I asked my dental hygienist if she was vaxxed. She said she got the first shot to keep her job, but no more after that. IDK what guidelines are in your state or demands on employees at that office, but it appears not all are necessarily "fully" vaxxed. My dentist put freestanding HEPA filter systems in his office and rooms. He said they had some sort of spray disinfectant that (claims it) destroys viruses that they spray on their carpets and to wipe down the furniture.
