ABSTRACT Background Buruli ulcer is one of the most common mycobacterial diseases usually affecting poorer populations in tropical and subtropical environments. This disease, caused by M. ulcerans infection, has devastating effects for patients, with significant health and economic burden. Antibiotics are often used to treat affected individuals, but in most cases, surgery is necessary. Area covered We present progress on Buruli ulcer vaccines and identify knowledge gaps in this neglected tropical disease. Expert opinion The lack of appropriate infrastructure in endemic areas, as well as the severity of symptoms and lack of noninvasive treatment options, highlights the need for an effective vaccine to combat this disease. In terms of humoral immunity, it is vital to consider its significance and the magnitude to which it inhibits or slows down the progression of the disease. Only by answering these key questions will it be possible to tailor more appropriate vaccination and preventative provisions.
