BOOST THE IMMUNITY: Booster doses are given to boost the immunity.It is really an extra vaccine which is given after the earlier dose. After initial immunization is completed in case of Measle initial dose is given at12-15month of age as MMR and in case of polio 3doses at2-4-6month age and4th dose15-18month age Boosters for both4-6Years of age Boosters are given to increse the immunity to protective level

Assurance: Vaccines for these and many others are seldom as helpful in generating immunity as the wild disease. Since they are better for the patient than getting the disease, it is what we have to offer. Sometimes a percentage of the first dose will have no effect, or the effect on building antibodies will not last long. Boosters push the body to do its best and give longer protection.
