"It ain't over till it's over."
We are about 50% vaccinated nationwide -- over 65 about 74%, 16-24 40% with percentages decreasing with age. Should the vaccinated be concerned about the unvaccinated ? Assuming the unvaccinated have access to the vaccine, no, we are not responsible for people making bad choices. If we know or are related to an unvaccinated person we need to get that person vaccinated especially if they are older. If they died you will forever feel responsible.
