Children are not at risk for serious COVID-19 infection. They never have been. If teachers and staff are vaccinated then what is there to worry about? Additionally, we know that asymptomatic spread did not play a significant role in spreading COVD-19. If children are not displaying symptoms then they are not spreading the virus. Also, why aren’t masks required anywhere else besides school? This makes zero sense unless of course, you ask the teacher's unions.
