Crowdsourcing interventions to promote uptake of COVID-19 booster vaccines

A call for immediate action to increase COVID-19 vaccination uptake to prepare for the third pandemic winter

“…A crowd-sourcing study made use of many health experts and explored a large number of possible interventions to increase booster vaccine uptake 13 . Two of the five interventions rated as both effective and acceptable by experts and members of the general public related to health-care personnel engagement—mobile vaccination teams and promotional campaigns.…”

“…Research shows that receiving invitations to appointments 19 – 21 , links via text messages for appointment booking 16 and text message reminders before regular appointments 22 leads to increased uptake. Mobile vaccination teams can help facilitate access 13 , and mandatory regulations may be appropriate under certain conditions 23 . Generally, making vaccination an easy choice for everyone should be the goal 24 .…”

Loss-framing of information and pre-vaccination consultation improve COVID-19 vaccine acceptance: A survey experiment

“…Nevertheless, there are still various policy and intervention options to be considered for vaccination promotion, while there was limited evidence for them. In systematic reviews, it was summarized that there are different types of interventions for promoting COVID-19 vaccines, including communication (education/persuasion/psychological enablement), modeling (providing examples for imitation), environmental restructuring (changing context for vaccination), financial incentivization, restriction, and sanction (punishment) (21)(22)(23). The influence of modeling (influence of acquaintances), environmental restructuring (convenience of vaccination venues) and restrictions (different quarantine measures for vaccinated and unvaccinated people) were examined in a prior discrete choice study in Hong Kong (19), while the other factors were not tested in the local context.…”

“…The influence of modeling (influence of acquaintances), environmental restructuring (convenience of vaccination venues) and restrictions (different quarantine measures for vaccinated and unvaccinated people) were examined in a prior discrete choice study in Hong Kong ( 19 ), while the other factors were not tested in the local context. Among them, sanction or punishment for unvaccinated people were considered less acceptable by the public, and likely to cause social and psychological side effects and increase inequalities in health ( 22 ), so this was not considered in our study. Strategies related to communications and financial incentivization were, however, further tested in this study.…”

“…Strategies related to communications and financial incentivization were, however, further tested in this study. Among communication strategies, healthcare professional consultation or recommendation serves as a way to improve vaccination through persuasion, assessment of safety of vaccination and potential risk of infection for vaccination, and information framing is a typical psychological enablement method in promotion of vaccination and other health prevention measures ( 22 , 24 ). On the other hand, provision of cash for vaccinated individuals is a common way to financially incentivize people to receive the vaccine ( 23 ).…”
