Natural immunity will almost always trump immunity from a vaccine. It's not just the antibodies, it's IgA, B&T cells, IgM, and IgG. At this time, my recommendation to my patients is to not get vaccinated if you already had COVID. That recommendation may change based on the variants we see in the future and as more data comes in on the vaccines. Each vaccine isn't the same so some are better or worse than the others. My concern is that the viruses mutate to a form that can enter the cells in other places than the ACE2 receptor. I believe the Delta variant is such an example as at least one study on heart cells showed the virus entered through CD147 receptors.
