This is a fantastic question. The poliovirus detected in Gaza is believed to be vaccine-derived. This means someone was vaccinated with the polio oral live vaccine, and shed it at low levels. It got into the sewage and started spreading to unvaccinated children.

Obviously, sewage = very bad, but specific to the polio virus, does this imply a rethink to the idea that it was a positive to have the attenuated live virus spread indirectly to unvaccinated individuals?
