Ideally, the vaccination should be given 4 weeks before travel. A combined hepatitis A and hepatitis B vaccine is also available in Australia. It is given as a course of 3 doses of vaccine: one vaccination is given immediately, the second is given one month later, and the third is given 5 months after that.
Although Haemophilus influenzae is not the cause of influenza, it is still responsible for a number of different clinical diseases in humans. And since it is able to adapt to the penicillin binding protein, it has acquired a level of resistance to the different kinds of penicillin antibiotics. Haemophilus influenzae is a non-motile, Gram-negative, fastidious, non-spore forming, facultative anaerobic, rod-shaped bacterium.
Haemophilus influenzae can cause infections in children and sometimes in adults who have a chronic lung disorder or a weakened immune system. Infection is spread by sneezing, coughing, or touching infected people. One type of Haemophilus influenzae, called type b, is more likely to cause serious infections. In children, Haemophilus influenzae type b (Hib) can spread through the bloodstream (causing bacteremia) and infect the joints, bones, lungs, skin of the face and neck, eyes, urinary tract, and other organs.
