Download This Pamphlet about Holly’s Law (the Anti-Body Blood Titer Test) from the New Jersey Health and Senior Services Department website. The information found in the pamphlet is provided to every health care provider in the state of NJ who administers the MMR vaccine and should be given to parents whose children are between the ages of 4 and 6. If the information is not provided by your physician, you should inquire about this test prior to giving your child the second MMR. If your child has a positive titer level because of the first MMR, you may present the titer levels to the school. Do you believe in giving your child unnecessary medication? If not, then before vaccinating, educate yourselves by utilizing many different sources, your physician, other parents who are vaccine knowledgable and the National Vaccine Information Center Website.
