Advisory Committee on Immunization Practices (ACIP) Recommendations
Infants and Children
• All infants without contraindications should receive 3 doses of inactivated polio vaccine (abbreviation: IPV; trade name: Ipol®), given at least 4 weeks apart, with the first dose administered at a minimum of 6 weeks of age, routinely at 2, 4, and 6-18 months of age.
• A fourth dose is recommended at 4-6 years of age, though this dose is not needed if the third dose was received after 4 years of age and at least 6 months after the second dose.
• A full primary vaccination series with IPV is also recommended for adults at increased risk of infection (such as international travelers to epidemic or endemic countries, members of communities or groups with disease caused by wild polioviruses, laboratory workers who handle specimens that may contain polioviruses, health care workers who have close contact with patients who may be excreting wild polioviruses, and unvaccinated adults whose children will be receiving oral poliovirus vaccine, although there is no oral poliovirus available in the United States at this time).
• For adults at high risk of exposure, who have previously been fully vaccinated as children, a one-time additional dose of IPV is recommended [1, 2].*

Important Information for Obstetric Providers
- Polio vaccine is not routinely recommended during pregnancy.
Poliovirus is an RNA enterovirus of the Picornaviridae family. Transmission is primarily through the fecal oral route, and the virus replicates in the pharynx, local lymphatics and gastrointestinal tract. Spread of the virus from blood to nerves to the central nervous system can cause destruction of motor neurons. The incubation period is 3-6 days for nonparalytic poliomyelitis and 7-21 days for onset of paralysis in paralytic poliomyelitis. Up to 72% of all infections in children are asymptomatic, but these persons can shed the virus in their stool and respiratory secretions and transmit the virus to others. Approximately 24% of infections in children result in minor, nonspecific illness without viral spread to the central nervous symptoms, followed by complete recovery within a week. 1-5% of infected children experience nonparalytic aseptic meningitis, lasting between 2-10 days. Paralysis occurs in less than 1% of infections in children. Paralytic symptoms typically progress for 2 to 3 days then plateau as the fever subsides. Many of those with paralytic poliomyelitis recover completely, and most recover some muscle function. However, any paralysis or weakness that persists after the first year is generally permanent. Paralysis predominantly affects the proximal muscles, especially of the legs in an asymmetric fashion. Between 2-5% of cases of paralytic polio in children and 15-30% in adults die from the disease, primarily because of paralysis of the muscles of respiration .Vaccine
Inactivated poliovirus vaccine (IPV) is formaldehyde-inactivated and contains all three serotypes of polio vaccine virus. Combination vaccines that contain IPV include DTaP-IPV (trade names: Kinrix®, Quadracel®), DTaP-Hep B-IPV (Pediarix®) and DTaP-Hib-IPV (Pentacel®) . The following is a direct excerpt from the 2009 ACIP recommendations which clarifies the vaccination schedule to be used for specific combination vaccines:
“When DTaP-IPV/Hib (Pentacel®) is used to provide 4 doses at ages 2, 4, 6, and 15–18 months, an additional booster dose of age-appropriate IPV-containing vaccine (IPV [Ipol®] or DTaP-IPV [Kinrix®]) should be administered at age 4–6 years. This will result in a 5-dose IPV vaccine series, which is considered acceptable by ACIP. DTaP-IPV/Hib is not indicated for the booster dose at age 4–6 years. ACIP recommends that the minimum interval from dose 4 to dose 5 should be at least 6 months to provide an optimum booster response.” 
Oral poliovirus vaccine (OPV) is a live-attenuated vaccine that is no longer used in the United States .
Vaccine Effectiveness: At least 90% of recipients of two doses of IPV develop immunity to all three poliovirus types, and at least 99% develop immunity after three doses. The exact duration of immunity is unknown but appears to be long term .
Vaccine Safety: Minor local reactions such as pain and redness occur occasionally occur after receiving IPV .
Contraindications and Precautions: Polio vaccine is not routinely recommended during pregnancy.
Considerations for Women of Child-Bearing Age: Polio vaccine is not routinely recommended during pregnancy.
Although no adverse effects of IPV have been documented among pregnant women or their unborn infants, vaccination of pregnant women with IPV should generally be avoided. However, if a pregnant woman is at increased risk for polio infection and requires immediate protection, IPV can be administered in accordance with the recommended schedule .
