Dad finally getting his J&J today, brother getting his later this week. Dad was/is totally hesitant, but I think enough fox news people have got them for him to feel comfortable with it (which btw, he's actually been fine/ok with masks and WFH, for someone who is a trumper, he's fairly even keel all things considered).
Brother is just thinking he's invincible, not really hesitant, just didn't think he needed it, but now is willing to just be done with it.
Both I think wanting to get it so they don't have to wear a mask anymore and feel justified in doing so
