Not a doctor but my suspicion is..probably not unless your isolation resembles a bubble. We still go to the store, eat the food, etc. You have basic immunity at-large but not to the local variations that you catch them when you travel. The local variations evolve without you when you go to antarctica for a while.
The more serious infections (cold, flu, covid) aren't a "gradual" immunity thing, they're individual strains that pack a hard punch in comparison to everything else. In part because we don't see anything super close to them on a regular basis.
