New Vaccines

Rapid, large-scale uptake of new vaccines against COVID-19 will be crucial to decrease infections and end the pandemic. In a recent article in this journal, Julian Savulescu argued in favour of monetary incentives to convince more people to be vaccinated once the vaccine becomes available. To evaluate the potential of his suggestion, we conducted an experiment investigating the impact of payments and the communication of individual and prosocial benefits of high vaccination rates on vaccination intentions. Our results revealed that none of these interventions or their combinations increased willingness to be vaccinated shortly after a vaccine becomes available. Consequently, decision makers should be cautious about introducing monetary incentives and instead focus on interventions that increase confidence in vaccine safety first, as this has shown to be an especially important factor regarding the demand for the new COVID-19 vaccines.

The Impact

The rapid development of COVID-19 vaccines is a tremendous scientific response to the current global pandemic. However, vaccines per se do not save lives and restart economies. Their success depends on the number of people getting vaccinated. We used a survey experiment to examine the impact on vaccine intentions of a variety of public health messages identified as particularly promising: three messages that emphasize different benefits from the vaccines (personal health, the health of others, and the recovery of local and national economies) and one message that emphasizes vaccine safety. Because people will likely be exposed to multiple messages in the real world, we also examined the effect of these messages in combination. Based on a nationally quota representative sample of 3,048 adults in the United States, our findings suggest that several forms of public messages can increase vaccine intentions, but messaging that emphasizes personal health benefits had the largest impact.

The Impact

Population confinements have been one of the most widely adopted non-pharmaceutical interventions (NPIs) implemented by governments across the globe to help contain the spread of the SARS-CoV-2 virus. While confinement measures have been proven to be effective to reduce the number of infections, they entail significant economic and social costs. Thus, different policy makers and social groups have exhibited varying levels of acceptance of this type of measures. In this context, understanding the factors that determine the willingness of individuals to be confined during a pandemic is of paramount importance, particularly, to policy and decision-makers. In this paper, we study the factors that influence the unwillingness to be confined during the COVID-19 pandemic by means of a large-scale, online population survey deployed in Spain. We apply both quantitative (logistic regression) and qualitative (automatic pattern discovery) methods and consider socio-demographic, economic and psychological factors, together with the 14-day cumulative incidence per 100,000 inhabitants. Our analysis of 109,515 answers to the survey covers data spanning over a 5-month time period to shed light on the impact of the passage of time. We find evidence of pandemic fatigue as the percentage of those who report an unwillingness to be in confinement increases over time; we identify significant gender differences, with women being generally less likely than men to be able to sustain long-term confinement of at least 6 months; we uncover that the psychological impact was the most important factor to determine the willingness to be in confinement at the beginning of the pandemic, to be replaced by the economic impact as the most important variable towards the end of our period of study. Our results highlight the need to design gender and age specific public policies, to implement psychological and economic support programs and to address the evident pandemic fatigue as the success of potential future confinements will depend on the population's willingness to comply with them.

The Impact

This article provides experimental evidence of the impact of a four-year inter-vention aimed at developing students’ growth mindset and internal locus ofcontrol in disadvantaged middle schools. We find a 0.07 standard deviationincrease in GPA, associated with a change in students’ mindset, improved be-havior as reported by teachers and school registers, and higher educational andprofessional aspirations. International empirical benchmarks reveal that theintervention is at least ten times more cost-effective than the typical educa-tional intervention. However, while reducing between-school inequality whentargeted to disadvantaged schools, the program benefits less to more fragilestudents, therefore increasing within-school inequality.

Evidence Based Decision Making

Abstract Objectives The use of evidence on program performance and potential for impact for decision making in food fortification programs is limited and often done in isolation from other micronutrient interventions. We present a framework for fortification stakeholders responsible for making program recommendations and decisions to facilitate and document evidence-based decision making. Methods First, we reviewed the literature to define the key decision makers and decisions necessary for effective fortification program design and delivery, informed by a clear impact pathway. Then we classified decisions by domain, identified data sources and criteria for their assessment, and adapted the GRADE Evidence to Decision framework to summarize the results. Finally, we considered how the framework would apply to different country programs to test its utility. Results Policymakers, particularly government ministries, and the food producers themselves are the most important decision makers in a fortification program, while technical support agencies, donor agencies, and the research community play important roles in translating data and evidence into contextualized recommendations that meet the needs of different decision makers. The main fortification decision types were classified into five domains across the impact pathway: 1) program design (need, food vehicle(s)); 2) program delivery (compliance, quality, coverage); 3) program impact (nutrient intake and status); 4) overlapping micronutrient interventions and/or under-served populations; and 5) decisions to continue or stop programs. Important criteria for the assessment of each decision type included priority, benefits/risks, equity, acceptability, and feasibility among others. Country examples illustrated the importance of coordinating decision-making in the context of overlapping micronutrient interventions to ensure continued safety and impact over time. Conclusions This framework is a practical tool to enable evidence-based decision making by fortification stakeholders. Using evidence in a systematic and transparent way can enable more effective program design, delivery, and ultimately health impacts. Funding Sources Bill & Melinda Gates Foundation.

During the COVID-19 pandemic, authorities must decide which groups to prioritise for vaccination. These decision will occur in a constantly shifting social-epidemiological landscape where the success of large-scale non-pharmaceutical interventions (NPIs) like physical distancing requires broad population acceptance. We developed a coupled social-epidemiological model of SARS-CoV-2 transmission. Schools and workplaces are closed and re-opened based on reported cases. We used evolutionary game theory and mobility data to model individual adherence to NPIs. We explored the impact of vaccinating 60+ year-olds first; <20 year-olds first; uniformly by age; and a novel contact-based strategy. The last three strategies interrupt transmission while the first targets a vulnerable group. Vaccination rates ranged from 0.5% to 4.5% of the population per week, beginning in January or July 2021. Case notifications, NPI adherence, and lockdown periods undergo successive waves during the simulated pandemic. Vaccination reduces median deaths by 32%-77% (22%-63%) for January (July) availability, depending on the scenario. Vaccinating 60+ year-olds first prevents more deaths (up to 8% more) than transmission-interrupting strategies for January vaccine availability across most parameter regimes. In contrast, transmission-interrupting strategies prevent up to 33% more deaths than vaccinating 60+ year-olds first for July availability, due to higher levels of natural immunity by that time. Sensitivity analysis supports the findings. Further research is urgently needed to determine which populations can benefit from using SARS-CoV-2 vaccines to interrupt transmission.

Do skilled decision-makers plan further into the future than novices? This question has been investigated for almost 75 years, traditionally by studying expert players in complex board games like chess. However, the complexity of these games poses a barrier to detailed modeling of human behavior. Conversely, common planning tasks in cognitive science are often lower-complexity and impose a ceiling for the depth to which any player can plan. Here, we investigate expertise by studying decision-making in a board game which is at the limit of complexity that can be precisely modeled using state-of-the-art statistical techniques, and which has ample opportunity for skilled players to plan deeply. We find robust evidence for increased planning depth with expertise in both laboratory and large-scale naturalistic data.

Abstract Background Effective prevention of HPV is possible, but &lt; 50% of adolescents in the Midwest complete the recommended vaccine series. Strategies to increase HPV vaccination rates have demonstrated efficacy, however widespread implementation of these interventions has not been realized. Behavioral nudges have demonstrated efficacy in increasing uptake of desired heath behaviors among providers (e.g. hand hygiene, judicious antibiotic prescribing). This trial assessed the impact of an assessment and feedback, communication training, and behavioral nudge (i.e. poster-sized vaccine commitment statements) intervention (T3) on adolescent vaccination rates and parental satisfaction at four Midwestern pediatric practices. Methods Practices were randomly assigned to receive either 1) assessment and feedback or 2) T3 intervention. Providers (n=16) completed surveys regarding vaccine polices and parents of vaccine eligible adolescents (n=230) reported their child’s vaccine history and satisfaction with the consultation. Practice- level vaccination rates for Tdap, Meningococcal, and HPV were calculated through billing data queries from an integrated pediatric health network. Vaccination rates and provider/ parental responses were compared by intervention arm. Results All practices evidenced increased adolescent vaccine rates, ranging from 0.8% to 3.4% for Meningococcal and 1.3% to 12.1% for Tdap. Three of the four practices had increased HPV vaccination rates (1% to 10%), however there was no statistically significant difference by study arm. Most parents (M age 41.34; SD 8.05; 85% female, 68% White) indicated their child had previously initiated the HPV vaccine series (61%) and 72% indicated receipt of an HPV vaccine during the study visit. Concerns among HPV vaccine hesitant parents (n=60) included concerns about vaccine safety and necessity. Most (97%) of parents were satisfied with their consultation. Conclusion Practices in both intervention groups evidenced an increase in adolescent vaccination rates. While some parents had concerns about HPV vaccine safety and necessity, parents welcomed discussions about HPV vaccine and were satisfied with their provider’s communication regardless of their vaccine decisions.
