The effect of mandatory COVID-19 certificates on vaccine uptake: synthetic-control modelling of six countries

Melinda C. Mills et al.

Summary: Mandatory COVID-19 certification can increase vaccine uptake, especially in countries with lower uptake rates. The increase in vaccinations starts before implementation and lasts for about 40 days. The effect is most pronounced in individuals younger than 30 years old. Access restrictions in certain settings are associated with increased uptake among those younger than 20 years old.

Do people reduce compliance with COVID-19 guidelines following vaccination? A longitudinal analysis of matched UK adults

Liam Wright et al.

Summary: The study found that compliance with COVID-19 guidelines generally increased between October 2020 and March 2021 in the UK, regardless of vaccination status or month of vaccination. There was no clear evidence that vaccinated individuals decreased compliance relative to those who were not yet vaccinated. Continued monitoring is necessary as vaccination efforts progress and public health measures evolve.

The Vaccination Concerns in COVID-19 Scale (VaCCS): Development and validation

Kyra Hamilton et al.

Summary: This study developed and validated the Vaccination Concerns in COVID-19 Scale (VaCCS), a comprehensive measure of beliefs and concerns regarding COVID-19 vaccines. The scale consists of 35 items with 8 subscales and showed good fit with the data in different samples. The VaCCS demonstrated concurrent and predictive validity, and can be used by researchers and practitioners to assess vaccine intentions and outcomes.

The Effectiveness of Interventions for Increasing COVID-19 Vaccine Uptake: A Systematic Review

Eleonore Batteux et al.

Summary: Vaccination is crucial in protecting the public from COVID-19. This systematic review aims to identify and evaluate the effectiveness of interventions to increase COVID-19 vaccine uptake. Personalized communication and text message reminders for appointments were found to be effective in increasing vaccine uptake, while the results on vaccination intention were mixed.

Effectiveness of message framing in changing COVID-19 vaccination intentions: Moderating role of travel desire

Dogan Gursoy et al.

Summary: This research examines the effectiveness of message framing, message appeal, and information content on changing individuals' COVID-19 vaccination intentions. The findings suggest that loss-framed messages are more effective in reducing risk perceptions and changing vaccination intentions. Additionally, travel desire moderates the relationship between vaccine risk perceptions and vaccination intentions.

Reactance revisited: Consequences of mandatory and scarce vaccination in the case of COVID-19

Philipp Sprengholz et al.

Summary: Psychological reactance theory posits that the restriction of valued behaviors leads to anger and negative cognitions, motivating actions to regain the limited freedom. Studies found that reactance was stronger when vaccination intentions were low and a mandate was introduced, or when vaccination intentions were high and vaccines were scarce, increasing intentions to take actions against the restriction. This information can assist policymakers in controlling the spread of infectious diseases like COVID-19.

Modification of a vaccine hesitancy scale for use in adult vaccinations in the United States and China

Kaitlyn B. Akel et al.

Behavioural responses to Covid-19 health certification: a rapid review

John Drury et al.

Summary: Public attitudes towards health certificates are generally positive for international travel but negative for work and other activities. There is evidence that mandatory vaccinations may lead to vaccine hesitancy. Additionally, restricting access to settings and activities to those with antibody test certificates may result in intentional exposure to infection for some individuals.

Vaccine Passports May Backfire: Findings from a Cross-Sectional Study in the UK and Israel on Willingness to Get Vaccinated against COVID-19

Talya Porat et al.

In Israel, a country with vaccine passports, people reported greater autonomy frustration compared to the UK, a country without vaccine passports.

The potential impact of vaccine passports on inclination to accept COVID-19 vaccinations in the United Kingdom: Evidence from a large cross-sectional survey and modeling study

Alexandre de Figueiredo et al.

Summary: The UK Government is considering the introduction of vaccine passports for domestic use and international travel to facilitate the vaccination rate. A national survey of 17,611 adults in the UK from April 9 to 27, 2021, found that while some respondents would be more inclined to vaccinate with vaccine passports, the overall impact might actually decrease the willingness to accept COVID-19 vaccines, especially if passports were required for domestic use. Factors like gender, education level, and religion were found to influence the inclination to vaccinate with the introduction of vaccine passports.
