IPOL Vaccine Description

IPOL is a sterile suspension of three types of poliovirus: Type 1 (Mahoney), Type 2 (MEF-1), and Type 3 (Saukett). IPOL vaccine is a highly purified, inactivated poliovirus vaccine with enhanced potency.

Sanofi Pasteur's single-antigen IPV (IPOL) is distributed in single-dose syringes or 10-dose vials. Some combination vaccines (several different vaccines in the same shot) contain IPV, such as Pentacel (DTaP-IPV/Hib),

Most adults do not need a polio vaccine because they were already vaccinated as children. 

Children in the United States should get an inactivated polio vaccine (IPV) to protect against polio or poliomyelitis. Children who will be traveling to a country where the risk of getting polio is greater should complete the series before leaving for their trip.

The recommended dose for both children and adults is 0.5 mL. It can be administered by the intramuscular or subcutaneous route, using a needle length appropriate for the age and size of the person receiving the vaccine, says the U.S. CDC.

Polio is a highly infectious disease caused by a virus. It can invade the nervous system and can cause total paralysis in a matter of hours. The virus enters the body through the mouth and replicates in the intestine. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck, and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Among those paralyzed, 5% to 10% die when their breathing muscles become immobilized, says Sanofi.

IPOL Vaccine Indication

The IPOL vaccine is indicated for active immunization of infants (as young as 6 weeks of age), children, and adults to prevent poliomyelitis caused by poliovirus types 1, 2, and 3.

Routine primary poliovirus vaccination of adults (generally those 18 years of age or older) residing in the US is not recommended. However, unimmunized adults who are potentially exposed to wild poliovirus and have not been adequately immunized should receive polio vaccination. Persons with previous wild poliovirus disease who are incompletely immunized or unimmunized should be given additional doses of IPOL vaccine if they fall into one or more categories listed.

The following categories of adults are at an increased risk of exposure to wild polioviruses:

Travelers to regions or countries where poliomyelitis is endemic or epidemic.

Healthcare workers in close contact with patients who may be excreting polioviruses.

Laboratory workers handling specimens that may contain polioviruses.

Members of communities or specific population groups with the disease caused by wild polioviruses

IPOL Vaccine Dosage

IPOL is administered intramuscularly or subcutaneously. Single-antigen IPV is distributed in single-dose syringes or 10-dose vials. The recommended dose for both children and adults is 0.5 mL. It can be administered by the intramuscular or subcutaneous route, using a needle length appropriate for the age and size of the person receiving the vaccine.

IPOL is the inactivated poliovirus vaccine that is included in the children's vaccine series Pentacel and Quadracel.

IPOL Vaccine News

December 9, 2020 - According to the latest report from the Global Polio Eradication Initiative (GPEI), 4 countries reported additional polio cases involving vaccine-derived polio. Pakistan: five WPV1 positive environmental samples, six cVDPV2 cases, and eight cVDPV2 positive environmental samples; Central African Republic: one cVDPV2 case; Chad: nine cVDPV2 cases; Somalia: one cVDPV2 case.

December 9, 2020 - Scientists evaluated the two nOPV2 candidates in parallel clinical studies in adults, young children, and infants in two different countries to assess their safety and immunogenicity compared with the licensed Sabin mOPV2 designed to replace them. Designed to be more genetically stable than the licensed Sabin oral vaccine, the new vaccine appears safe. According to the research published in The Lancet, it provides similar immune responses when tested in healthy adults, children, and infants.

November 13, 2020 - The WHO issued an Emergency Use Listing recommendation for the type 2 novel oral polio vaccine (nOPV2).

June 4, 2020 - The world’s largest company devoted exclusively to the research and manufacture of vaccines has discontinued their Poliovax vaccine production, which is produced using a cell line from an aborted child.

December 11, 2029 - FDA: Poliovirus Vaccine Inactivated (Monkey Kidney Cell). IPOL vaccine is indicated for active immunization of infants (as young as 6 weeks of age), children, and adults to prevent poliomyelitis caused by poliovirus types 1, 2, and 3.

March 25, 2015 - Sanofi Pasteur announced that the U.S. FDA approved the use of Quadracel™ (Diphtheria and Tetanus Toxoids and Acellular Pertussis Absorbed and Inactivated Poliovirus; DTaP-IPV) vaccine for active immunization against diphtheria, tetanus, pertussis, and poliomyelitis in children 4 through 6 years of age.
