Estudio sobre la pauta vacunal infantil de meningitis B en Zaragoza

Abstract

BackgroundMeningococcal disease caused by Neisseria Meningitidis is a life-threatening disease, with the highest incidence rates in children under 5 years of age. Since 2015, a vaccine against serogroup B, the most prevalent in Europe, has been available in Spain. The objective of the study was to analyze the vaccination of children with Meningitis B in Zaragoza. MethodsA descriptive observational study was carried out with 11776 of 13 Health Centers of Sector I of Zaragoza, aged 0 months to 15 years, with a history of Meningitis B vaccination between January 2015 and December 2019. It was determined sex, date of birth, date and age of primary vaccination, health center and vaccination schedule. A descriptive analysis and hypothesis testing was carried out to analyze the results. Results50.4% of those vaccinated were between 2 and 9 years old. In 2016, children under 3 months of age represented 7.2% of the total vaccinated, increasing in 2019 to 50.9%. 83.8% of the children were well vaccinated, with a mean age of 5.5 years. Interval errors were more common in the 12-23-month group (55.9%). There were no differences between both sexes in relation to the pattern received. ConclusionsThe percentage of well vaccinated is high. The percentage of interval errors in the 12 to 23 month group, with a more complex vaccination schedule, is of concern. It is important to minimize errors in vaccination to achieve better protection rates.
