Joseph: It’s at least the second time you mention parents falsifying their kids’ immunization records. Almost impossible to do in NY, not sure about NJ.
In NYS, I the schools have direct access to vaccination records entered by all doctors/pediatricians to the Health Depts.’ web site. So unless one has a doctor willing to enter false information, the schools will find out the truth when they log in. Below I copy-pasted from the NY DoH website. You can easily find the full text.
As part of this effort, the New York State legislature passed the Immunization Registry Law which, as of January 1, 2008, requires health care providers to report all immunizations administered to persons less than 19 years of age, along with the person’s immunization histories, to the New York State Department of Health using the New York State Immunization Information System (NYSIIS).
