Is the polio virus still around today?
Polio does still exist, although polio cases have decreased by over 99% since 1988, from an estimated more than 350 000 cases to 22 reported cases in 2017. This reduction is the result of the global effort to eradicate the disease.
Do adults need a polio booster?
Routine poliovirus vaccination of U.S. adults (i.e., persons aged >18 years) is not necessary. Most adults do not need polio vaccine because they were already vaccinated as children and their risk of exposure to polioviruses in the United States is minimal.

What are the risks of polio vaccine?
IPV has not been known to cause serious problems, and most people don’t have any problems at all with it. However, any medicine could cause a serious side effect, such as a severe allergic reaction or even death. The risk of polio vaccine causing serious harm is extremely small.
How long did it take to get a polio vaccine?
Researchers began working on a polio vaccine in the 1930s, but early attempts were unsuccessful. An effective vaccine didn’t come around until 1953, when Jonas Salk introduced his inactivated polio vaccine (IPV).
Why did they stop using oral polio vaccine?
According to the World Health Organization, routine immunization with OPV must cease after the eradication of poliovirus because of the danger of outbreaks of circulating vaccine-derived poliovirus and the risk of VAPP.
When did they stop giving oral polio vaccine?
The inactivated polio vaccine (IPV) was available first, given as a shot, in 1955. A more convenient form, called oral polio vaccine (OPV), was given as liquid drops via the mouth. It was developed in 1961. OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000.
