Student Immunization Requirements

The following immunizations are required at all CTY Summer Program sites:

  • 2 doses of MMR (measles, mumps, rubella) OR a titer showing immunity to all three diseases.
  • A tetanus booster within the last 10 years (this can be any immunization with tetanus: TT, Td, Tdap, DTaP).

These additional immunizations are recommended for all CTY students and required for students attending sites in Connecticut and New Jersey.

  • At least 4 doses of DTaP (or 4 if last dose was before age 7).
  • One dose of Tdap if the child has completed grade 7 or above.
  • 3 doses of IPV/OPV (Polio), with one having been given after 4th birthday.
  • 3 doses of Hepatitis B (with last dose on or after 24 weeks of age).
  • 1 dose of meningococcal if child is entering grade 8 or above.
  • 2 doses of varicella or verification of immunity (1 dose required in New Jersey; 2 doses required in Connecticut).
  • 2 doses of Hepatitis A, with first dose after 1st birthday (required in Connecticut).

CTY must have a complete immunization record for every student on file. Please provide dates for all vaccinations/titers, whether required or recommended. In the event of an occurrence of any vaccine-preventable disease, students without documented vaccination or other proof of immunity may be asked to leave the site.

In alignment with the American Academy of Pediatrics, CTY allows exemptions to our immunization requirements only for medical reasons. Medical exemptions require documentation signed by a licensed health-care provider.
