Well, my wife works at the VA here in Tucson (one of the larger class) and the Head ER doc and Chief of Staff were on the staff call today.
As of today, they have the highest number of both employees and patients being positive. The sickest and ones admitted were not vaxed or boosted. Those not admitted were vaxed, and had the equivalent of head cold symptoms but no lung infections or issues.
I'm in a fairly high susceptibility group, so I got the J&J (not too trusting of the mRNA versions), will likely get boosted this week or next.
(full disclosure: she got the Moderna (mRNA) vax and booster, and her antibodies are sky high. Mine are 'meh')
YMMV
