Not since the start of covid did we ever shut down the lives of the young and healthy to "protect" the elderly and sick. It still didn't work. If you are still afraid that everything and anything out there will kill you, maybe that's your problem. Worrying about what other people are doing and if they are vaccinated or not must be a terrible way to live your life. The immunocompromised need to take some responsibility for themselves, the rest of society needs to move on with life, without restriction.
