This is unfortunately true about some people. The problem with your statement is that you don't specify which people you are referring to.
People who refuse to leave their house, who are afraid to go within hollering distance of another human being, even after getting the vaccine, even with wearing masks, etc. fit this description. People who are constantly scrubbing themselves, their clothes, and all the surfaces in their house fit the description. I have a friend who fits this description. I told her that even though she will never catch Covid (how could she?), she has let the virus win anyway. People who are terrified of getting an extremely safe vaccine fit the description.
But what about the great majority of Americans who by now have gotten the vaccine? We are out and about, mingling, shopping, dining in restaurants, enjoying each other's company. My entire family is going together on a beach vacation in a couple of weeks. We've all been vaccinated, except for the few who are too young, and we're planning to observe realistic caution. We're bringing tons of games, sports equipment, and food, cooking delicious meals to eat at our rented house, walking to the beach (we're three houses in from the beach, even elderly me can manage that), taking joy in seeing each other and breathing the delicious salt air.
So, while nobody is "worrying about dying," we are exercising normal precautions. We are not suicidal. We all got vaccinated as soon as possible and feel blessed that we were able to do so.
If anybody does encounter a virus or two, either we will not get sick from it, or will have a mild case. And that is the whole point of the vaccine, which anyone who reads a newspaper or watches a news broadcast knows by now. It's obviously too soon to know long term effects, but we can try to make intelligent choices based on what we know now.
And what we know now is that the vaccine seems to be amazingly effective against a killer of a disease with an even worse new variant The vaccine has few or no bad side effects, for about 99% of us. That's good enough odds for me. And that is not"worrying about dying," it's the exact opposite. The people who have been vaccinated do not have to worry about the disease at all. In our family's vacation plans, the word Covid doesn't even come up!
