New vaccine administration practice recommendations from the Canadian Immunization Guide

Abstract

Background: The Canadian Immunization Guide (CIG) is published online by the Public Health Agency of Canada and summarizes guidance on vaccines for human use into a single resource. Chapters are reviewed and updated on a regular basis. Vaccine administration is a critical part of any immunization program. Recently, the CIG chapter on vaccine administration practices was updated.; Objective: To provide highlights of recent changes to the Vaccine Administration Practices chapter of the CIG.; Approach: Vaccine-specific guidance in the CIG is based on National Committee on Immunization (NACI) and Committee to Advise on Tropical Medicine and Travel (CATMAT) recommendations as well as new recommendations developed by the CIG Working Group members and NACI Secretariat technical staff. New recommendations are based on a review of the literature, including systematic reviews when available, a review of guidance provided by other National Immunization Technical Advisory Groups and expert opinion. The revisions are approved by the Working Group chair, as well as NACI.; Results: Highlights of new recommendations include the following: vaccine providers should adhere to jurisdictional or organizational policies and procedures regarding combining the contents of multi-dose vials; clinical judgement should be used when selecting needle length for intramuscular injections that takes into account the vaccine recipient's weight, gender and age; filter needles are not recommended for vaccine administration as they may filter out active ingredients such as adjuvants; an injection site other than in an area where lymphatic drainage may be impaired should be considered; there is no evidence or theoretical rationale for avoiding injection through a tattoo or superficial birthmark; and immunization pain management strategies have now been developed for all ages.; Conclusion: Recommendations in vaccine administration practices have recently been changed in some important ways. The Public Health Agency of Canada is committed to providing information on immunization in an easily accessible, reader-friendly format for healthcare providers and policy-makers.
