(Transdisciplinary Action Research Against Vaccine Esitancy)

"An action-research to encourage an active and participatory

citizenship capable of supporting public reflection on vaccines"

Project mission

Vaccine hesitancy is complex and context specific, varying across time, place and vaccines (MacDonald, 2015). Recently, misinformation on Coronavirus Disease 19 (COVID-19) vaccine safety and conflicting communications from experts and the media have generated concerns among the population for this reason TARAVH project aims to achieve the following objectives:

The project is characterized by three intertwined layers of research activities:

Relation of the project with the Horizon 2020/Horizon Europe themes and with the thematic priorities of PNR 2021-2027

The project deals with the Pillar II “Global Challenges & European Industrial Competitiveness”, Cluster 1 “Health” of Horizon Europe. In particular, it deals with the main aim of the cluster, that is improving and protecting the health and well-being of citizens of all ages by generating new knowledge and developing innovative solutions, with a focus of preventing diseases. Moreover, the project manifest complementarities with Cluster 2 “Culture, Creativity and Inclusive Society” in understanding and countering radicalisation and extremism, in building societal resilience to disinformation and fake news, and in developing responses to crises. Within the thematic priorities of PNR 2021-27, the project relates to the macro-issue “Health” and according to the PNR’s recommendations, the proposal addresses specifically to the public sector health institutions.

Our mission statement

A brief history

Vaccine hesitancy is on the rise, and it's a complex issue that can lead to outbreaks of preventable diseases and even deaths. But what's causing this phenomenon? Is it misinformation, conflicting messages from experts and the media, or something else entirely?

That's where our project comes in. We're tackling vaccine hesitancy with a three-layered approach, starting with the design and testing of a web-based observatory to monitor and assess vaccine hesitancy within local communities. We'll also be validating an Italian version of the 5C test, and studying the role of public health communication in a world of skepticism and distrust.

Using the Extended Parallel Process Model (EPPM), we'll investigate how health institutions can effectively communicate with the public about vaccines, especially in times of crisis like COVID-19. By crossing the psychological dimensions of the EPPM with our research findings, we'll provide insights on how to improve public health communication and manage effective social campaigns that address vaccine hesitancy.
