HIB (Haemophilus Influenza type B vaccine): This immunization prevents invasive infections due to Haemophilus Influenza type B bacteria. The most serious of these is meningitis, but also includes buccal cellulitis, pneumonia, ear infections and sepsis (blood infection). This vaccine will not protect your child against all forms of meningitis, but will prevent this form of meningitis. Side effects of the HIB vaccine are very uncommon. This vaccine has virtually eliminated the most common form of meningitis that we as pediatricians previously routinely treated just 20 years ago. This vaccine has been a medical miracle for young children, with the virtual eradication of the leading cause of meningitis in young children.
