(1) Before a prospective pupil may attend a Montana preschool, that school must be provided with adequate documentation that the prospective pupil has been immunized in accordance with the following standards:
(a) the prospective pupil must have received three doses of polio vaccine and four doses of DTP/DTaP vaccine or DT vaccine, subject to the requirement that DT vaccine administered to children is acceptable only if accompanied by a medical exemption for that prospective pupil from pertussis vaccination;
(b) the prospective pupil must receive one dose of MMR vaccine, administered no earlier than 12 months of age;
(c) one dose of Hib vaccine must be administered on or after the first birthday, unless the prospective pupil is older than 59 months of age; and
(d) the prospective pupil must have received one dose of varicella vaccine, administered no earlier than 12 months of age.
(2) If a prospective pupil is not vaccinated with all of the vaccines required in (1), the prospective pupil may be admitted conditionally in accordance with the requirements of ARM 37.114.710.
(3) A preschool must keep immunization data for each enrolled pupil, including the date, month, and year of administration of all required vaccines. The HES 101 may be used for this purpose, but is not mandatory.
(4) If a religious or medical exemption is claimed, the preschool must maintain the record of that exemption in accord with the requirements of ARM 37.114.715 or 37.114.716, whichever applies.
