I don't believe Miracle-Mineral-Supplement kills viruses personally. Though I do believe it can alleviate many of the symptoms caused by the virus to the point of making it negligible.
PS. I also don't think 2 drops is sufficient to address the symptoms of a cold. ie, in most cases, it takes several drops(depending on body weight) several times per day to get to the point where their is sufficient Miracle-Mineral-Supplement to combat most ailments. ie, between 7 and 19 drops type thing(depending on body weight).
