We take the safety of our audience seriously.  Although vaccination does greatly reduce the risk of serious illness, the effectiveness of the original vaccine at reducing transmission has diminished as COVID-19 variants have evolved with increasing transmissibility, and it now provides little protection against infection, especially if several months have passed since the last vaccine dose.  As this has become more clear, we no longer feel it is necessary to require our audience to provide proof of vaccination.  However, the evolution of more contagious variants highlights the importance of wearing a good mask when attending indoor gatherings, so we do recommend that our audience wear masks when possible.  Currently, masks are recommended, but not required.  However, this may change if the COVID-19 situation worsens.
