Sorry Jaime, I don't want to keep going around in circles here which we easily could do. Every one of us has their personal story and for myself I don't think I could bear to see my mom die such a horrible death while I could have done something to help.
The flu itself is probably an even deadlier little bugger, with past pandemics (SARS, MERS, etc) once they ran their course they were over and done with. The flu has thousands of strains, most flu shots are based on the data we currently possess and end up being effective for anywhere between 50-75% on good years. It's almost impossible to fight while we live our lives normally and living in a bubble isn't the answer either. The flu just lives with us, we know it's potential and we can protect ourselves as required.
With COVID-19 I believe our initial responses were the correct actions to take but soon after we began to understand how this virus spread and reacted to those that were infected, we could have quite easily retracted some of the restrictions that were in place. We have extended these restrictions too far, the economy needs to survive and people need to be able to walk out their front door without fear of receiving a $500 bi-law ticket for disobeying a civic ordinance.
