Which statement best describes the initial meningococcal vaccination schedule?

• A. One dose, or more if needed every 5 years
• B. Two doses, with boosters every 3 years
• C. Three doses total in a lifetime
• D. One dose only with no boosters

Answer: (A)

Meningococcal protection starts with an initial dose, but immunity can wane over time, especially for people who remain at ongoing risk. Because of that, a booster is given if continued protection is needed. A booster about every 5 years is the standard approach for individuals who still face risk (such as certain medical conditions or exposure scenarios). The other options imply either rotating through multiple doses in shorter intervals or no boosters at all, which doesn’t align with how protection is maintained for those at ongoing risk. So the best description is an initial dose, with boosters every 5 years if needed.
