Which statement about meningococcal vaccination is correct?

Which statement about meningococcal vaccination is correct?

• A. A booster provides lifetime protection after a single dose
• B. A booster may be needed every 5 years
• C. Booster every 10 years
• D. Booster is never needed

Answer: (B)

Protection from meningococcal vaccines can wane over time, so maintaining protection for people with ongoing risk often requires a booster. In certain high-risk groups—such as individuals with an absent or impaired spleen or complement deficiencies, or those with prolonged exposure during outbreaks—a booster at intervals like five years helps keep immunity up to date. A single dose does not guarantee lifelong protection, and while routine schedules include initial doses and specific booster timings, they don’t universally provide lifetime protection from one shot. The idea that a booster is never needed isn’t correct for those with persistent risk. So the statement that a booster may be needed every five years best reflects how boosters are used to maintain protection in people at ongoing risk.
