Indeed.I was fine with natural immunity for 2 years until omicron came along.
After getting omicron I was around a lot of people with covid and haven't gotten it again.I think omicron natural immunity is as good as the originals natural immunity
Shot out to the vaccine though my vaccinated mom breezed though covid with no problems while she lost a friends and relatives around her age before the vaccine was available.
GWB told us antibodies were out in 40 days!!!
