Abstract

SILVA, Tomás et al. Pneumococcal vaccination in adults with invasive pneumococcal disease: an overview in a Portuguese community. Rev Port Med Geral Fam [online]. 2020, vol.36, n.4, pp.335-340. ISSN 2182-5173.  https://doi.org/10.32385/rpmgf.v36i4.12676.

Objectives: To describe all cases of invasive pneumococcal disease reported in adult residents of Matosinhos between 2016 and 2018 while assessing their vaccination status and compliance with clinical guideline no. 011/2015, which establishes the risk groups to whom pneumococcal vaccination of adults is recommended in Portugal. Methods: Retrospective analysis of the confirmed cases of invasive pneumococcal disease in adults (aged ≥ 18 years) residing in the municipality of Matosinhos, notified through the Sistema Nacional de Vigilância Epidemiológica (SINAVE) between 2016 and 2018. Descriptive analysis of the cases and evaluation of the vaccination status according to the clinical guideline no. 011/2015. Results: There were 47 confirmed cases, 66.0% in patients aged 65 years and older, and 83.0% aged 50 years or older. In all cases, 37 (78.7%) had at least one of the risk conditions for the disease listed in the guideline. Of these, five (13.5%) had pneumococcal vaccination records, and one (2.7%) had the complete recommended regimen. Conclusions: A reduced proportion of invasive pneumococcal disease cases was previously vaccinated. Several reasons may justify the results found and more research is needed. We emphasize the importance of age as a risk factor, justifying the evaluation of its inclusion in the recommendations. This study highlights the importance of invasive pneumococcal disease, as well as the need to evaluate the compliance with Portuguese guideline no. 011/2015, to promote pneumococcal vaccination among both health professionals and the general population and the need to re-evaluate the current recommendations.
