CHARLOTTE, N.C. -- The Mecklenburg County Department of Health says patients who were treated following a Hepatitis A scare may have received the wrong dosage.

About 2,000 people received vaccines in April after officials said a Papa John s employee was exposed to the disease in an overseas trip.

The health department now says a small number of people were inadvertently given the incorrect dose. In some cases, children were given the amount prescribed for an adult, and adults were given children s vaccines.

There is no known risk associated with this mix-up, according to the health department. However, adults who received a child s vaccine are asked to return for a correct dose.

About two dozen people will need to be revaccinated. They have been contacted by the health department.
