Vaccinated college students at many elite schools are the subject of an ongoing experiment — a screening study, in fact. Every week, or twice a week, depending on the school, they are asked to take a test for SARS-CoV-2. If positive, they have to quarantine, and if enough kids test positive, the entire school or campus has an escalation of restrictions. This experiment is being run at several schools across the country, but notably not others. Sadly, this experiment is not technically research. It did not receive institutional review board approval, and the primary purpose is not to track whether it works. Instead it has simply been mandated by the colleges. Also regrettably, it does not have a clear control arm.
