Coverage of and barriers to varicella vaccination in children at Fundación Salud Bosque
Abstract
Introduction. Ever since the introduction of the varicella vaccine in Colombia, coverage has not surpassed 90%. The objective of this work is to identify the barriers to varicella vaccination in children. Methodology. A descriptive study conducted at Fundación Salud Bosque. 27 patients were studied - 18 males (67%) and 9 females (33%) - including children under 18 years of age with varicella, and excluding patients with blistering diseases other than varicella and burns. A demographic characterization was conducted. Averages and standard deviations were used for quantitative variables, and the proportion ratio was used for qualitative variables with Stata V12®. Results. The incidence of varicella was 0.2%. Only 9 patients (33%) had received the first dose of the vaccine, and none had received the second dose. 92.5% required sick leave, 89% required painkillers, 63% required antihistamines, and 26% required antibiotics. Discussion. The conducted study shows a significantly lower incidence compared to other international cohorts. Colombia has not achieved the varicella vaccination coverage of Uruguay, Costa Rica, the United States, Australia, Europe and Taiwan due to the barriers to applying it. Meanwhile, the varicella vaccine has not been introduced in Africa because there are other priorities, such as malnutrition, malaria and the Human Immunodeficiency Virus infection. Conclusions. Vaccination coverage has not been achieved because of modifiable barriers that increase the incidence and burden of the disease due to costs of sick leave, pharmacological treatment and school absenteeism.
