That makes sense.Quote:
Of course it's possible, that's what Virus's do. If you've ever looked into Smallpox you'll know how awful it was. Some estimates suggest that it killed 20% of ALL humans that were ever born for nearly 3000 years. It mutated so fast and was so virulent (sic) that humans simply couldn't build up resistance to it fast enough.
However, corona viruses are a different kettle of fish. We know enough about how they work now and can predict with some degree of accuracy what's going to happen. Not 100% of course, but the science is there. The biggest weapon we have against large mutation is a vaccine, simply because it pushes the R number down so low that it simply can't spread.
We experience small mutations in the flu virus every year etc, but the immune memory from the last strain is almost always enough to not produce pandemic level problems.
