Infection itself seems to reduce the risk reliably too. I suspect at a similar rate & more durably, especially considering that the vaccine only generates an immune response based on a single sub-unit of a protein. Versus infections where every protein is presented to the immune system.

I suspect the human body responding to that complete antigen is doing something much more complex & effective than an admittedly genius human invention. Perhaps we'd be wise to consider that even our best efforts are often (in ways we don't even understand) inferior to millions of years of evolution.
