Not completely true.
My daughter, who is always out and about, caught the Flu over Thanksgiving week and was pretty sick, unfortunately.
Hubby and I caught the flu Election week. since then it has turned into a touch of pneumonia. The coughing is the most annoying. We have meds and have been taking vitamins; to a lesser extent ivermectin.
Agree, Wife went to World Series and brought it and COVIG back,,,been ages since I have had the Flu,, but this one is bad,, add in COVIG,, which to me is just kinda of pain in the ass,, no taste, tired sleepy,,,, but been rough 3-4 weeks so far. And pretty much everyone in family has had a dose of it.
