Polio vaccination is the primary strategy for eradication. There are two types of vaccines: the Oral Polio Vaccine (OPV) and the Inactivated Polio Vaccine (IPV). OPV is administered orally and provides immunity in the intestines, which helps prevent the spread of the virus. IPV is injected and offers strong immunity in the bloodstream. Both vaccines are safe and effective, with OPV being more commonly used in mass immunization campaigns due to its ease of administration and cost-effectiveness.
