Although there is currently a polio vaccine, researchers from the University of Southern California have successfully developed a polio vaccine that does not have to be refrigerated.
The new temperature-stable vaccine could potentially eradicate polio worldwide. While the disease has long been eradicated in most countries, some regions still struggle with outbreaks. Some countries, like Papua New Guinea, are experiencing a resurgence of the disease. Nigeria and Pakistan, where constant refrigeration is not always possible, could make strides in polio prevention with the new vaccine.
This new vaccine is promising because the current vaccine has caused damaging effects in these areas. The oral vaccine contains a small amount of the live virus. Vaccinations can then occasionally turn into a form the virus that can cause paralysis instead of preventing polio.
