Improving COVID vaccinations with Sentiment Analytics

California’s Office of Digital Innovation (ODI) informed COVID vaccine response by providing granular insights into sentiment around willingness and hesitancy for California’s Vaccinate All 58 campaign.

Customer Overview

ODI works with California state agencies and departments to use human centered design and technology to reimagine and redesign processes, systems, and services.

Gain insights into people’s attitudes, concerns, and needs

Build the digital infrastructure that leverages Calfornia’s vast digital footprint to:

  • Promote surveys to visitors to websites
  • Automate data collection, modeling, and analysis
  • Use Natural Language Processing to identify trending topics

Scaling Sentiment: Using digital surveys to target vaccines

ODI supported the state’s COVID vaccine response by leveraging digital surveys and applying advanced statistical methods to estimate vaccine hesitancy at the zip code level. These data were a critical component of the advertising strategy and directly informed allocation of the vaccine to zip codes with the highest likelihood of vaccine acceptance.

“California’s Office of Digital Innovation, in partnership with California Department of Public Health, California Office of Emergency Services, and other stakeholders, is driving an effort to promote vaccination , particularly among underserved communities.”
