    Exceptions to Requirements:

    • Receipt of the dose up to (and including) 4 days before the birthday will satisfy the school entry immunization requirement.
    • Serological confirmation of immunity to measles, mumps, rubella, Hepatitis A, Hepatitis
      B, or Varicella, or serological evidence of infection is acceptable in lieu of vaccine.
    • Two doses of adult Hepatitis B vaccine (Recombivax is acceptable.) Dosage and type of vaccine must be clearly documented. (Two 10mcg./1.0 ml of Recombivax).
    • Serologic proof of immunity of previous documentation of previous Varicella (chicken
      pox) illness may substitute for vaccination. Previous illness may be documented with a
      written statement from a physician, school nurse, or the child’s parent or guardian
      containing words such as: “This is to verify that (name of student) had Varicella disease
      (chicken pox) on or about (date) and does not need Varicella vaccine.”
    • Hepatitis A vaccine is required for students attending a school located in a high incidence
      geographical area designated by the Texas Department of Health. Thirty-nine counties
      are affected by the Hepatitis A requirement including Bexar County.

    The law allows (a) physician to write a statement stating that the vaccine(s) required would be
    medically harmful or injurious to the health and well-being of the child, and (b)
    parents/guardians to choose an exemption from immunization requirements for reasons of
    conscience, including religious belief. The law does not allow parents/guardians to elect an
    exemption simply because of inconvenience (a record is lost or incomplete and it is too much
    trouble to go to a physician or clinic to correct the problem).

    For children needing medical exemptions, a written statement (or medical immunization
    exemption form obtained from the school nurse) should be completed by the child’s physician
    and submitted to the school. This exemption must be renewed yearly at the beginning of each
    new school year unless the physician documents the exemption is due to a lifelong condition.

    Instructions for the affidavit to be signed by parents/guardians choosing the exemption for
    reasons of conscience, including a religious belief can be found at or

    Students with exemptions can be excluded from attending school if an outbreak occurs.

    All immunizations should be completed by the first date of attendance. The law requires that
    students be fully vaccinated against the specified diseases. A student may be enrolled
    provisionally, if the student has an immunization record that indicates the student has received
    at least one dose of each specified age-appropriate vaccine required by this rule. To
    remain enrolled, the student must complete the required subsequent doses in each vaccine series
    on schedule and as rapidly as is medically feasible and provide acceptable evidence of
    vaccination to the school. A school nurse or school administrator shall review the immunization
    status of a provisionally enrolled student every 30 days to ensure continued compliance in
    completing the required doses of vaccination. If, at the end of the 30 day period, a student has
    not received a subsequent dose of vaccine, the student is not in compliance and the school shall
    exclude the student from school attendance until the required dose is administered.

    Since many types of personal immunization records are in use, any documentation will be
    acceptable provided a physician or public health personnel have validated it. The month, day
    and year that the vaccination was received must be recorded on all school immunization
    recreated or updated after September 1, 1991.
