You can get vaccines to give your body practice against some of those bugs, but most bugs have no such vaccine. The only way you gain immunity is by getting the illness in the first place. And the immunity will wane with time, for some bugs like flu, you will lose practically all immunity in a year because flu mutates and is no longer recognized by your body. Boosting your immune system outside of having a reasonable diet and exercising is not possible, and if it were, you wouldn't want to do it. Illness sucks because of your immune reaction to something. Making more immune reaction will just make you miserable while not preventing illness or shortening its duration. Sometimes, your over-reaction may indeed kill you. This is exactly what happens with covid via mechanisms like cytokene storm https://virologyj.biomedcentral.com/articles/10.1186/s12985-022-01814-1
In rough order, these are the things you can do to prevent yourself from getting infected by communicable diseases:
1. Avoid people and contact with wildlife
2. Wash your hands regularly. Soap and water are better than sanitizer.
3. Don't touch your face
4. Be careful of indoor air which isn't refreshed often. Sharing air is a major vector for illness like flu and colds.
