John Green is an American bestselling young-adult novelist, and an advocate for global tuberculosis (TB) awareness and treatment access. In his latest book,“Everything is Tuberculosis”, he argues that TB continues to kill mainly by human choice.



Green is followed by a large community online with more than 2 million followers on Instagram and very successful YouTube channels (over 4 million followers for this channel vlogbrothers - YouTube). His followers are known as “TB fighters”, and Green himself was instrumental in the MSF Access Time For $5 campaign as well as the bedaquiline access campaign. Green is also a philanthropist and has a charity that supports work in the Philippines around TB. He has visited TB projects with other organizations before, and has just returned from our project in Tondo, Manila (end of October 2025)

Green will be the keynote speaker at this year’s The Union World Conference on Lung Health 2025, in Copenhagen, Denmark (November 18-21). MSF’s TACTiC project will also be present at the conference, aiming to raise the profile of paediatric TB. We will be presenting findings of an Epicentre operational research study on the implementation of new 2022 WHO treatment decision algorithms (guided scoring systems) for pulmonary TB in children under 10 years old. These guidelines provide important updates on how to improve the diagnosis, treatment and prevention of TB in children. If adopted and implemented, these guidelines could dramatically reduce the number of deaths due to TB amongst children. MSF is supporting the Manila Health Department to implement the new WHO guidelines in its active case finding TB project in Manila, Philippines –more specifically using shorter drug regimens and preventive treatment for children.
