I have had two covid shots, Moderna, and three boosters. I had Covid in the beginning of the outbreak, lost 15-20 lbs., ans self quarantined for two weeks. Took me three months to gain back 10 lbs. I was going to get another booster before Alaska, but didn't. On each plane there were many people coughing. I will get another booster after I see my lung doctor. After 60, your health should be your first priority. One more thing, do not fall down, period. My doctors always ask that question, and I know people who have fallen. So much shit.
