Polio Vaccine (IPV) Schedule

Standard Recommended Schedule

The American Academy of Pediatrics recommends that all children should receive four doses of IPV at 2 months, 4 months, 6-18 months, and 4-6 years of age, with a strength of evidence based on multiple citations 1, 2

The Centers for Disease Control and Prevention (CDC) suggests that the first dose of IPV should be administered at 2 months of age, with a minimum age of 6 weeks, and the second dose at 4 months of age, with a minimum 4-week interval from the first dose, based on evidence from 1, 2
The CDC also recommends that the third dose of IPV should be administered at 6-18 months of age, with a minimum 4-week interval from the second dose, though a 2-month interval is preferred, according to 1, 2, 3
The fourth dose (booster) of IPV should be administered at 4-6 years of age, with a minimum 6-month interval from the third dose, as recommended by 1, 2, 3

The CDC recommends that premature infants should receive IPV at the standard chronological ages (2, 4, 6-18 months, 4-6 years) regardless of birth weight, with evidence from 3
Incompletely vaccinated children should complete the series without restarting, regardless of time elapsed between doses, as suggested by the CDC 2
Adults residing in the United States do not require routine poliovirus vaccination, but unvaccinated or incompletely vaccinated adults at increased risk should receive vaccination, including travelers to polio-endemic or epidemic regions, according to 2

Four IPV preparations are available in the United States, including stand-alone IPV, DTaP-HepB-IPV, DTaP-IPV/Hib, and DTaP-IPV, as listed by 1

IPV is contraindicated only in persons with hypersensitivity to vaccine components, such as 2-phenoxyethanol, formaldehyde, neomycin, streptomycin, and polymyxin B, as stated by 3

IPV can be administered simultaneously with other routinely recommended childhood vaccines, including DTaP, Hib, hepatitis B, varicella, and MMR, according to the CDC 2

The Centers for Disease Control and Prevention recommends that all healthy children receive a 4-dose series of inactivated poliovirus vaccine (IPV) administered at 2 months, 4 months, 6-18 months, and 4-6 years of age 4
The American Academy of Pediatrics suggests that the final dose of IPV must be administered at age ≥4 years regardless of the number of previous doses, which is critical for long-term immunity 4

The Centers for Disease Control and Prevention advises that the minimum intervals between IPV doses are 4 weeks for doses 1 to 2, 4 weeks (though 8 weeks preferred) for doses 2 to 3, and 6 months for doses 3 to 4 4
The World Health Organization recommends avoiding the use of minimum intervals in the first 6 months of life unless the child faces imminent poliovirus exposure, as shorter intervals result in lower seroconversion rates 4, 5

The Centers for Disease Control and Prevention states that when using DTaP-IPV/Hib (Pentacel) for doses at 2, 4, 6, and 15-18 months, an additional fifth dose of IPV-containing vaccine must be administered at 4-6 years 4, 6

The American Academy of Pediatrics advises against delaying the fourth dose of IPV beyond age 6 years, as it is essential for long-term protection 4
The Centers for Disease Control and Prevention recommends avoiding the use of accelerated schedules in the first 6 months without specific indication, as this reduces immune response 4, 5
