we've all seen blatant examples of dis and mis-information by others who have either no knowledge at all, or the demonstrably flawed studies of those who should know better (e.g. HCQ and Masking)...it's a very easy decision for me...and frankly for virtually everyone I know or come in contact with.
More to your points, though...this is not "the Flu"...the Seasonal Flu never came close to overwhelming or HC systems...did it?...Also...even though 80% of COVID deaths involve those over age 65, that still leaves 20% under 65, or 180,000 people in just 2 years...probably 2X the number of all automobile fatalities...that get's my attention, for sure....plus, there are the "Long COVID" sufferers.
But let's again pull back...vaccines are free...easy to get...and super safe...what could possibly be the reason not to get vaccinated?...it's an extremely easy calculation to make for all age groups...not more challenging than getting a MMR shot, or a Polio shot...really.
