6. A double-blind controlled trial was conducted to test methods of transmission of viruses and
the protective ability of vitamin C. 24 male volunteers were recruited for the study. Half of
the men were pretreated for 3 weeks with 2,000 mg of vitamin C daily (4 X 500 mg) and the
other half were given 4 placebo pills daily. The men were all infected with RV16 cold virus
by direct inoculation into the nose. The men were observed for 7 days and during the week
continued to take the pills. All developed colds.
