They show the efficacy of the meningitis B vaccine in children under five years of age – Society

The vaccine against meningitis B used in Spain is effective in children under five years of age, according to a study that indicates that children who have received it have a 71% lower risk of contracting the disease.

Led by Jesús Castilla Catalán, from the Institute of Public and Labor Health of Navarra, the research indicates that the 4CMenB vaccine, which is marketed as Bexsero, also protects against serogroups other than B.

Serogroup B meningococcus is the leading cause of invasive meningococcal disease in Spain, the most frequent presentations of which are meningitis and sepsis.

The observational study published by the New England Journal of Medicine was carried out throughout Spain with data, between October 2015 and September 2016, of 1,530 minors between two months and five years of age.

Among them, there were 306 confirmed cases of invasive meningococcal disease in that period in Spain and the rest belonged to various control groups, Castilla Catalán told Efe.

The serogroup B meningococcal vaccine was approved with immunogenicity studies -it happens with rare diseases- and it began to be used in Spain in children in 2014.
