To demonstrate adequate immunization against each disease, a child must present the school with a certificate of immunization from a physician, nurse practitioner or physician assistant or public health official who has administered the immunizing agent(s) to the child. The certificate must specify the immunizing agent, the dosage administered and the date(s) on which it was administered.
In the absence of a certificate of immunization, the child must present the school with laboratory evidence demonstrating immunity or reliable documented history of immunity provided by a physician or other primary care provider.
