Vaccination is vital to protect the public against COVID-19. The aim of this systematic review identify and evaluate effectiveness interventions increase COVID-19 vaccine uptake. We searched a range databases (Embase, Medline, Psychology & Behavioral Science, PsycInfo, Web Science NIH Preprints Portfolio) from March 2020 July 2021 for studies which reported primary quantitative or qualitative research on Outcome measures included vaccination uptake intention vaccinate.

Communicating doctors’ consensus persistently increases COVID-19 vaccinations

Abstract The reluctance of people to get vaccinated represents a fundamental challenge containing the spread deadly infectious diseases 1,2 , including COVID-19. Identifying misperceptions that can fuel vaccine hesitancy and creating effective communication strategies overcome them are global public health priority 3–5 . Medical doctors trusted source advice about vaccinations 6 but media reports may create an inaccurate impression controversy is prevalent among doctors, even when broad consensus exists 7,8 Here we show views on COVID-19 vaccines widespread, correcting increases uptake. We implement survey 9,650 in Czech Republic find 90% trust vaccines. Next, respondents nationally representative sample ( n = 2,101) underestimate doctors’ trust; most common belief only 50% Finally, integrate randomized provision information true held by into longitudinal data collection regularly monitors vaccination status over 9 months. treatment recalibrates beliefs leads persistent increase approach demonstrated this paper shows how engagement professional medical associations, with their unparalleled capacity elicit individual large scale, help cheap, scalable intervention has lasting positive impacts behaviour.

Transmission of Vaccination Attitudes and Uptake Based on Social Contagion Theory: A Scoping Review

Vaccines, Journal Year: 2021, Volume and Issue: 9(6), P. 607 - 607

Published: June 5, 2021

Vaccine hesitancy is a complex health problem, with various factors involved including the influence of an individual’s network. According to Social Contagion Theory, attitudes and behaviours individual can be contagious others in their social networks. This scoping review aims collate evidence on how vaccination uptake are spread within Databases PubMed, PsycINFO, Embase, Scopus were searched full text 24 studies being screened. A narrative synthesis approach was used interpret findings. Eleven cross-sectional included. Participants held more positive greater likelihood get vaccinated or vaccinate child when they frequently exposed discussing vaccinations family friends. We also observed that decreased friends hesitant take vaccine. Homophily—the tendency similar individuals connected network—was identified as significant factor drives results, especially respect race ethnicity. highlights key role networks play shaping uptake.

The understanding of the public response to COVID-19 vaccines is key success factor control pandemic. To understand response, there a need explore opinion. Traditional surveys are expensive and time-consuming, address limited health topics, obtain small-scale data. Twitter can provide great opportunity opinion regarding vaccines. current study proposes an approach using computational human coding methods collect analyze large number tweets wider perspective on vaccine. This identifies sentiment machine learning rule-based approach, discovers major explores temporal trend compares topics negative non-negative statistical tests, discloses top having sentiment. Our findings show that vaccine had decreasing between November 2020 February 2021. We found users have discussed wide range from vaccination sites U.S. election was significant difference weight most topics. results also indicate different topic priorities focuses. research illustrates data be used

The influence of social norms varies with “others” groups: Evidence from COVID-19 vaccination intentions

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(29)

The theory that health behaviors spread through social groups implies efforts to control COVID-19 vaccination will succeed if people believe others in their are getting vaccinated. But “others” can refer many groups, including one’s family, neighbors, fellow city or state dwellers, copartisans. One challenge examining these understudied distinctions is factors may confound observed relationships between perceived norms (what do) and intended themselves do), as there plausible common causes for both. We address issues using survey data collected the United States during late fall 2020 ( n = 824) spring 2021 996) a matched design approximates pair-randomized experiments. find strong relationship intentions when controlling real risk (e.g., age), well dimensions known predict preventive trust scientists). strength of declines queried group grows larger more heterogeneous. copartisans second magnitude family friends among Republicans but undetectable Democrats. Sensitivity analysis shows could be explained away only by an unmeasured variable with large effects (odds ratios 2 15) on perceptions intentions.

Video-based messages to reduce COVID-19 vaccine hesitancy and nudge vaccination intentions

PLoS ONE, Journal Year: 2022, Volume and Issue: 17(4), P. e0265736 - e0265736

Published: April 6, 2022

Vaccines are highly effective for curbing the spread of SARS-CoV-2 (COVID-19). Yet, millions Americans remain hesitant about getting vaccinated, jeopardizing our ability to end COVID-19 pandemic by fueling and development new variants. We show that brief video-based messages encouragement addressing specific vaccine concerns increase vaccination intentions, in turn, predictive future uptake. Results from online experiment reveal willingness get vaccinated is driven confidence vaccines perceived behavioral control vaccinated. Importantly, were particularly among more skeptical populations including people who identify as politically conservative or moderate those express low trust government institutions. Our findings corroborate real-world significance devise how even short, scalable can provide governments health authorities an inexpensive, yet tool increasing intentions vaccinate against most reluctant them.

Public health organizations increasingly use social media advertising campaigns in pursuit of public goals. In this paper, we evaluate the impact about $40 million advertisements that were run and experimentally tested on Facebook Instagram, aimed at increasing COVID-19 vaccination rates first year vaccine roll-out. The 819 randomized experiments our sample by 174 different collectively reached 2.1 billion individuals 15 languages. We find these are, average, effective influencing self-reported beliefs—shifting opinions close to 1% baseline with a cost per influenced person $3.41. Combining result an estimate relationship between survey outcomes derived from observational data yields estimated additional $5.68. There is further evidence are especially users’ knowledge how get vaccines. Our results represent, best knowledge, largest set online interventions analyzed date.

Nudges for COVID-19 voluntary vaccination: How to explain peer information?

Social Science & Medicine, Journal Year: 2021, Volume and Issue: 292, P. 114561 - 114561

Published: Nov. 9, 2021

Vaccination promotion is a crucial strategy to end the COVID-19 pandemic; however, individual autonomy should also be respected. This study aimed discover other-regarding information nudges that can reinforce people's intention receive vaccine without impeding their autonomous decision-making. In March 2021, we conducted an online experiment with 1595 people living throughout Japan, and randomly assigned them either of one control group three treatment groups received messages differently describing peer information: control, comparison, influence-gain, influence-loss. We compared each message's effects on vaccination intention, decision-making, emotional response. found influence-gain nudge was effective in increasing number older adults who newly decided vaccine. The comparison influence-loss further reinforced had already planned it. However, nudge, which conveys similar but loss-framing, increased viewers' negative emotion. These no promoting effect for young lower intentions at baseline. Based findings, propose governments use different depending purposes targets, such as instead influence-loss, encourage voluntary behavior.
