OPV) an oral vaccine against poliomyelitis consisting of three types of live, attenuated polioviruses. It is given orally, often on a sugar cube, and so is convenient for administration to children and large groups of people. There is still no cure for the disease.
During the race to develop an oral polio vaccine , several large-scale human trials were undertaken. Did vaccines really eradicate polio? How many doses of IPV is needed?

What year did the IPV shot begin? A vaccine consisting of inactivated polioviruses, used to immunize against poliomyelitis. Normally, when you think of scientists developing vaccinations and cures for diseases, you might imagine a sterile hospital and scientific trials.
One used inactivated (killed) viruses. It is easy to imagine several scenarios in which polio could be reintroduced to the United States. If that ever happene the disease could get a foothold if we don’t maintain high vaccination rates,” explains CDC’s Dr.
