- Medical researchers around the world are testing live polio vaccine for a secondary ability to prevent COVID-19 (coronavirus) for a short time.
- Proponents say this could hold humankind over until a true vaccine is developed.
- Scientists don’t understand why live vaccines have this effect, but they speculate it’s a broad immune response.
Medical researchers suggest there could be a stopgap way to reduce the spread of COVID-19 (coronavirus). They’re cautiously discussing and beginning to test a secondary effect of the “live virus” polio vaccine as a way to prevent transmission.
This effect isn’t a true vaccine, or effective for nearly the same length as a vaccine, or even a treatment of any kind. But when someone is inoculated with the “live virus” polio vaccine, they almost always have extended immunity to many other viruses for about a
