The Inactivated Polio Vaccine (IPV) is a vaccine used to protect against poliomyelitis, a viral disease that can cause paralysis. IPV contains killed versions of the poliovirus, which stimulate the immune system to produce antibodies without causing the disease. It is administered through an injection, typically in the arm or leg. IPV is part of the routine immunization schedule in many countries and is recommended for children. The vaccine is effective in preventing polio and has contributed to the significant decline of polio cases worldwide, especially in regions where the disease was once common.
