You're not going to get COVID antibodies via the vaccines. You would with other vaccines (e.g., polio, measles, etc.), where they inject the actual disease into your body in order to trigger your body's natural immune response, but the mRNA vaccines don't work that way. The only way to get COVID-19 antibodies currently is to get the disease.

I'm not vaccinated and it is by choice because I've already had COVID. Getting a vaccine for a disease you've already had is like wearing two pairs of pants. Sure, you can do it, but why?
