Eh, my experience is different. My sister was living with me at the start of Covid. She's a nurse at a community hospital in a poor large city neighborhood. March/April 2020, we followed the Contagion protocol (scrubs get tossed into the washer and her way to the closest shower from the garage). I heard about the n95s getting reused for a week at a time. The running out of PPE, the unknown treatments, the Xrays of broken glass lungs being more reliable that any test, ventilators needed, finding out only 10% will survive the ventilator, the hospital running out of body bags.
Getting COVID ourselves in Aug 2020, being miserable for a week, then one day taste went away for the next week, the mental fog...
All the while, I had a surgery complication from prepandemic that wasn't getting better. My follow up care was delayed for a few months while the hospitals dealt with the first wave. The covid protocols evolving. The timing of the eventual revision surgery to beat any winter surge. A surgery recovery unit that prepandemic had folks walking multiple times per hour as a means to encourage everyone to get up and move. Now that same unit a year later had folks walking laps in their room.
I am thankful for the vaccine. I didn't want to deal with covid again. Once Delta had some breakthroughs, I still was thankful that the vaccine provided protection against hospitalization. Same with Omicron. I've made peace with living with Covid. That peace was made easier with vaccines. Yes those vaccines are riding on top of whatever is left of my preexisting "natural" immunity.
In short, if your vaccinated and relatively healthy, omicron shouldn't worry you. If you haven't had covid and/or the vaccine well traveling is a risk. If you wanna better your odds of staying out of the hospital, get vaccinated. You still might get it, but odds are better that you won't end up in the hospital.
