Streptococcus pneumoniae is an infectious bacterium that has killed millions of people around the world. Pneumococcal diseases are the illnesses produced by this bacterium. This pathogen colonises its host's nasopharynx asymptomatically, but can eventually spread to sterile tissues and organs, causing infections. Pneumonia is the most frequent pneumococcal infection nowadays. Pneumococcal pneumonia is a global health hazard that disproportionately affects children under the age of five, the elderly, and people with pre-existing medical conditions. S. pneumoniae possesses a wide range of virulence characteristics that help it stick to host tissues, invade them, and evade host immune responses. A greater understanding of S. pneumonia’s virulence factors, host immune responses, and current approaches for diagnosis, treatment, and disease prevention would allow the pathogen and associated diseases to be better regulated. Other factors to consider in disease prevention are the influence of age on vaccine responses and vaccine efficacy.
