What recently happened with a polio vaccine that was injected in a patient?
Vaccine Strain Polio Death in Minnesota The live virus Oral Polio Vaccine (OPV), which is no longer used in the US but is used in places like India and Nigeria, can lead to actual polio infections both in those who get the vaccine and in others who can catch the disease from those who are “shedding” the virus after the vaccine. This is a case where someone came into contact with someone shedding polio after OPV. I don’t know why the OPV vaccine is still used at all. It is my understanding that part of the reason polio is still active in India and Nigeria is because they use the OPV.

State health officials are investigating a case of infection associated with the polio virus in a Minnesotan who died last month. The patient was infected with a virus strain found in the oral polio vaccine. The oral vaccine, which is no longer used in the U.S., contained live polio virus. The injected polio vaccine now in use contains only inactivated virus. The patient died with symptoms that included paralytic polio, but it is not known to what extent the polio may have contributed to the death. The patient had a weakened immune system and multiple health problems. The patient most likely acquired the vaccine-derived polio virus from someone who had received the live-virus, oral poliovirus vaccine (OPV) before the use of OPV was discontinued nine years ago. Infection from polio virus can cause a wide range of symptoms. Most infections result in no or mild symptoms, but in rare cases can severely affect the neurologic system, resulting in paralysis.
