I got the new Pfizer Omicron COVID booster almost three weeks ago. I still wear a mask when I go into public spaces, but with ever booster I hope I'm more resistant should I come into contact.

I heard a news story this week that said there may be about 10% of the population (US? World?) that has immune systems that use exposure to past corona viruses (colds) to combat exposure to the new corona virus, so they fight it off early and don't develop symptoms. Everyone else has to get exposed, let their immune systems start making the antibodies, then fight it off (hopefully) after symptoms have developed. I look forward to more information about this.
