Vaccine reluctance & General COVID Discussion - #8695 by MaineLonghorn is a cautionary story of someone in a wedding party superspreading to others in the wedding party (including the bride and groom) during pre-wedding activities, resulting in the cancellation of the wedding.
What is means is that it would be a good idea for the people in the wedding party to self-test before each contact with others during pre-wedding activities together, as well as just before the wedding. Yes, tests are not perfect, but testing before contact during pre-wedding activities would reduce the risk of a superspreading event just before the wedding.
