Is it possible to prevent polio? Is there a polio vaccine?
It is possible to prevent polio with vaccination; vaccinating individuals, especially young children, can establish lifelong immunity to the disease. The inactivated polio vaccine needs to be given at 2, 4, and between 6 and 18 months of age with a booster between ages 4-6. In 2002, the inactivated polio vaccine was approved to be used as a shot combined with diphtheria, tetanus, pertussis, and hepatitis B vaccines. However, the CDC still recommends that people traveling to countries were polio is present receive a polio booster shot before they travel. In addition, those people who care for polio patients need to be sure they have been appropriately vaccinated and still should use strict hygiene when caring for those patients.
Although some people who get the inactivated polio vaccine may have a sore area at the shot site, most people have no problems with the vaccine injection, which usually causes no scar formation. Smallpox vaccines often left a small scar at the inoculation site.
In 2014 in California, an outbreak of an illness that resembled polio was identified. All of the affected children (about 25) developed a rapid onset of paralysis in one or more limbs and MRI findings consistent with injury to the central spinal cord. All of the children had been vaccinated against polio. Some of the children were positive for enterovirus-68, a virus known to be associated with limb paralysis and breathing difficulties. The CDC and researchers are currently trying to definitively determine the cause of this illness although they agree it is not polio. To date, the children, ages 2-12, have not responded to steroid treatments or recovered from the paralysis, according to doctors interviewed about this illness. This new outbreak of polio-like illness is being intensely investigated.
