You made me think, as I often do, about one of my choir directors. She a fantastic musician, very exciting, challenging, and fun to work with. She is an anti-vaxxer. This sort of complicates things in terms of getting back to singing and performing. I have no worries for myself as I have been fully vaccinated but there is the audience to consider. The rest of the choir either is or plans on being vaccinated except for one member who is also an anti-vaxxer but had COVID-19 & thus possesses a degree of immunity, even if it is not as good as that afforded by vaccination.
