Repeated exposure to colds builds lasting immunological defense.
Repeated exposure to common cold pathogens helps maintain stable, long-term immunological memory through sustained pools of antigen-specific T cells and cross-reactive defense mechanisms.
The retrieved literature consistently shows that exposure to common cold coronaviruses generates stable, long-lasting immunological memory, specifically sustained CD4+ T cell and antibody responses resulting from prior and repeated exposures. None of the papers refute the claim.

Immunological memory to Common Cold Coronaviruses assessed longitudinally over a three-year period pre-COVID19 pandemic. 2022. https://doi.org/10.1016/j.chom.2022.07.012
Demonstrates that steady and sustained common cold coronavirus immune responses are maintained over time from a stable pool of memory CD4+ T cells shaped by repeated exposures.
