Now that I know such guidance didn't come down to them from above, my guess is they are spreading this BS to try to get their own unit's vax numbers up so that they look good.
As my previous post and Spekkio pointed out, there's still so much data that hasn't even been collected (or can't have been collected, such as long-term safety metrics), that nobody even has the capability we of quantifying how safe it is. Different than any other vaccine any of us has ever taken, this one was created in record time, given a EUA in record time, and fully approved in record time, all with a highly political backdrop (both here and abroad) where scientists/public health officials who are beholden to politicians for money and authority/prestige were no doubt pressured by everyone from government officials to private industry to approve the thing without delay. Meanwhile those same officials are routinely lying to people about other issues involving COVID. Hardly surprising some people are scared to take it, unless you want to bury your head in the sand and say "It's just like every other vaccine, and any other lawful order! Take it or F you, your family, and your future, because if you don't then you have a <0.01% chance of being killed by the virus (if you contract it) and a slightly higher chance of spreading it to other people!" We may not yet be able to quantify every important safety metric of the vax, but we can quantify something like the mortality rate of COVID.. go to
https://covid19risktools.com:8443/riskcalculator and see where the military population sits. Compare that to other things we're vaccinated against, such as Polio (15-30%), Smallpox (30%), Tetanus (30%), Anthrax (20-80% depending on the type), etc.
But all that is irrelevant, ultimately. You are entitled to your risk/reward decision, as
should everyone else. Live and let live.
