Determinants of undervaccination of routine childhood immunization in Argentina: A cross-sectional study.

Routine childhood immunization is one of the most effective methods of preventing infectious diseases in children. In Argentina, there has been a decline in routine immunization coverage since 2015, with very little evidence to date on underlying drivers of this steady decline. We administered an online nationwide behavioral insights survey in Argentina between July 1-25, 2022, targeting parents with at least one child under the age of 12 years.

Informing social media analysis for public health: a cross-sectional survey of professionals.

Background: During the COVID-19 pandemic, the field of infodemic management has grown in response to urgent global need. Social listening is the first step in managing the infodemic, and many organizations and health systems have implemented processes. Social media analysis tools have traditionally been developed for commercial purposes, rather than public health, and little is known of the experiences and needs of those professionals using them for infodemic management.

Co-Designing a Mobile-Based Game to Improve Misinformation Resistance and Vaccine Knowledge in Uganda, Kenya, and Rwanda.

Misinformation can decrease public confidence in vaccines, and reduce vaccination intent and uptake. One strategy for countering these negative impacts comes from inoculation theory. Similar to biological vaccination, inoculation theory posits that exposure to a weakened form of misinformation can develop cognitive immunity, reducing the likelihood of being misled.

Persuasive COVID-19 vaccination campaigns on Facebook and nationwide vaccination coverage in Ukraine, India, and Pakistan.

Social media platforms have a wide and influential reach, and as such provide an opportunity to increase vaccine uptake. To date, there is no large-scale, robust evidence on the offline effects of online messaging campaigns. We aimed to test whether pre-tested, persuasive messaging campaigns from UNICEF, disseminated on Facebook, influenced COVID-19 vaccine uptake in Ukraine, India, and Pakistan.

Empowering Health Workers to Build Public Trust in Vaccination: Experience from the International Pediatric Association's Online Vaccine Trust Course, 2020-2021.

Background: The quality of interactions between health workers (HWs) and caregivers is key in vaccine acceptance. To optimize this, HWs need knowledge about best vaccine communication practices in person and on social media. Most pre-service curricula do not include such approaches.

Exploring public perceptions of vaccine-derived poliovirus and a novel oral polio vaccine in the Democratic Republic of the Congo, Kenya, and Nigeria.

Background: The Global Polio Eradication Initiative introduced novel oral polio vaccine Type 2 (nOPV2) to address circulating vaccine-derived poliovirus Type 2 (cVDPV2). Although nOPV2 is a more genetically stable vaccine, it may not have the immediate trust of communities and health workers due to its novelty, potential side effects, and introduction under an Emergency Use Listing (EUL). We explored how nOPV2 introduction might be perceived by stakeholders and identified communications barriers related to nOPV2 hesitancy.

Social Listening in Eastern and Southern Africa, a UNICEF Risk Communication and Community Engagement Strategy to Address the COVID-19 Infodemic.

The coronavirus disease 2019 (COVID-19) pandemic has been closely tied with what has been called an infodemic, a "second disease" that occurs when massive information volumes (particularly with a high prevalence of false information) hinder the public health response. In this context, social listening, the process of monitoring and analyzing conversations to inform strategic activities both online and offline, becomes an even more essential component of risk communication and engagement strategies. In the Eastern and Southern Africa region, the United Nations Children's Fund (UNICEF) and partners in the response have activated their capacity to gather insights on the information needs of the populations served to better inform and engage with local communities.
