In December, we reported on the case of Dong-Pyou Han, who was found by the Office of Research Integrity to have spiked rabbit blood samples to make it look as though a vaccine for HIV was working.

At the time, Han’s former institution, Iowa State, told us that “one oral presentation and some abstracts will be removed from the web.”

One of those retractions has occurred, in Retrovirology, of “Eliciting broadly neutralizing antibodies against HIV-1 that target gp41 MPER.” Here’s the notice:

This poster presentation (Han et al, 2012) has been retracted on request of the author Michael W Cho. The Office of Research Integrity at the US DHHS has determined that the first author Dong-Pyou Han committed research misconduct and the poster was prepared based on falsified data (The Office of Research Integrity, 2013).

The presentation, which was published in September 2012, has yet to be cited, according to Thomson Scientific’s Web of Knowledge.

For details about the case and investigation, read Tony Leys’ stories in the Des Moines Register, based on hundreds of pages of documents released to the paper.
