Parents say they are confused with how their kids with out-of-date vaccines are being handled by Long Island school districts.

Hundreds of students were sent home this week for not complying with the state law that got rid of all religious exemptions.

However, the change is also affecting kids who are vaccinated but aren't up-to-date.

Lauren Gonzalez says her son has always been vaccinated. She says he's missing the one he's supposed to get this year because they couldn't get an appointment fast enough. 

According to a letter from the Middle Country Central School District, proof of an appointment was acceptable to allow her son continue school. Gonzales said after she sent the letter, the school district then said the plan for the appointment was no longer enough.  Now her son is home until he can get his shot.

Rita Palma, from Children’s Health Defense says the New York Education Department, has failed to help schools handle out-of-date vaccinated students.

“The New York State Education Department is not keeping its schools up-to-date on the details of how to actually implement this law. The result is confusion and kids are traumatized over it,” she says.

Superintendent of Schools Dr. Roberta Gerold sent out a statement, saying, “As noted in a letter sent out to the community last week, the Middle Country Central School District is obligated to adhere to and enforce all immunization regulations set forth by New York state. Although appointment cards are still accepted as proof for multiple-dose vaccinations, under the law, one time vaccinations like Tdap now needs to be administered prior to the specified exclusion date.

Dr. Gerold added, “In reviewing the wording of the district’s letter, we realize this may not have been made absolutely clear. However, the district has no authority to deviate from these regulations but promises to support students and families through this transitional period.”
