@Stephanie1954 Stephanie, I am considering two similar versions, one requires proof. I need to decide which. I will put it at the beginning of the "Description" of my house.
"Because of the dangerous Delta variant, although we are fully vaccinated, we are receiving only those guests over age 12 who can prove that they have been vaccinated just as we have been."
"Because of the dangerous Delta variant, although we are fully vaccinated, we are receiving only those guests over age 12 who have been vaccinated just as we have been."
I believe I can ask people to show this as a condition of staying at my house. There is no law that obliges them to provide this proof, but there is also no law requiring me to let them stay at my house!
I can deny smokers. Why can I not deny people who can spread a deadly disease?
