Since the booster dose of Hib vaccine can be given at 12-15 months, is it still necessary to “boost” two months later if the first dose was given at 12-14 months?
If the child received a primary series (2 or 3 doses) of Hib vaccine in the first year of life, then the final (booster) dose of the series may be given as early as 12 months, provided at least 2 months have passed since the last dose. An unvaccinated 12-14 month old child should receive one dose as a primary series, and a booster dose 2 months later. Unvaccinated children 15-59 months of age need only a single dose of any licensed conjugate Hib vaccine.

- If a child received two doses of Hib vaccine and the second dose was given at 13 months of age, does the child need a third dose?
- If a dose of Hib vaccine was given by mistake to a 2-week-old, should further doses of Hib vaccine be given?
