Correct answer: B — Begin age-appropriate catch-up immunisation according to provincial schedule

When records are absent or unreliable, Canadian immunisation practice generally favours catch-up vaccination using provincial schedules rather than assuming protection. Serology may be useful for selected antigens but is not needed for every vaccine before starting. Measles vaccine alone is incomplete. Catch-up vaccination protects the child and school community.
