> If the numbers get close to flu numbers people will want to know why we don't shut the economy down every year for the flu.

My initial guess would be the existence of a flu vaccine.

The flu vaccine is not a true vaccine. It's a best guess vaccine at how the virus has mutated, and is often ineffective.

My comment had nothing to do with efficacy. It’s a guess at why public panic over standard flu cycles does not occur.
