[Comment] Retraction—Effect of vitamin and trace-element supplementation on immune responses and infection in elderly subjects

On Oct 6, 2015, we asked the Dean of Medicine of Memorial University, St John’s, Newfoundland and Labrador, Canada, to conduct a formal investigation into the research by Dr Ranjit Kumar Chandra that culminated in his publication in The Lancet in 1992.1 Chandra gives Memorial University as his address in the 1992 paper, and Memorial University is also acknowledged as supporting the research through a University Research Professorship Award.
