[Evaluation of the change in pneumococcal vaccination in 2018 in adults in the Community of Madrid]

Abstract

Background: In the Community of Madrid since 2005 vaccination against pneumococcus in adults from 60 years of age has been carried out with pneumococcal polysaccharide vaccine (PPV23). In January 2018, the guideline changed in favor of pneumococcal conjugate vaccine (PCV13). The objective of this study was to analyze the data of pneumococcal vaccination and to evaluate the implementation of the new guideline of vaccination against pneumococcus in adults in the Community of Madrid.

Methods: Cross-sectional study to estimate vaccine coverage by a retrospective review of the record of vaccination history of people ≥60 years resident in the Community of Madrid.

Results: In the Community of Madrid until 2018, 83% of the population were vaccinated with PPV23, 6% with PCV13 and 11% with both vaccines. 96.5% came from Primary Care records. The doses administered of PCV13 surpassed those of PPV23 in ≥60 years in all age groups. 78,660 people ≥60 years were vaccinated with PCV13 (19.5% without risk factors, 67.3% with chronic diseases, 2.5% of the high-risk group and 10.7% belonging to both groups).

Conclusions: In 2018, following Community of Madrid recommendations, 6,639 people were not properly vaccinated with PCV13 and 72,021 (91.6%) were properly vaccinated. The greatest confusion occurred in people ≥60 years without risk factors who had a previous PPV23 and did not require another vaccine but received a PCV13 without complying with the recommended schedule.
