Abstract: Immunization status of children in Chinnamanur and Cumbum area were studied. It was noticed that extended package of vaccination and oral polio vaccination coverage reaches 100%. But the immunization rate declined dramatically with increase in age of children. The study clearly shows there is a positive correlation between the parent’s education and immunization coverage. But in some cases educated parents fails to vaccinate their children after eight years. Promotion and creating awareness to the parents about complete vaccination may reach cent percent in future to create disease free society.
