Children are usually advised 4 doses of Polio Vaccine. The first dose is given at age of 2 months and then the next doses are given at 4 months, 6–18 months and 4–6 years, respectively. However, sometimes Polio Vaccine is given in a combination vaccine along with other vaccines. In this case, a child might receive a fifth dose of Polio Vaccine. Adults, on the other hand, do not need to get vaccinated if they have already been vaccinated as a child.

Polio Vaccine contains live attenuated poliovirus (strain types 1, 2 and 3) and is intended for polio prophylaxis in infants 6-12 weeks of age, all unimmunized children up to 18 years of age and high-risk adults. Adults, however, should receive the inactivated poliovirus vaccine (IPV).

Polio vaccines are vaccines used to prevent poliomyelitis (polio). There are two types of polio vaccines, one is inactivated poliovirus vaccine (IPV) which is given by injection and the other is weakened oral poliovirus vaccine(OPV) given by mouth.

Yes, polio virus attacks the nervous system which can lead to paralysis, especially of lower limbs. Therefore, it is important to get Polio Vaccine as it provides protection against this virus.

No, IPV is considered more effective than Polio Vaccine. Although, it is expensive and relatively difficult to administer. It was seen that giving Polio Vaccine alone led to more cases of polio when compared to Polio Vaccine because it is a live form of the virus. Therefore, in order to prevent polio outbreaks, Polio Vaccine is the preferred form of polio vaccine.
