Here’s a military policy anecdote. I attended a gathering (permitted by regulations) with pretty much every officer in my unit. Two days later, one guy (fully vaccinated) tested positive on a random test. I’m currently on orders, and since I’m not vaccinated, I now have to “ROM” and save some gas money by staying home. The other officers that are vaccinated still are expected to go in because they’re not showing symptoms. When I asked why fully vaxxed and no symptoms don’t need a test, why are we testing someone who is fully vaxxed and showing no symptoms to begin with? Shoulder shrug.
