Abstract
The One Health (OH) approach describes the interconnection between the health of animals, humans, and the environment. The need for collaboration between the veterinary and human fields is increasing due to the rise in several infectious diseases that cross human-animal barriers and need to be addressed jointly. However, such collaboration is not evident in practice, especially for non-zoonotic diseases. A qualitative research approach was used to explore the barriers and enablers influencing collaborative efforts on the development of vaccines for the non-zoonotic RSV virus. It was found that in the European context, most veterinary and human health professionals involved in RSV vaccine development see themselves as belonging to two distinct groups, indicating a lack of a common goal for collaboration. Next to this, the different conceptualizations of the OH approach, and the fact that RSV is not a zoonotic disease, strengthens the opinion that there is no shared need for collaboration. This paper adds insights on how, for a non-zoonotic situation, collaboration between human and veterinary professionals shaped the development of vaccines in both areas; thus, improving public health requires awareness, mutual appreciation, and shared goal setting.
