I know nothing about polio, but is this demonstrably true, is polio seen to be mutating, and it is considered a real risk by scientists that a strain could emerge that is invulnerable to vaccines?
- mikeyouse 7y agoPolio can definitely mutate to forms resistant to the vaccine. An outbreak in the Congo in 2010 resulted in 450 infections with a nearly 50% mortality rate. When scientists tested the strain on samples, they estimated that ~20+% of the population would still be susceptible in a fully vaccinated group.
