What is the IPV schedule for unvaccinated children 4–18 years of age?
The schedule for routine polio vaccination of children 4–17 years of age is 2 doses of IPV separated by 4–8 weeks, and a third dose 6–12 months after the second dose. If an accelerated schedule is needed, three doses separated by at least 4 weeks may be given. Polio vaccine is not routinely administered to persons 18 years of age and older.
