It is true that guidance is provided by some trusted sources. such as the CDC and Dr. Fauci. Then the various news outlets provide some perhaps contradictory information. At best, it is clear that there is still much to learn, which leaves us with much uncertainty. It seems that we are largely on our own to weigh the available information and come to our own conclusions.
To do so, perhaps assessing your own tolerance for personal risk might be done by asking yourself some relevant questions and then figuring out the answers with which you are most comfortable. Some questions may concern whom you see: Friends and/or family? Who in particular? Do they have to be vaccinated if age 16 and above? Some questions may relate to where you might go: Going into stores, theater, concerts, gyms, or sporting events? Which ones? Will you eat out? If so, indoors and/or outdoors? Some questions may concern public health measures: Do you get vaccinated? Do you wear a mask? If so, when and with whom? Do you socially distance? What do you do if you are masked around others who are not? What size crowd is OK with you? Another question may be how to respect the preferences of others even when they are in conflict with yours.
Well, you get the picture that there are a lot of decisions you may want to make. What you decide about your personal boundaries will be important to follow in the interest of your personal feelings of safety and wellbeing.
