To help students fulfill immunization requirements needed before May 1 to stay in class, the Pennsylvania Department of Health is offering free immunization clinics in all 60 counties.

The York County State Health Center, 1750 N. George St., is offering free immunization clinics from 11 a.m. until 7 p.m. daily through Friday.

The clinics are open to students in all school districts in York County, said Holli Senior, a state Department of Health spokeswoman. Students must be accompanied by a parent or guardian and should bring a copy of their most recent vaccination history.

Appointments can be made by calling 1-877-724-3258. Free immunizations are always available for underinsured and uninsured individuals, who can call the same number to schedule appointments to be vaccinated.

Before the May 1 deadline, parents of all school-age children in Pennsylvania must show school districts proof of vaccinations from a physician. The state has mandated that students will no longer be allowed to attend school if they do not present updated immunization records.

A religious exemption in the law allows children to continue attending school if a parent or guardian submits a written objection to the immunizations based on moral or ethical conviction. The only other exemption is for medical reasons.
