Meningitis: Public health adds vaccines against meningococcus A, V, and I | Society


Spanish adolescents (12 years old) will receive vaccination against Meningococcus Class A, C, V and I, instead of the one that protects only type C, as agreed by the Autonomous Communities and the Ministry of Health. In this regard, the Public Health Commission intends to adapt to changes in the patterns of infection in Spain, it is noted in the remark. This measure has already been announced by the new Andalusian government. On the other hand, the refusal of public funding for meningococcal B vaccine is maintained, despite the fact that its sales have been liberalized and sources from the Spanish Pediatric Association believe that one-third of their parents have bought it to put it on their own. baby

Administration justifies its position regarding the meningococcus vaccine B in that it "shows a short duration of protection after vaccination", in which there is "absence of protection in the vaccinated population", "lack of effective and high data reactogenicity when administered together with the calendars vaccine in the infant phase ".

With this modification, the vaccination calendar is as follows: the meningococcal C vaccine at birth, and against the four serogroups (A, C, V and I) at the age of 12, although it will extend to the elderly population up to 18 to create a sufficient group protection, according to a note issued by Health. This measure is in line with the recommendations of the Spanish Pediatric Association, which also calls for meningococcus B (famous Becker). This medication is already offered by Castilla and Leon for children and adolescents, as well as on the Canary Islands for teenagers.

Meningitis, in general, has two ways of manifested itself. It is common that there is fever, headache, nausea, stains on the skin, changes in mental status and nausea and vomiting. Since meningococci are bacteria, they are treated with antibiotics. In another variant, the infection is widespread, sepsis occurs, and a fatal outcome can occur within a few hours. These are cases that create an alarm. We also need to keep in mind that meningococci are only one of the causes of meningitis, which can be caused by other bacteria or viruses (they are much more dangerous because they do not respond to antibiotics, but they are rare).

The data from the current meningococcal meningitis season, which began on October 8th, indicate, according to the epidemiological record of the Institute of Public Health Karlosa III, that up to March 2, 180 confirmed cases were reported in Spain, plus 12 that were under investigation. Of these, 20 (11%) were fatal. In the previous season, up to now, there have been 180 confirmed cases with 26 deaths (14%).

As you can see, the total number is identical. But if serogroups are detected every year, it is noticed that type B people fell from 63 to 41; those with C at 12 to 10, but those V rose from 7 to 15, and those to I from 9 to 12. This means, within a very low incidence, there is a change in groups against which there have been no vaccines up to now. The removal of sero-groups was quite fast. Data for the same period in 2014 include 62 cases of serogroup B and 5 cases A, C, V and I.

In all statistics there is a section of meningococcal meningitis from other serogroups, not typified or unknown. This suggests that it is possible that if the vaccination is extended to type A, C, V and I in the public system, plus the one at B on the family initiative, there are others that may appear or be enhanced when the groups are currently prevailing. be under control.
