Omicron is indeed very contagious, but if you’re vaccinated, you have much better chance to survive without much ill effect. I have 2 examples that hit home.
Example 1
My nephew works in hospital. Guess what? He contracted it and had a mild cold-like symptom. CDC says 5 days at home from first day with symptoms then 5 days out with mask on. He was asked by the hospital to be back to work after 5 days at home. He lives with his parents (my brother & sister in-law). They never got sick and tested negative. They were all have been fully vaccinated (Moderna) including booster shot.
Example 2
I ride bicycle about 100 miles / week with my cycling buddies. Two of my cycling buddies (husband and wife) contracted Omicron without symptoms. They were cycling apart from the group for 2 weeks to insure that they won’t spread it to us. We are all have been fully vaccinated, including booster shot.
Knock on wood, I haven’t contracted it. I have been fully vaccinated with Moderna and Pfizer booster shot. I have been on 10 liveaboard trips, 1 dive resort and 1 ski resort in the last 12 months. Got negative Covid test 17 times. Statistically and inevitably, one of these days, I would contract it, but it’s comforting to know that Omicron is just like a mild flu and I would survive it since I have been fully vaccinated
