Immunization Requirements

All students of the Williamsville School District must meet immunization requirements of New York State Public Health Law.   The New York State Health Department issued new immunization requirements for school entrance/attendance for the 2020-2021 school year, please see New York State Immunization Requirements for School Entrance/Attendance footnotes for a complete list of immunization requirements with vaccine specific footnotes.  


**NEW** On June 13, 2019, New York Governor Andrew Cuomo signed legislation removing non-medical exemptions from school vaccination requirements for children. There is no longer a religious exemption to the requirement that children must be vaccinated against measles and other diseases to attend public, parochial, or private school, or child day care settings. For more information from New York State about the new legislation, read the documents linked below:

Please work with your child’s health care provider and school nurse to determine what immunizations are needed to comply with the new vaccine requirements.  

These minimum requirements include:

  1. Diphtheria and Tetanus-containing vaccine and Pertussis vaccine (DTaP/DTP/Tdap): three doses, grades 6 through 12; three to five doses, grades K through 5.
  2. Tetanus and Diphtheria toxoid-containing vaccine and Pertussis booster (Tdap): one dose, students eleven years of age or older enrolling in grades 6 through 12 who have not previously received a Tdap at 7 years of age or older.
  3. Polio vaccine (IPV/OPV): four doses, grades K through 12, unless third dose was received at four years of age or older.
  4. Measles, Mumps and Rubella vaccine (MMR): two doses, grades K through 12.
  5. Hepatitis B vaccine: three doses, grades K through 12.
  6. Varicella (chickenpox) vaccine: two doses, grades K through 12 OR documentation of positive disease history from the health care provider.
  7. Meningococcal type A, C, W and Y (MenACWY) vaccine: one dose, grades 7 through 11; two doses, grade 12 with one dose on or after the age of sixteen.

Demonstrated serologic evidence of measles, mumps, rubella, hepatitis B, varicella or *polio (must be for all three serotypes) antibodies is acceptable proof of immunity to these diseases.  Diagnosis by a physician, physician assistant, or nurse practitioner that a child has had varicella disease is acceptable proof of immunity to varicella.

Please note: *Polio serology to all three polio serotypes is no longer available in the United States and is not an acceptable proof of immunity unless the serology testing was performed prior to September 1, 2019 and demonstrated positive immunity to all three polio serotypes
