For which age group is the haemophilus influenza type B vaccine recommended?

The Haemophilus influenzae type b (Hib) vaccine is primarily recommended for infants and young children to protect against serious bacterial infections, including meningitis, pneumonia, and epiglottitis caused by H. influenzae type b. The vaccination schedule typically begins at 2 months of age, with additional doses given at 4 months and 6 months, and then a booster can be given between 12 to 15 months of age.

The recommendation for the age group from 6 weeks to 19 years encompasses not only the very young population, who are at higher risk of severe disease, but also allows for continued vaccination for individuals who may not have completed their schedule during the recommended childhood years. While the specific focus is on infants and children under 5 years, extending the recommendation to 19 years ensures that those who may have missed their vaccinations still have access to this essential protection.

In contrast, the other age groups provided do not clearly reflect the recommended vaccination schedule as defined by health authorities. Options mentioning durations ending before 19 years either exclude necessary age ranges where vaccination is vital or do not encompass the complete recommended duration for completing the Hib series.
