Randomized trial assesses financial incentives for vaccine uptake in rural Ghana, suggesting effective strategies for improvement.

To evaluate the impact of financial incentives on COVID-19 vaccine uptake in rural Ghana.
Clustered randomized controlled trial conducted with 7,227 residents across six rural districts in Ghana.
Participants assigned to one of four treatment arms including cash incentives of $3 or $10, placebo, or standard health message.
Vaccination rates and intentions measured two months post-intervention, along with verification of vaccination status.
Participants in cash treatment arms had an average vaccination intention rate of 81% compared to 71% in the placebo group.
Verified vaccination rates showed 36.6% in the cash treatment group had at least one dose compared to 30.3% in the placebo group (P < 0.0001).
The low cash incentive ($3) produced a greater positive effect on vaccine uptake than the high incentive ($10).
