Head Start on Vaccinations Act

Amends the Head Start Act to prohibit the enrollment of a child in a Head Start or Early Head Start program unless the child's parent or guardian: (1) provides the program with information establishing that the child is vaccinated in accordance with the pediatric vaccine list; or (2) submits a signed agreement to provide such information and consents to the provision, by a program employee or other health care provider, of any vaccines on the pediatric vaccine list that the child has not yet received. Requires that information to be provided on an annual basis in order for a child to maintain enrollment in such program.

Requires any child who is not in compliance with such requirements to be removed from such program, but provides for the exemption of children for whom the administration of such vaccines is medically contraindicated.

Authorizes the director of a Head Start or Early Head Start agency to use program funds to: (1) administer the required vaccines to children, at the request of the parent or guardian; or (2) assist the parent or guardian in gaining access to the required vaccines.
