My sister had about 15 people over on Mother's Day. My dad and I went because we're both vaccinated. My sister and her mil are also vaccinated. Everyone, literally every single person who attended that party, who is NOT vaccinated just tested positive for covid-19. My sister, dad, sister's mil, and I are fine. In case you're wondering if the vaccine works. My sister's husband had been teasing her about getting the vaccine, so she's feeling pretty smug right now, while he's sick on the couch.
