Haemophilus influenzae, all types
Haemophilus influenzae is a bacteria that has six strains (types “a” through “f”), as well as strains that cannot be typed; type b (Hib) is the most serious. Hib is spread through contact with respiratory droplets and nasal or throat discharges. Hib can cause meningitis and other serious infections, particularly in young children. In Ontario, a vaccine series to prevent Hib disease is given to infants and toddlers and the disease is now uncommon.
To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
