How do you feel about people who adamantly refuse to have the Covid vaccine ?

There is an old saying in the aviation industry. There are old pilots and bold pilots but there are no old bold pilots. I tend to err on the side of caution. Yes there is a disease that can be deadly for about 1/2 of 1% of the human population. The deaths are almost all among the frail and those with several co-morbidities. Therefore my chances of dying from the disease is very small. Given that I don't even know anyone who has had the disease... Then there are the vaxes. I have a wide circle of friends and acquaintances and in that circle I know of 5 very adverse reactions to the vax. I also have a doctor friend who says that 60% of his ER patients are there as the result of the vax. Now what was the vax supposed to do?
