[Bacterial meningitis caused by Neisseria meningitidis. Prophylactic measures]
Abstract:
Meningitis caused by Neisseria meningitidis is one of the most frequent and most serious, with fatal rate between few up to 20%. Majority of cases are caused by Neisseria meningitidis of serological groups A, B, C, as well as Y and W 135. Vaccination is the most effective prophylactic measure against meningococcal meningitidis. Polysaccharide, not conjugated vaccines against Neisseria meningitidis serological groups A, C, W 135, Y effective for children over 2 years old, adolescents and adults as well as vaccine against serogroup C conjugated with protein carrier, effective for children over 2 months of life, adolescents and adults are used. Conjugated vaccine against serological group C was used in 1998/1999 in Great Britain in the mass vaccination of infants in 2, 3, 4 months of life, children and adolescents up to 17. In Poland as well as in other European countries serological group B is an etiological factor of majority of cases caused by Neisseria meningitidis. Intensive studies are performed in the field on effective, safety, cheap vaccine against all serological groups of Neisseria meningitidis.
Insights
Meningitis, a serious Neisseria meningitidis infection, has varying fatality rates. Vaccines exist for several serogroups, but research continues for a universal vaccine against all meningococcal groups.
Area of Science:
- * Infectious Diseases
- * Microbiology
- * Vaccinology
Background:
- * Meningitis caused by Neisseria meningitidis presents a significant public health challenge with fatality rates ranging from a few percent up to 20%.
- * The most common causative serogroups include A, B, C, Y, and W-135.
- * Vaccination is the primary strategy for preventing meningococcal meningitis.
Discussion:
- * Current vaccines include polysaccharide non-conjugated vaccines effective for specific serogroups (A, C, W-135, Y) in individuals over two years old, and a protein-conjugated vaccine for serogroup C effective from two months of age.
- * Mass vaccination campaigns utilizing the serogroup C conjugated vaccine have been implemented, such as in Great Britain in 1998/1999.
- * Serogroup B is a predominant cause of Neisseria meningitidis infections in Poland and other European countries.
Key Insights:
- * Existing vaccines target specific serogroups of Neisseria meningitidis, with varying age-appropriateness.
- * The prevalence of serogroup B necessitates ongoing research for broader protection.
- * Development of a universal vaccine against all serogroups remains a critical goal.
Outlook:
- * Continued research focuses on creating effective, safe, and affordable vaccines.
- * Advancements in vaccinology aim to provide comprehensive protection against all major meningococcal serogroups.
- * Future vaccines may offer broader coverage, potentially including serogroup B.
