I think the guest was right to say that it isn't realistic to assume that we can wipe out the Wuhan Flu entirely, but he thinks that protecting the vulnerable plus getting everyone vaccinated is the way to go (if I heard him correctly). Personally, I think that protecting the vulnerable and achieving herd immunity is the way to go, which involves most everyone contracting the disease and developing a natural immunity. After all, the death rate for the disease is actually extremely low, and we don't really know yet what all the side effects of the rushed vaccines will be.
