Not just at seventh fleet... We just had our first shot-ex, and I found out the students all had to answer the same questionnaire, whether they wanted the vaccine or not. It's really no different than addition by subtraction tho, not hard to delineate who chose to vaccinate and who didn't. Having folks DECLINE the shot, which still is optional, certainly buys some protection from lawsuits.
I'm just hopeful that once all have been able to that wanted it(in their respective squadron/base location), they will reduce the masking rules (for all; in squadron spaces) and out in town rules (at a minimum for those that took it; ideally for all though). Not beyond whatever the local government has set obviously, but at least ditch the FRAGORD. If you took the vaccine, or chose not to, it's time to get back somewhat to normal (I'm not saying to ignore local mask edicts in town if they exist, or to choose to take a trip (although the mil should have nothing to say on this choice barring operational necessity to decline your leave) to infect a high-risk grandma that isn't vaccinated, etc). Everyone (in their respective military location) will have had the ability to grab a vaccine if they wanted it, or decline it if they wanted to wait for more data or until it becomes mandatory. So we can start treating all of these people, like, ya know, the adults they are.
