Germany had 11 “polio detections”–but the last wild polio CASE was in 1990. All this means is some vaccinated Germans have the vaccine virus in their gut forever, and in their poop.
The US stopped using oral live polio vaccines for this reason in 1999, because all recent cases were due to vaccine-strain viruses that back-mutated to virulence. It has long been known that some vaccine recipients never stop producing the virus. So there is nothing new at all in this announcement.
