No.

Getting sick without already being immune leaves your body trying to speed-run anti-body development, while ALSO fighting the disease using more basic physiological responses.

And even with anti-bodies, you're not actually impervious. You can still get sick with diseases you're "immune" to, as even deployment of disease-specific anti-bodies is a complex biological process that can go wrong, come too late, or not be enough.

Given time, a person can develop "immunity" against a lot of stuff, but that still doesn't mean every cell in your body is then changed in a way where that pathogen just bounces off.

You see this most recently with Covid, as people who are vaccinated still get infections, but unlike with unvaccinated people, the body fights it off in a couple days, rather than a few weeks.

But it does still takes those couple days for the latent immunity to kick in, and for the body to deploy that defense.

Another person already commented on how different components of the immune system respond differently, and might even be what kills you faster than the disease.
