Polio immunization (vaccine) DefinitionPolio immunization protects against a severe, paralyzing disease caused by poliomyelitis. InformationPolio is a severe, contagious, life-threatening disease of childhood that can cause lasting paralysis, usually of the legs. It usually affects children under five. The entire body, including the breathing muscles, may become paralyzed within hours after the onset of the illness. This can be deadly if the child is not placed on a ventilator for artificial respiration. No polio has been found in the United States for more than 20 years, but polio is still common in some parts of the world. In a sense, the disease is only one plane flight away -- it would only take one case of polio entering from another country to bring the disease back to the US. Anyone who has not been vaccinated would be at risk. Experts hope polio will be eliminated worldwide in a few years, and that soon these vaccines will no longer be necessary. In the meantime, this vaccine is important. The Salk vaccine is an inactivated polio vaccine (IPV) that was developed by Dr. Jonas Salk in 1955. It consists of injections of inactivated (dead) polio virus. IPV cannot cause polio.
Immunization Schedule:Polio vaccination is one of the recommended childhood immunizations and vaccination should begin during infancy. Children should receive four doses of IPV: one dose each at ages 2 months, 4 months, 6-18 months, and 4-6 years. Children who have received three doses of IPV before age 4 should receive a fourth dose before or at the time of school entry. The fourth dose is not needed if the third dose is given on or after the fourth birthday. The first and second doses of the IPV are necessary to provide a primary immune response, and the third and fourth doses raise the strength of the antibody to high levels. Once the initial series of vaccinations is complete, adults are NOT routinely given booster vaccinations unless they are likely to be exposed to the disease (for example, if they plan to travel to an area where polio is currently occurring). For almost everyone, the benefits of vaccination far outweigh the risks.
Precautions And Contraindications:People who have had severe allergic (anaphylactic) reactions after a previous dose of IPV, or to streptomycin, polymyxin B, or neomycin, should not receive IPV. If a pregnant woman is at increased risk for infection and requires immediate protection, IPV should be administered in accordance with the recommended schedules for adults. Although have been no reported adverse effects in women who have received IPV during pregnancy, IPV should be avoided during pregnancy if possible. IPV can be given to the following people who might have some concerns about vaccination:
Anyone who:
People who are moderately or severely ill should usually wait until they have recovered before receiving the vaccine.
Postimmunization Symptoms And Care:IPV may cause mild soreness and redness at the site of the injection. This is usually not severe and lasts only a few days. There are usually no other symptoms and no other care is needed after immunization.
Call The Primary Health Care Provider If:You are uncertain whether polio immunization should be given, particularly if there are conditions where immunization may need to be delayed or not given. An allergic reaction or other symptoms develop after polio immunization. You have other questions or concerns about polio immunization.
