|Title:||Adverse Events After Pneumococcal Vaccination [eventos Adversos Após Vacinação Contra O Pneumococo]|
|Abstract:||Objective: To study the occurrence of adverse events after administration of a capsular polysaccharide vaccine against 23 pneumococcal serotypes in individuals for whom such vaccination is indicated. Methods: This was a prospective study, conducted in a general hospital in the city of Sumaré, Brazil, in which 152 individuals were evaluated after intramuscular vaccination with 0.5 mL of the Pneumo 23® vaccine. The study variable was subject complaint of at least one symptom forming a temporal nexus with the vaccine (appearing within 48 h after its administration). The subjects were evaluated at five to seven days after vaccination. The covariables age, gender and clinical profile were tested using the chi-square test and multiple logistic regression, with the level of significance set at 5%. Results: The age of the population ranged from 5 to 86 years (mean, 61.8 years). For nearly all (99%) of the subjects, the vaccination evaluated was their first dose of the vaccine. Events occurring at the injection site were reported in 36 subjects (23.7%). Of those 36 events, 24 (68%) were mild and had no repercussions for the daily activities of the subjects. Pain at the site of the injection was the most common symptom, being reported by 97.2% of the subjects. Erythema and localized edema were found in 6.3% and 5.1% of the subjects, respectively. Of the subjects evaluated, 12.8% reported general symptoms (malaise, fever, sleepiness and generalized pain). In the bivariate analysis, none of the covariables were found to present a statistically significant correlation with adverse events (p > 0.20). The same held true in the multivariate analysis. Conclusion: Although, the 23-valent pneumococcal vaccine provokes few reactions in the first dose, it is still rarely recommended in the region, even for patients at risk.|
