FIRST FEW VACCINES

Vaccination is a simple, safe and effective way of protecting babies and children against diseases. The risks from having these diseases are far greater than the risk of any minor side effects from vaccination. When your child is given a vaccine, their body responds by making antibodies, the same as if they had caught the disease but without getting sick. Then their body produces antibodies to destroy the vaccine and these stay in your child's body and protect them against the actual disease. It takes few weeks for vaccines to work, so immediately your child will not be protected. Also, most vaccines need to be given several times to build up long-lasting protection. For example, a child who gets only one or two doses of the whooping cough vaccine is only partly protected against that disease and may still catch whooping cough. More than one dose of the same vaccine is given
The first dose is recommended within 24 hours of birth with either two or three more doses given after that. This includes those with poor immune function such as from HIV/AIDS and those born premature. The vaccine is given by injection into a muscle. Monovalent hepB vaccines should be used for doses administered before age 6 of 6 weeks. Administration of a total of 4 doses of HepB Vaccine is permissible when a combination vaccine containing HepB is administered after the birth dose. Infants who did not receive a birth dose should receive 3 doses of HepB containing vaccine starting as soon as feasible. The ideal minimum interval between dose 1 and dose 2 is 4 weeks, and between dose 3 and 4 is 8 weeks. Ideally (3rd or 4th ) dose in the HepB vaccine series should be administered no earlier than age 24 weeks and at least 16 weeks after the first doise , whichever is later. For catch up vaccination, administer the 3 dose series to those not previously vaccinated. In catv=ch up vaccination 0, 1, and 6 months
