All of my friends' kids who are in daycare get sick frequently. I work on the top floor of a building that has a YMCA daycare on many of the bottom floors, and I often get sick passing through there on the way to work.
I think Covid showed pretty definitively that avoiding illness through extreme social isolation is not worth the costs in emotional and social development.
Unless the child is immunosuppressed, outside of a novel pandemic scenario, a vaccinated child is not likely to contract a very serious infection beyond the common cold or flu by being in childcare. Much of that can be mitigated by giving parents the flexibility (sick leave) to keep their children home while ill.

Perhaps you are uniquely susceptible? I don't think this generalizes to most people if they practice public hygiene habits like washing your hands when arriving at the office.
Outside of society being oriented around having my wife work and sending our son to daycare rather than having her raise him at home, everything's going great so far, one year in.
Probably just the common cold most of the time. My nose was runny through most of my childhood too. And kids are snotty - always have been - it's not necessarily a condition that needs to be fixed. If it's bothersome to you, then of course avoid group childcare.
Also, some diseases like chicken pox are preferable to contract as a child and gain immunity to then - since they are far worse symptomatically to contract as an adult.
