This invention relates to the field of medical information management technology, specifically to an intelligent verification method and system for vaccine administration processes. In this invention, isolated operation logs during the vaccination process are reconstructed into a complete sequence of recipient vaccination behaviors based on their inherent temporal correlation and the homology of the executing entities. A Hidden Markov Model is then used to perform in-depth analysis of this sequence, inferring the underlying vaccination stage states that conform to clinical logic from the observed specific behaviors. This elevates verification from static data checking to a dynamic process review. Furthermore, the inferred actual stage sequence is rigorously compared with the standardized process in three dimensions: stage completeness, sequential accuracy, and dose interval. Innovatively, a probability confidence level is calculated for any identified process deviations, achieving a quantitative assessment of abnormal behavior.
