I will be flying to visit family on the 11th day after my second covid shot. My parents (mid/late-70's) will be fully vaccinated at that point. They live in a small unit and have offered to let me sleep on their couch. Is there a rough estimate of what the risk I'd introduce to them would look like?
I have other options for places to stay. One or both of my parents is medically fragile. They are thrilled at the thought of slumber parties with me. Of course, I'll be on airplanes for hours; I don't want to take any chances but I'm not sure if I'm being *too* careful.
(Also, I don't endorse traveling for leisure at this time. I have a rare opportunity to see them; it's been a couple years and it'll be a while til my next opportunity.)
