Haw. Rev. Stat. § 325-34
Section 325 -32 shall be construed not to require the vaccination or immunization of any person for three months after a duly licensed physician, physician assistant, advanced practice registered nurse, or an authorized representative of the department of health has signed two copies of a certificate stating the name and address of the person and that because of a stated cause the health of the person would be endangered by the vaccination or immunization, and has forwarded the original copy of the certificate to the person or, if the person is a minor or under guardianship, to the person's parent or guardian, and has forwarded the duplicate copy of the certificate to the department for its files.
No person shall be subjected to vaccination, revaccination or immunization, who shall in writing object thereto on the grounds that the requirements are not in accordance with the religious tenets of an established church of which the person is a member or adherent, or, if the person is a minor or under guardianship, whose parent or guardian shall in writing object thereto on such grounds, but no objection shall be recognized when, in the opinion of the director of health, there is danger of an epidemic from any communicable disease.
