Financial incentives and COVID-19 vaccinations: Evidence from a conditional cash transfer program

Area of Science:

• Public Health
• Health Economics
• Epidemiology

Background:

• The COVID-19 pandemic highlighted challenges in achieving high vaccination rates.
• Slovakia faced hospital overcrowding due to insufficient vaccine uptake.
• Targeted interventions were necessary to encourage vaccination among vulnerable populations.

Purpose of the Study:

• To evaluate the effectiveness of a nationwide conditional cash transfer program in increasing COVID-19 vaccine uptake among individuals aged 60 and older in Slovakia.
• To assess the cost-benefit analysis of the implemented financial incentive program.

Main Methods:

• The study utilized a quasi-experimental design, leveraging the age eligibility threshold for the cash transfer as a natural experiment.
• Regression discontinuity design was employed to estimate the causal effect of the program on vaccination rates.
• Economic analysis was performed to compare intervention costs with associated benefits.

Main Results:

• The conditional cash transfer program led to a statistically significant increase in COVID-19 vaccination rates within the eligible age group.
• The intervention demonstrated a positive impact on public health outcomes by enhancing vaccine coverage.
• Preliminary cost-benefit analysis indicated that the program's benefits likely exceeded its financial costs.

Conclusions:

• Conditional cash transfer programs can be an effective tool for increasing vaccine uptake in public health emergencies.
• The Slovakian experience provides valuable insights into the design and implementation of incentive-based health policies.
• Further research should explore long-term impacts and scalability of such interventions.
