Polio vaccines
Oral polio vaccine (OPV)

Inactivated polio vaccine (IPV)
It is an injectable vaccine and can be either administered alone or along with other vaccines (e.g., diphtheria, tetanus, pertussis, hepatitis B, and haemophilus influenza). Generally, three spaced doses are given to generate adequate levels of seroconversion. A booster dose is added during late childhood for polio prevention.
Polio symptoms
Most people affected by polio virus are asymptomatic and do not show any symptoms. While 1 out of 4 people suffering from polio develop mild symptoms like sore throat, fever, tiredness, nausea, headache, and stomach pain. A few people with this virus can develop serious complications of brain and spinal cords like meningitis, paralysis or weakness in arms or legs.
