When is the right time to start getting Polio drops for kids?

Polio is a disease caused by a virus that first stays in the throat of a human and then goes in the intestinal tract. In the year 1955, polio had become a pandemic in the US and become the reason for many people's disabilities. Although this disease has been eradicated from most of the countries, still it poses a threat to many developing nations. Therefore, polio vaccination is one of the most important childhood immunizations. Polio vaccine (IPV- Inactive Polio Vaccine) is given in four doses. First dose at two months. Second dose at four months. 3rd dose at 6-18 months and fourth and last booster dose at 4-6 years. Thus, you should get your kid's vaccination done before the age of 6.
