We both just got our 5th vaccination and really don't care whether other people are vaccinated or not anymore. We got the shots so we could get out and enjoy what's left of our lives. However, we have not had a cold since January 2020 because we have been wearing N95 masks and we will continue to do so when in close quarters, like a theater, with people we don't know. By the time we sail in December we will have had our flu shots also.
