Immunisation is the process of giving vaccines to the baby with the intention of stimulating the defense mechanism against infectious diseases. These vaccines are killed or weakened virus and whole or part of bacteria. They are given mainly by injection (either into the muscle or beneath the skin) or through the mouth. Immunisation protects the individual and community from disease outbreaks. The side-effects of the vaccination are uncommon and are usually mild.

The WHO Vaccine Preventable Diseases Monitoring System maintains a very useful website containing each country’s different immunisation schedules by antigen and selection centre (http://www.who.int/immunization_monitoring/resources/en/).
