1. You keep telling us what great shape you are in. We are suitably impressed.
2. Did you finally have the SARS-CoV-2 antibody test?
3. There is data the antibodies one gets from having infection are NOT as good as from the complete vaccination series. That's why nearly all experts are recommending even people who've had COVID get vaccinated.

Is immunity from the vaccine stronger than natural immunity from infection?
“The first time your body sees the spike protein, it activates some immune system cells to begin to recognize and develop antibodies against that protein,” said Boslett*. The response may be similar whether that first encounter is from infection with the virus or from the first dose of the vaccine.
Studies of the mRNA vaccines suggest that one dose may offer between 50 to 80 percent protection against symptomatic COVID-19, though more data is needed, said Boslett. “We know you get some amount of protection after one dose of the vaccine or after infection with the virus, but we don’t know in either case how long that protection lasts,” she said. Some cases of reinfection have been reported after three to six months, so the protection from one dose of the vaccine also may wane in that timeframe.
“However, when you get the second dose of the vaccine, you’re further training your immune system,” said Boslett. “You’re strengthening that response from the antibody-producing B cells and you’re also activating T memory cells that stick around for much longer.” Getting both doses of the vaccine means your body is shown this spike protein multiple times in a short duration. “So that immune response might be bigger, better and longer lasting than just getting the infection one time,” she said.
Because the booster effect is so important, Boslett adds that this is why people who have had COVID-19 are still recommended to get the vaccine.
