Tim Friede has built his resistance to snake venom by injecting himself with diluted venom, Metro.co.uk reported.

Friede, whose arm balloons up due to a potentially fatal allergic reaction, anaphylaxis, hopes that self-torture would help him to show millions of people that immunity is possible.

He said that it’s the only way people will believe it, and this is the true test of the credibility of self- immunization.

Friede, keeps 100 snakes in his basement in Milwaukee, Winsconsin, US, and goes through regular medicals to be sure he has not suffered any organ damage.

He insisted that by building his own resistance, he can make way for a vaccine that can save 125,000 people who die from snakebites every year.
