Haemophilus influenzae can cause pneumonia, but it is not what causes influenza. Influenza is a disease that is caused by a virus. Haemophilus influenzae is the name of a bacterium. It was originally thought to be the cause of influenza before they had discovered viruses, that is how a bacterium got the name with "influenzae" in it. This type of bacteria also can cause meningitis, septic Arthritis, and many other infections, commonly in children under 5 who have immature immune systems. It is a bacterium that can be present without causing illness, unless the person has a suppressed immune system.
