Which vaccine is routinely administered to infants to prevent bacterial meningitis caused by Hib?

The vaccine routinely administered to infants to prevent bacterial meningitis caused by Haemophilus influenzae type b (Hib) is specifically the Hib vaccine. This vaccine is crucial because Hib can lead to serious infections, including bacterial meningitis, pneumonia, and epiglottitis, particularly in children under five years of age.

The Hib vaccine is typically given as part of a combination vaccine schedule during infancy, starting at 2 months of age. It effectively stimulates the immune system to recognize and fight off the bacteria, thereby reducing the risk of these severe diseases.

While other vaccines listed play important roles in preventing various infections, they do not specifically target Hib-related diseases. The MCV4 vaccine is aimed at preventing meningococcal disease, the DTP vaccine protects against diphtheria, tetanus, and pertussis, and the PCV13 vaccine is focused on pneumococcal diseases. Thus, for the specific prevention of bacterial meningitis caused by Hib, the Hib vaccine is the appropriate choice.
