Introduction: To describe clinical features, complications, serotypes and antibiotic resistance in pneumococcal pneumonia in our environment after the generalization of the heptavalent conjugate vaccine (PCV-7) in paediatrics. Material and methods: Prospective study of episodes of pneumococcal pneumonia, with positive cultures in patients treated in the emergency department from January 2006 to February 2010. Results: We studied 346 episodes in 320 patients, 335 belonged to 309 adult patients, 221 (71.5%) males, median age 68 years (range 16-94), and 11 episodes to patients < 15 years. Two-hundred and thirty seven (68.5%) episodes were community acquired. Bacteraemia was present in 130 (37.6%) cases, with a tendency towards an increased risk in patients < 65 years (OR = 1.56, 95% CI 0.96- 2.56, P = .07). Thirteen
