### Summary
- Quick vaccine rollouts are crucial for a strong economic recovery, but vaccine hesitancy could prolong the pandemic and the need for social distancing and lockdowns.
- Individual-level data from nationally representative surveys developed by YouGov and Imperial College London are used to empirically examine determinants of vaccine hesitancy across 17 countries and over time.
- Vaccine hesitancy is introduced into an extended SIR model to assess its impact on pandemic dynamics.

### Key empirical findings
- Vaccine demand depends on demographic features:
  - Age
  - Gender
- Vaccine demand also depends on perceptions and behavioral factors:
  - Perceptions about the severity of COVID-19
  - Perceptions about side effects of the vaccine
  - Vaccine access
  - Compliance with protective behaviors
  - Overall trust in government
  - How information is shared with peers

### Model results and scenarios
- Introducing vaccine hesitancy into an extended SIR model yields two key scenario outcomes:
  - If hesitancy slows down vaccine rollouts, hesitancy can increase COVID-19 infections and deaths significantly.
  - If all willing adults can be immunized rapidly, hesitancy has a smaller impact on pandemic outcomes.
