Inactivated Polio Vaccine
The Vaccination Schedule
Inactivated polio vaccination is a shot that is given in the leg or arm, depending on the person's age. The polio vaccination may be given at the same time as other vaccinations.
Most people should get polio vaccination when they are children. Children get four doses of polio, at these ages:
- A dose at 2 months
- A dose at 4 months
- A dose at 6-18 months
- A booster polio shot at 4-6 years.
Most adults do not need polio vaccination because they were vaccinated as children. But, in general, three groups of adults are at higher risk for coming into contact with poliovirus and should consider polio vaccination:
- People traveling to areas of the world where polio is common
- Laboratory workers who might handle poliovirus
- Healthcare workers treating patients who could have polio.
Adults in these three groups, as well as those who have never received the polio vaccination, should get three doses of polio vaccine:
- The first dose at any time
- The second dose 1 to 2 months later
- The third dose 6 to 12 months after the second dose.
An accelerated polio vaccination schedule can be used for unvaccinated children and adults, with four-week intervals between the three doses of the primary series.
Adults who are at high risk of coming in contact with poliovirus and who have received the three-dose primary series should receive a booster dose of polio vaccination. Based on available information, adults do not need more than a single lifetime booster dose with polio vaccination.
