Honestly not a bit more worried about Omicron than any other variants. Not a lot is known yet of Omicron but it seem to be more transmissible but not as deadly. Everyone will have the virus eventually but as long as hospitalization rate stay low, we’ll be fine. The new normal.
We have to face the reality that maybe one day we’ll have to get booster shots at every few months interval one day & that is fine. Just like how we were supposed to do it with flu shots. Flu shots are done annually & are always ‘updated’ every couple of years.
