Developing a Universal Flu Vaccine

The video discusses the challenges of developing a long-term flu vaccine due to the virus's rapid evolution. Scientists in Ghent, Belgium, are working on a vaccine targeting a stable protein in the flu virus, which could provide consistent protection. This approach could simplify production and reduce costs. However, large-scale testing is needed to prove its effectiveness, which poses financial challenges. Despite differing opinions, the team remains optimistic about their method's potential.
