A mother says her daughter's Sound Beach school is trying to force her to give her child a vaccination that she claims the girl is too young to receive.

Jamie McNicholas says her daughter Ceili was fully vaccinated before she started third grade at Laddie A. Decker Sound Beach School this school year. However, because of a change in immunization requirements concerning pertussis, Ceili is now considered undervaccinated.

According to New York state law, the CDC and the American Academy of Pediatrics, she needs a booster in order to attend school. Without it, her mother says Ceili will not be permitted back to school on Nov. 17.

McNicholas says that when she took her daughter to the pediatrician, the doctor told her she'd have to sign a consent form because, according to the manufacturer, the vaccine called Boostrix is approved for use in individuals ages 10 and older.

The Miller Place School District says it is only enforcing regulations set by the state's Education and Health departments. The Health Department says it follows guidelines from a federal advisory committee for the CDC. However, the FDA - which is also a federal agency - confirmed that it approved the booster for kids ages 10 and up.

News 12 called seven pediatricians from across Long Island, all of whom said they give the booster to kids older than 10. Not one of the doctors said they would give it to an 8-year-old.
