Immunization refers to the artificial induction of immunity. It can be by (i) Active Immunization: the use of live attenuated infectious agents or inactivated toxins, or antigens obtained by genetic recombination OR (ii) Passive Immunization: temporary immunity obtained by the administration of immunoglobulins or antitoxins. Certain vaccines are routinely recommended for all infants and children. These include Diphtheria, Pertussis and Tetanus (DPT), Measles-Mumps-Rubella (MMR) and Hepatitis B. H.Influenza (Hib) and varicella vaccines are optional. Every effort should be made to ensure that all children are immunized.
