I didn't take the jabs, but I did have COVID-19 Delta. It was no fun and took a while to fully heal from (it caused a unique form of lung scaring that takes a while to heal, but it does heal). Now I'm really immune to COVID and its variants.
Later, after I recovered, certain medical research organizations harvested COVID antibodies from my blood for cloning. The immunity shows up in serology.
To the best of my knowledge, the medical research professionals I work with did not take the jab either.
