Enhancing COVID-19 vaccine effectiveness evidence generation using tokenized immunization registries
The addition of state vaccine registries increased COVID-19 vaccine capture by 182% for primary wildtype series, 41% BA.4/5-adapted bivalent, and 38% XBB.1.5-adapted formulations. Tokenization of claims data to vaccine registries presents an opportunity for more accurate estimates of vaccine uptake and effectiveness than claims data alone.
