Challenge { Vaccination hesitancy }

How to rethink and answer vaccination hesitancy in the era of fake news and social media?

According to the World Health Organization (WHO), immunization is undoubtedly one of the most effective and cost-effective interventions to protect oneself and others from infectious diseases (1). It has eradicated smallpox and now prevents 2 to 3 million deaths per year from diseases such as measles, diphtheria, pertussis, pneumonia, poliomyelitis, cervical cancer, hepatitis B, rotavirus diarrhea, rubella and tetanus (2). As an essential component of the fundamental right to health, vaccination is a primary healthcare intervention for which responsibility is shared by individuals, groups and governments (3).

However, while the benefits of immunization are available to an increasing number of individuals, large gaps in coverage persist, not only between countries but also within their territories (1). Indeed, 1.5 million deaths per year worldwide are attributable to vaccine-preventable diseases (2).

Today, social networks as a communication medium and interaction platform are one of the main sources of information for individuals. They participate in the relay of misinformation and feed an increasing vaccination hesitancy (4). This phenomenon, which has existed since the creation of vaccines (7), is defined as a delay in the acceptance of a vaccine or its refusal, despite the availability of vaccination services. It is complex, context specific and varies over time, depending on the location and the vaccines (8). In France, waves of vaccine hesitation have been observed since the A (H1N1) influenza pandemic (9). In 2016, France was the European country with the highest level of vaccine mistrust (10).

Vaccine-preventable diseases are now on the rise in France and around the world (4), alarming the World Health Organization (WHO), regional and local stakeholders (1). In France, Agnes Buzyn, Minister of Solidarity and Health, has made this issue a priority (11).

By launching this challenge, JOGL joins the ongoing global dynamic and efforts to address the contemporary challenges of vaccination by proposing an inclusive and collaborative approach to rethink and answer vaccination hesitancy in the contemporary era.

Participations are open from the 14th of September 2019 until the 1st of December 2019. Start now!

To participate in a challenge, just click on the “participate” button at the top of the page.

- You can go explore projects and see if you can contribute to any of them. By contributing to projects that have been submitted to a challenge, you automatically participate in the challenge.

- You can submit your own project. To do so, either choose a project you have already created or create a new project and come back on the challenge page to submit it. 

Participation is entirely free and open but some conditions need to be met. Check out the rules of participations for more information.


Participating in this challenge, means contributing to developing open source solutions to improve the health of populations around the world. It also means being part of a collaborative and innovative initiative, working for the greater good


You already have a project?

This is an opportunity to find collaborators and visibility you might need to advance your goals and broaden your impact. It is also an occasion to share the needs and priorities you might have identified so that other participants can help you tackle them.


You don’t have a project (yet)?


You are a student: this initiative will allow you to acquire experience by applying the knowledge and skills you are learning to projects led by experts with needs. You can even easily start your own project! 


You are a professional: you can find in those projects and challenges the excitement of playing an important role by helping teams develop projects that might concretely change the lives of people around the world. You can also be part of the discovery of projects by evaluating them!


You are a citizen: this is the occasion for you to become an actor of research. You might be interested or passionate about it, you might be unaware or you might even mistrust it. This is the chance for you to see what happens from the inside and make a difference alongside experts! 


Get rewarded!

In programs, all contributions will be reviewed by a pool of experts and rewarded during a special Award Ceremony by the renowned members of our Committee for Science, Ethics and Impact. This is a great opportunity to get official recognition for your work and impact.



Awarded by the Committee for Ethics, Science and Impact (CESI) on the 18th of December, prizes are based on the grades and comments from independent evaluators.

The criterias are co-elaborated by JOGL and the CESI and validated by the CESI.

The projects are first ranked based on the evaluation made by independant evaluator during the first two weeks of December. The CESI then examines comments and takes them into account to decide on the final ranking.

The best projects of the challenge win, as ranked by the CESI.

One JOGL Community prize

Awarded by JOGL on the 18th of December, the JOGL Community prize is based on the numbers of claps on the project page. Only the most claped project wins.

One Grand Prize

Awarded by the Committee for Ethics, Science and Impact the Grand Prize is attributed to one project based on the result of a vote by the members of the CESI on the 18th of December 2019 (independantly form the evaluations).


Awarded to indivudals and project by JOGL on the 18th of December, medals are based on the datas from the platform (number of claps, comments, needs answered, ...).
