Polio Vaccine for children is a highly contagious viral disease seen in children that can cause paralysis and even lead to death. It most commonly spreads through contaminated water or food and can be deadly if not treated properly and on time. Polio drops are also an important part of preventing polio. The drops contain a small amount of dead virus that helps the body build immunity to polio before infection occurs. More Info : https://pregajunction.com/blog/polio-vaccine-for-children/
