What is Inactivated Polio Vaccine?
1. What are polio virus and poliomyelitis?
Poliomyelitis is caused by polio virus which enters orally and establishes infection in the intestine. Reproduced polio viruses are excreted in the stool and infect others orally again. In most cases, infections have no clinical symptoms, but induce immunization to polio viruses. However some may suffer from paralysis for their lifetime in their legs and arms caused by the polio virus that has invaded their spinal cords.
2. Inactivated Polio Vaccine (IPV)
IPV is a product made of killed polio viruses. IPV has no virulency causing paralysis but enough potency to produce immunity against polio virus infections.
Classification: inactivated vaccine
Age of the subject: 3 months to 90 months
Frequencies and intervals:
#For initial immunization: 3 times with intervals of more than 20 days
#For booster: added once more (fourth time) 6 months after the third injection
(Recommended schedules are: First three injectionswith intervals of 20-56days. Fourth injection at 12-18 months after the third)
((*As of September 1, 2012, the fourth injection is not included in regular immunization schedules, because the clinical trial for the fourth injection is not completed yet. As soon as the results come out, it will be included aspart ofthe regular immunization.))
