Immunization against Vaccine preventable Diseases...

Immunization is the process of stimulating immunity against a particular disease. It involves administration of vaccines.
There are vaccine preventable diseases like;

Poliomyelitis caused by the polio virus
Hepatitis B caused by hepatitis B virus
Tuberculosis caused by Mycobacterium tuberculosis
Pertussis caused by Bordetella pertussis
Diphtheria caused by diphtheria species
Tetanus caused by Clostridium tetani
And a host of others according to the National schedule on immunization.

However, more vaccines are incorporated into a vaccina, hence, there are now polyvalent vaccines or trivalent vaccina. See the recommendations as stipulated by the American Association of Pediatricians, on influenza vaccine... American Association of Pediatricians guidelines on influenza vaccination.
