Requires automatic registration with New Jersey Immunization Information System upon administration of vaccine for certain persons who consent to registration.

This bill requires that anyone receiving a vaccine in New Jersey who is not already registered in the state's Immunization Information System (NJIIS) be automatically added to the system at the time of vaccination, unless they or their parent/guardian (for minors) provide a written request to opt out. It directly affects all New Jersey residents receiving vaccines who aren't already enrolled, including children and adults. The key provision eliminates the need for separate enrollment by linking registration to the vaccine administration event, with a simple written opt-out option. The system is designed to centralize vaccination records for public health purposes like outbreak response and school enrollment verification, while ensuring individuals can decline participation.
