The name coupon arose because in the past, paper bond certificates were issued which had coupons attached to them, one for each interest payment. On the due dates the bondholder would hand in the coupon to a bank in exchange for the interest payment.
Hib vaccine. Haemophilus influenzae type B vaccine is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%. It has therefore resulted in a decrease in the rate of meningitis, pneumonia, and epiglottitis.
Immunisation has dramatically reduced cases of Hib meningitis, but in countries which have not introduced the vaccine, Hib is still a major cause of serious disease in children. References. 1  JCVI Statement: Haemophilus influenzae type b (Hib) Disease and Hib Vaccine. Although the risk of getting Group C meningococcal disease is not high, it outweighs any small risk from the vaccine. 2  The vaccine is not 'live' and cannot cause even a mild form of meningitis or septicaemia. 3  There are no new ingredients in the vaccine.
