CHARLOTTE, N.C. - Health officials say more than 1,000 people have been given vaccinations against hepatitis A after an employee at a Charlotte pizza restaurant was hospitalized with the disease.

Health officials in Mecklenburg and Cabarrus counties are urging anyone who ordered or ate a pizza from the Papa John's on Cambridge Commons Drive between March 28 and April 7 to get the vaccine.

Free clinics have been giving shots throughout the weekend, and health officials say they have vaccinated more than 1,000 people.
