Streptococcus pneumoniae eta Haemophilus influenzae bakterio-espezieek eragindako infekzio inbaditzaile eta ez-inbaditzaileak: txertaketaren eraginak

Abstract

Infections caused by Streptococcus pneumoniae and Haemophilus influenzae are highly prevalent, with invasive infections causing severe cases. Vaccination is the main prevention strategy. Pneumococcal conjugate vaccines (PCV) and H. influenzae type b vaccine are included in the childhood vaccination schedule. Pneumococcal polysaccharide vaccine (PPSV23), on the other hand, is used in all adults over the age of 65 and is also recommended in other adults and children over 2 years of age who are more likely to develop a pneumococcal infection or develop serious complications.These vaccines have reduced the incidence and mortality of infections caused by these microorganisms, however, the burden of invasive disease is high. In addition, changes in serotype distribution and antimicrobial susceptibility profile have also been observed. It is important to maintain the use and coverage of these vaccines, but also do epidemiological surveillance about invasive pneumococcal disease (IPD) and invasive H. influenzae disesase. This way, it is possible to monitor epidemiological changes and ebaluate the development of furher prevention measures.
