What is the recommended number of doses for the Haemophilus influenzae type B vaccine, PedvaxHIB?

The recommended number of doses for the Haemophilus influenzae type B (Hib) vaccine, specifically PedvaxHIB, is three doses. This vaccination schedule typically includes doses given at 2 months, 4 months, and a booster dose at 12 to 15 months of age.

Vaccination helps protect against serious diseases caused by Hib, such as meningitis and pneumonia, particularly in young children who are more vulnerable to these infections. Adhering to the recommended schedule ensures adequate immunity is developed at the right time during a child's early years, aligning with public health guidelines aimed at preventing outbreaks and protecting community health.

Other choices reflect either an insufficient number of doses, which would not provide optimal immunity, or an excessive count that can lead to unnecessary complications without added benefits. Thus, three doses is the appropriate regimen for achieving the desired protection.
