At what age is a booster dose for Hib recommended?

The correct recommendation for a booster dose of the Haemophilus influenzae type b (Hib) vaccine is at 12-15 months of age. The primary series of the Hib vaccine consists of multiple doses, usually given at 2, 4, and 6 months of age. The booster dose is crucial for ensuring continued immunity as the child ages, particularly because the risk of Hib disease increases as children get older, especially in those who may not have received the full primary vaccination series.

Immunological responses can wane over time, which is why a booster is beneficial at this specific age. The timing aligns with standard pediatric vaccination schedules, supporting the development of adequate immune memory against Hib.

While it's important to stay on track with the vaccination schedule for children, focusing on the booster dose at the 12-15 month mark ensures that children are adequately protected as they transition from infancy into toddlerhood, when they may be more exposed to common pathogens.
