@Anne9956 There has been no research to date that indicates that vaccination means a person can't still transmit the virus to others, only that it confers a certain level of immunity to the person who has been vaccinated.
I also have a home-share listing, have been closed to bookings since early March, and do miss being able to host, but it isn't worth risking my health for. I think we're just going to have to hang tight until there is more definitive science if we want to keep ourselves safe.
