Meningococcal conjugate vaccines policy update: booster dose recommendations
Insights
Updated guidelines recommend routine quadrivalent meningococcal conjugate vaccine for adolescents at ages 11-12 and 16. High-risk individuals require specific dosing schedules for meningococcal disease prevention.
Area of Science:
- Public Health
- Vaccinology
- Epidemiology
Background:
- Updated recommendations for quadrivalent meningococcal conjugate vaccines (Menactra, Menveo) have been approved by the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics.
- These guidelines supplement existing recommendations for meningococcal vaccinations in adolescents and high-risk populations.
Purpose of the Study:
- To review data on immunogenicity, antibody persistence, disease epidemiology, vaccine effectiveness, and cost-effectiveness for meningococcal conjugate vaccines.
- To establish updated vaccination schedules for adolescents and individuals at persistent high risk of meningococcal disease.
Main Methods:
- Review of scientific data including immunogenicity studies in high-risk groups.
- Analysis of bactericidal antibody persistence post-immunization.
- Evaluation of current meningococcal disease epidemiology and vaccine effectiveness data.
- Assessment of cost-effectiveness for various adolescent vaccination strategies.
Main Results:
- Routine immunization for adolescents is recommended at 11-12 years of age with a booster at 16 years.
- Specific schedules are provided for adolescents receiving their first dose at different ages (13-15 years, or 16+ years).
- A 2-dose primary series is recommended for individuals with complement deficiencies, asplenia, or HIV infection, with specific booster intervals.
Conclusions:
- The updated recommendations aim to optimize protection against meningococcal disease in key populations.
- Adherence to these schedules is crucial for preventing invasive meningococcal disease, particularly serogroups A, C, Y, and W-135.
- The guidelines emphasize tailored vaccination strategies based on age and risk factors for meningococcal disease.
Abstract:
The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the American Academy of Pediatrics approved updated recommendations for the use of quadravalent (serogroups A, C, W-135, and Y) meningococcal conjugate vaccines (Menactra [Sanofi Pasteur, Swiftwater, PA] and Menveo [Novartis, Basel, Switzerland]) in adolescents and in people at persistent high risk of meningococcal disease. The recommendations supplement previous Advisory Committee on Immunization Practices and American Academy of Pediatrics recommendations for meningococcal vaccinations. Data were reviewed pertaining to immunogenicity in high-risk groups, bactericidal antibody persistence after immunization, current epidemiology of meningococcal disease, meningococcal conjugate vaccine effectiveness, and cost-effectiveness of different strategies for vaccination of adolescents. This review prompted the following recommendations: (1) adolescents should be routinely immunized at 11 through 12 years of age and given a booster dose at 16 years of age; (2) adolescents who received their first dose at age 13 through 15 years should receive a booster at age 16 through 18 years or up to 5 years after their first dose; (3) adolescents who receive their first dose of meningococcal conjugate vaccine at or after 16 years of age do not need a booster dose; (4) a 2-dose primary series should be administered 2 months apart for those who are at increased risk of invasive meningococcal disease because of persistent complement component (eg, C5-C9, properdin, factor H, or factor D) deficiency (9 months through 54 years of age) or functional or anatomic asplenia (2-54 years of age) and for adolescents with HIV infection; and (5) a booster dose should be given 3 years after the primary series if the primary 2-dose series was given from 2 through 6 years of age and every 5 years for persons whose 2-dose primary series or booster dose was given at 7 years of age or older who are at risk of invasive meningococcal disease because of persistent component (eg, C5-C9, properdin, factor H, or factor D) deficiency or functional or anatomic asplenia.
