This vaccine is given as a single booster shot for children ages 15 months through four years old. Hiberix is typically injected into the upper arm or thigh muscle.
Ideally, children will have fully completed their Hib immunizations before 15 months of age and will not need Hiberix. However, there was a shortage of Hib vaccines for a few years, and the booster dose of Hib vaccine was temporarily suspended; the shortage has now been largely resolved, and the booster has been reinstated. As a result, there are now many children older than 15 months old who need a booster dose.
