Can financial incentives and other nudges increase COVID-19 vaccinations among the vaccine hesitant? A randomized trial

Vaccine, Journal Year: 2022, Volume and Issue: 40(43), P. 6235 - 6242

Despite rapid initial uptake, COVID-19 vaccinations in the United States stalled within a few months of widespread rollout 2021. In response, many state and local governments, employers health systems used public messaging, financial incentives creative scheduling tools to increase vaccine uptake. Although these approaches drew on evidence from influenza other vaccination efforts, they were largely untested context SARS-CoV-2. mid-2021, after vaccines widely available, we evaluated intentions uptake using randomized control trial. To do this, recruited unvaccinated members Medicaid managed care plan California (n = 2,701) randomly assigned them different messages, $10 or $50 for vaccination, simple appointment scheduler, control. While messages increased intentions, none interventions rates. Estimates rule out even relatively small increases Small behavioral nudges not meaningfully rates amongst hesitant.

Financial incentives for vaccination do not have negative unintended consequences

Abstract Financial incentives to encourage healthy and prosocial behaviours often trigger initial behavioural change 1–11 , but a large academic literature warns against using them 12–16 . Critics warn that financial can crowd out motivations reduce perceived safety trust, thereby reducing when no payments are offered eroding morals more generally 17–24 Here we report findings from large-scale, pre-registered study in Sweden causally measures the unintended consequences of offering for taking first dose COVID-19 vaccine. We use unique combination random exposure incentives, population-wide administrative vaccination records rich survey data. find negative incentives; reject even small impacts on future uptake, morals, trust safety. In complementary study, informing US residents about existence state incentive programmes also has consequences. Our inform not only debate behaviour policy-makers who consider behaviour.

Last-mile delivery increases vaccine uptake in Sierra Leone

Nature, Journal Year: 2024, Volume and Issue: 627(8004), P. 612 - 619

Abstract Less than 30% of people in Africa received a dose the COVID-19 vaccine even 18 months after development 1 . Here, motivated by observation that residents remote, rural areas Sierra Leone faced severe access difficulties 2 , we conducted an intervention with last-mile delivery doses and health professionals to most inaccessible areas, along community mobilization. A cluster randomized controlled trial 150 communities showed this mobile vaccination teams increased immunization rate about 26 percentage points within 48–72 h. Moreover, auxiliary populations visited our points, which more doubled number inoculations administered. The additional vaccinated per site translated implementation cost US $33 person vaccinated. Transportation reach remote villages accounted for large share total costs. Therefore, bundling multiple maternal child interventions same visit would further reduce costs treated.

Field testing the transferability of behavioural science knowledge on promoting vaccinations

Nature Human Behaviour, Journal Year: 2024, Volume and Issue: 8(5), P. 878 - 890

Published: March 14, 2024

As behavioural science is increasingly adopted by organizations, there a growing need to assess the robustness and transferability of empirical findings. Here, we investigate insights from various sources knowledge field settings. Across three pre-registered randomized controlled trials (RCTs, N = 314,824) involving critical policy domain-COVID-19 booster uptake-we tested text-based interventions that either increased vaccinations in prior work (RCT1, NCT05586204), elevated vaccination intentions an online study (RCT2, NCT05586178) or were favoured scientists non-experts (RCT3, NCT05586165).

Evaluating expectations from social and behavioral science about COVID-19 and lessons for the next pandemic

Published: Oct. 10, 2022

Social and behavioral science research proliferated during the COVID-19 pandemic, reflecting substantial increase in influence of public health policy more broadly. This review presents a comprehensive assessment 742 scientific articles on human behavior COVID-19. Two independent teams evaluated 19 substantive recommendations (“claims”) potentially critical aspects behaviors pandemic drawn from most widely cited papers Teams were made up original authors an team, all whom blinded to other team member reviews throughout. Both found evidence support 16 claims; for two claims, only null evidence; no claims did find effects opposite direction. One claim had available assess. Seemingly due risks studies limited surveys, highlighting need investment field validation studies. The strongest findings indicate interventions that combat misinformation polarization, utilize effective forms messaging engage trusted leaders emphasize positive social norms.

Addressing vaccine hesitancy using local ambassadors: A randomized controlled trial in Indonesia

European Economic Review, Journal Year: 2024, Volume and Issue: 163, P. 104683 - 104683

Published: Jan. 23, 2024

In settings where resistance and rampant misinformation against vaccines exist, the prospect of containing infectious diseases remains a challenge. Can delivery information regarding benefits vaccination through personal home visits by local ambassadors increase vaccine uptake? We conduct door-to-door randomized campaign targeted towards COVID-19 unvaccinated individuals in rural Indonesia. recruited from villages tasked to deliver about promote one-on-one meetings, using an interpersonal behavioral change communication approach. To investigate which type ambassador—health cadres, influential individuals, laypersons—is most effective, we randomly vary ambassador that delivers at village level. find overall take-up is quite moderate there are no differences outcomes across treatment groups. These results highlight challenge boosting uptake late stages pandemic.

Effectiveness of patient reminders on influenza vaccination coverage among adults with chronic conditions: A feasibility study in Australian general practices

Preventive Medicine, Journal Year: 2024, Volume and Issue: 184, P. 107983 - 107983

Influenza vaccination is recommended for Australians 18+ years old with medical risk factors, but coverage suboptimal. We aimed to examine whether automatic, opportunistic patient reminders (SMS and/or printed) before appointments a general practitioner increased influenza uptake. This clustered non-randomised feasibility study in Australian practice included patients aged 18–64 at least one factor attending participating practices between May and September 2021. Software installed intervention identified unvaccinated eligible when they booked an appointment, sent on booking 1 h appointments), printed automatic arrival. Control provided usual care. Clustered analyses adjusted sociodemographic differences among were performed using logistic regression. A total of 12,786 at-risk adults attended 16 (received = 4066; 'internal control' receiving care 8720), 5082 individuals eight control practices. Baseline uptake (2020) was similar (~34%). After the intervention, all groups (control 29.3%; internal 30.0%; 31.6% (p-value 0.203). However, SMS (39.3%, OR 1.65; 95%CI 1.20;2.27; number necessary treat 13), especially combined other reminder forms.
