Four years ago, the district said No to the HPV vaccine, a position that was strongly supported by Calgary Bishop Fred Henry, who opposed the vaccine on moral and religious grounds.
The district's board of trustees now says because of recent medical studies it will consult with parents about offering the vaccine to Grade 5 girls.
The Calgary Catholic district is the only school board in a major Canadian city that doesn't allow students to receive the HPV vaccination at school.
Earlier this month, researchers published a study in the journal Pediatrics that says the HPV vaccine has not been linked to increased sexual activity in girls.
A group called HPV Calgary said last month it may launch a legal challenge against the school district over its anti-vaccine policy.
