amanda Harris of the Charlotte North Carolina Observer, at least 1,650 Charlotte residents sought hepatitis A vaccines after being exposed at the Papa John’s at 8016 Cambridge Commons Drive, where an employee was recently diagnosed with the virus.

Residents flocked to the clinic at the Cato campus of Central Piedmont Community College on Sunday.  The clinic saw about 350 people over roughly 4 1/2 hours, said Rick Christenbury, a Mecklenburg County spokesman.

The Health Department location at 2845 Beatties Ford Road will operate extended hours on Monday to accommodate walk-ins and will be open from 8 a.m. to 8 p.m.

Anyone who ate at the Papa John’s on Cambridge Commons Drive between March 30 and April 7 should get a hepatitis A vaccination, Christenbury said. The vaccine is effective for those exposed within the last 14 days.
