Doctor Who did that? I must have missed that episode.
Ivermectin is not the first alternative therapeutic that the powers that be have tried to brainwash peoples minds as being worthless or dangerous, long before that they did it to colloidal silver. You may need it someday if they release the smallpox virus as the article suggests. I don't know if Ivermectin works on smallpox, but there was a couple of studies conducted with colloidal silver on smallpox.

"Colloidal silver was found to show remarkable efficacy against the smallpox virus. Collargol and Protargol were the two medicinal preparations of colloidal silver used in the study. The reduction in concentration of viral particles was about 11 000 and 700 times for collargol and protargol respectively" (Bogdanchikova et al. 1992).

I pray the Good Lord will look after Dr. Zelenko.
