[Impact of vaccination with pneumococcal vaccines on recurrent pneumonia in patients with chronic obstructive pulmonary disease].

A retrospective analysis showed that, firstly, CAP is a fairly frequent complication of COPD: initially, the average percentage of cases of САР was 19.3%. Secondly, the risk of developing repeated episodes of pneumonia remains quite high in unvaccinated patients and tends to increase within 5 years: from 17 to 22%. Thirdly, the pneumococcal vaccines used have different effects on the risk of recurrent pneumonia in patients with COPD, a significant decrease in the number of recurrent pneumonia is observed only with the use of conjugated vaccines.
