Abstract
This article has been retracted.
It has been brought to the attention of the journal that ergoferon in ‘Activity of ergoferon against lethal influenza A (H3N2) virus infection in mice’ is an antibody preparation in homeopathic concentrations that was not so described in the manuscript.
The journal does not consider articles reporting on homeopathic products or highly diluted preparations and would normally have rejected it had it been described as such in the manuscript. After extensive discussion with the Editors and other experts, the Editor-in-Chief has decided to formally retract the article. The authors do not agree with this decision.
