[Editorial] Restoring confidence in research integrity (Lancet Oncology)

On July 1, 2015, a US federal judge handed down a 4·5 year prison sentence and a US $7·2 million fine to laboratory manager, Dong-Pyou Han, for falsifying HIV research data. Han admitted that, while a researcher at Iowa State University (Ames, IA, USA), he added human antibodies to blood from rabbits that had been injected with an experimental vaccine, which gave the impression that the vaccine worked. Collaborators attempting to replicate these results uncovered the fraud, and a federal investigation was launched.
