Hib vaccine

The Hib vaccine protects against Haemophilus influenzae type b bacteria, which can cause serious infections like meningitis, pneumonia, and blood infections, especially in young children. The vaccine is usually given in several doses starting at a few months old. It works by teaching the immune system to recognize and fight the bacteria if exposed, preventing illness. The Hib vaccine is highly effective and has significantly reduced cases of Hib-related diseases worldwide, making it a crucial part of childhood immunization programs.
