Each virus is unique. Polio doesn't evolve the same way cold or flu viruses do.

- ceejayoz 4y agoThe claim above was "Our immune systems can't just 'take a break'... Its a muscle, you don't use it; it atrophies." Polio disproves that conclusively. Your explanation agrees with me here; describing it as a problem with the immune system is inaccurate. Relatively rapid immune escape is a feature of certain viruses.
