Abstract:
From 2019 to 2023, a total of 30.8602 million doses of non-National Immunization Program (non-NIP) vaccines were administered in Shaanxi Province, averaging 1 561 doses per 10 000 population. The annual administration of non-NIP vaccines increased from 4.359 1 million doses in 2019 to 7.858 2 million doses in 2023, with their proportional representation among all vaccines rising from 30.82% to 55.15%( χ2 trend=2 440 581.54, P<0.001). The administration rate per 10 000 population increased from 1 105 doses to 1 986 doses during this period( χ2 trend=373.10, P<0.001). Concurrently, the substitution rate of non-NIP vaccines for National Immunization Program vaccines rose from 4.94% in 2019 to 16.11% in 2023.
