Point de pratique de la SCP : Les avantages d’administrer le vaccin antigrippal pendant la grossesse pour le fœtus et le nourrisson de moins de six mois

La grippe est un grave problème pour les nourrissons de moins de six mois. Chez ces nourrissons, le taux d’hospitalisation attribuable à cette maladie et à des maladies connexes est comparable à celui des personnes âgées. Puisque les vaccins antigrippaux ne sont pas efficaces dans ce groupe d’âge, la stratégie optimale, fondée sur des données probantes, consiste à administrer les vaccins trivalents inactivés pendant la grossesse. L’administration de ces vaccins au cours des deuxième et troisième trimestres a fait l’objet d’études approfondies et est sécuritaire. Non seulement protège-t-elle la femme enceinte et son nourrisson de moins de six mois, mais elle est également bénéfique pour le fœtus. En effet, ce vaccin contribue à réduire le risque de faible poids à la naissance.

Repeated annual influenza vaccination and vaccine effectiveness: review of evidence

Substantial heterogeneity in repeated vaccination effects is not surprising given the variation in study populations and seasons, and the variable effects of antigenic distance and immunological landscape in different age groups and populations. Caution is required in the interpretation of pooled results across multiple seasons, since this can mask important variation in repeat vaccination effects between seasons. Multi-season clinical studies are needed to understand repeat vaccination effects and guide recommendations.

Stratégie canadienne de vaccination en cas de pandémie

Esquisse la stratégie canadienne de vaccination en cas de pandémie telle qu’elle est décrite dans l’annexe du document Préparation du Canada en cas de grippe pandémique portant sur les vaccins. La stratégie englobe l’ensemble des éléments constitutifs d’un programme de vaccination, notamment l’établissement de priorités pour la distribution initiale de vaccins, la sécurisation de l’approvisionnement en vaccins antipandémiques, l’innocuité des vaccins, la distribution et l’entreposage des vaccins, l’attribution et le niveau d’utilisation des vaccins.

The impact of repeated vaccination on influenza vaccine effectiveness: a systematic review and meta-analysis

From the patient perspective, the study’s results support current season vaccination regardless of prior season vaccination. Researchers found no overall evidence that prior season vaccination negatively impacts current season vaccine effectiveness. It is important that future vaccine effectiveness studies include vaccination history over multiple seasons in order to evaluate repeated vaccination in more detail.

The Importance of Frailty in the Assessment of Influenza Vaccine Effectiveness Against Influenza-Related Hospitalization in Elderly People

Influenza is an important cause of morbidity and mortality among older adults. Even so, effectiveness of influenza vaccine for older adults has been reported to be lower than for younger adults, and the impact of frailty on vaccine effectiveness and outcomes is uncertain. Researchers aimed to study vaccine effectiveness against influenza hospitalization in older adults, focusing on the impact of frailty.

Assessing vaccine safety within Ontario's Universal Influenza Immunization Program, 2012-2013 to 2014-2015

Objective: To summarize adverse events following immunization (AEFIs) reported after receipt of influenza vaccines administered within the Universal Influenza Immunization Program in Ontario.

Conclusion: This assessment found a low rate of reported adverse events following influenza vaccines administered in Ontario. Most reported events were mild and resolved completely. The findings were consistent with the very good safety profile of influenza vaccines.
