The above article is not an acceptable justification of much of anything. There have been other articles also discussing this idea, however no well done study has ever been performed as of yet.

"A single, non randomised, poorly reported trial of vitamin C as a treatment for tetanus suggests a considerable reduction in mortality. However, concerns about trial quality mean that this result must be interpreted with caution and vitamin C cannot be recommended as a treatment for tetanus on the basis of this evidence. New trials should be carried out to examine the effect of vitamin C on tetanus treatment."

I remain unconvinced. Additionally your stance against vaccination is without scientific or medical justification, so your opinions on this matter are clouded with bias.
