Ruscetti well ventilated his annoyance over what he calls the "whisper campaign" about contamination. For according to the Nijmegen Dutch researchers, the Americans have blood samples contaminated or polluted. Ruscetti may include the support of Prof. Dr. John Coffin, both linked to the NCI as at Tufts University in Boston. He is considered one of the most prominent retrovirologen world.
"People have raised the issue of contamination," said Coffin. "But nothing is known about at the moment. There is no proof. Much of the research is done at the NCI, in the laboratory of Francis and Sandra Ruscetti. They have a long experience with these viruses and are very cautious. "
Coffin emphasized again that doing a replication study implies that the exact same manner. "None of the negative studies have been published so far, the virus is grown," said Coffin. "Only in the Science study has been done, and that is a very strong point."
