[Efficacy and safety of pediatric flu vaccination: a systematic review].

Abstract

Objective: Children are at a higher risk of influenza infection compared to the general population. The World Organization Health and recommendations of the Vaccine Advisory Committee of the Spanish Association of Pediatrics contemplate annual vaccination as the most effective way to prevent the disease. Therefore, the purpose of this review was to update information on efficacy and safety in the anti -shed vaccine in children and adolescents.

Methods: A search in four electronic databases (Scopus, Cumulative Index to Nursing and Allied Health Literature, Medline / Pubmed, Google Scholar and Cochrane), as well as a manual search to identify original research published between 2012 and 2022. The guidelines of ANALYSIS (PRISMACR) as a preferred report element for systematic reviews.

Results: Seven original research articles were included where two issues of antigripal vaccination were identified in healthy children/adolescents and with pathologies. The efficacy (between approximately 30% and 80%) varied depending on the vaccine used and circulating subtypes. Most adverse reactions were mild intensity, and the most common local adverse event was pain in the injection site.

Conclusions: We positively highlight the safety of pediatric flu vaccination in analyzed studies, on the contrary, with respect to the efficacy of flu vaccination, we observe a wide variability of results. There is a clear need to continue conducting efficacy and safety studies in the child.
