Long-term serological response and boostability of intradermal rabies immunization: A retrospective chart review.

Objectives: Rabies vaccines in Canada are currently labeled for intramuscular use only; however, intradermal vaccine administration may be equally effective. This study aims to assess the immediate and long-term (≥ 2 years) serological response and boostability of intradermal administration of rabies vaccine for pre-exposure prophylaxis.

Methods: This retrospective cohort study was conducted using data from electronic medical records at the Winnipeg Regional Health Authority Travel Health & Tropical Medicine Services Clinic.
