@Priscilla150, your house, your rules. Given that your listing is your own home, I think it's reasonable to require proof of vaccination. I do think you need to be specific about COVID-19 vaccination, however, because 'proof of vaccination' is a bit ambiguous. You could say something like, 'all guests will need to show proof of COVID-19 vaccination'. However, you still need to protect yourself because vaccination doesn't give 100% protection, especially against the delta strain.
