Invasive pneumococcal disease (IPD) is a main cause of mortality associated with pneumococcal infections. Although, IPD is regarding mainly small children and persons in the age > 65 years, the investigations showed that because of IPD exactly sick persons are burdened with the greatest mortality in the older age, rather than of children. The most frequent form of IPD is community acquired pneumonia (CAP) with the bacteremia. The presence of even a single additional risk factor is increasing the probability of the unfavorable descent of pneumococcal infection. The risk factors for IPD and/or pneumonia with bacteremia apart from the age are among others asthma (> 2 x), chronic obstructive pulmonary disease (COPD), sarcoidosis (4 x), idiopathic pulmonary fibrosis (5 x), bronchiectases (2 x), allergic alveolitis (1.9 x) and pneumoconiosis (2 x), type 1 diabetes (4.4 x), type 2 diabetes (1.2 x), autoimmune diseases (e.g. rheumatoid arthritis (4.2 to 14.9 x), kidney failure with the necessity to dialysis (12 x), immunosuppression, cardiovascular disease, alcoholism and cancers. Examinations show that the best method of IPD and CAP preventing are pneumococcal vaccinations. On the market for ages 23-valent polysaccharide vaccine (PPV23) is available covering close the 90% of IPD triggering stereotypes. Her role in preventing CAP is uncertain and the immunological answer after vaccination at older persons and after revaccination is weak. Widely discussed disadvantageous effects of growing old of the immunological system show on the benefit from applying the immunization inducing the immunological memory, i.e. of conjugated vaccines which are activating the T-dependent reply and are ensuring the readiness for the effective secondary response. Examinations so far conducted with conjugated 7-valent and 13-valent (PCV13) vaccines at persons in the age > 50 years are confirming these expectations. Also sick persons can take benefits from PCV13 applying back from so-called IPD risk groups in the age > 19 years. At these work research findings were described above PPV23 and PCV13 at adults and world recommendations of applying both vaccines in risk groups from 19 years up to the advanced years. Also Polish recommendations of optimum applying of these vaccines were presented. They are recommending applying PCV13 at first in them, while PPV23, if to her readings exist should be given to > or = 8 of weeks from PCV13. In persons > or = 19 years which earlier received 1 or should receive more PPV23 doses first PCV13 dose should be given after the year or later than the last PPV23 dose, and then again PPV23 > or = 8 of weeks from PCV13 and the second PPV23 dose not earlier than 5 years from last PPV23. If the PPV23 application seems to be justified, it is irrespective of the more previous state vaccination against pneumococci, PCV13 should be given to as first.
