The aim of this study was to assess long-term effects of pneumococcal vaccination with 23-valent polysaccharide vaccine (PPV23) and 13-valent conjugate vaccine (PCV13) in patients with bronchial asthma. Methods. One hundred and three patients with mild to severe asthma were involved. They were randomly assigned to vaccination with PCV13, or PPV23, or PPV23 followed by PCV13, or vice versa. Clinical efficacy of vaccination was evaluated using number of asthma exacerbation a year before and 1 and 4 years after the vaccination; need in antibiotics a year before and 1 and 4 years after the vaccination; and number of hospitalizations due to asthma exacerbation a year before and 1 and 4 years after the vaccination. Results. In a year after vaccination, number of patients who had not experienced asthma exacerbation increased significantly in PPV23, PPV23/PCV13, and PCV13/PPV23 groups (p < 0.01 to p < 0.001). In 4 years after vaccination, number of patients without exacerbations increased significantly in PCV13/PPV23 group only (48.1%; p < 0.01). Number of patients who did not require hospitalization due to asthma exacerbation increased significantly in PCV13 group only (81.8%; p < 0.05). Conclusion. The authors proposed a hypothesis of impact of pneumococcal vaccines on immunopathogenesis of bronchial asthma. The authors consider vaccination against pneumococcus using PCV13 followed by PPV23 should be a part of the basic therapy of asthma.
