I believe that animal testing helps. In 1796, Edward Jenner, an English doctor, carried out an experiment on a 8 year old farmer's boy, against Smallpox. He vaccinated the boy with cowpox, and this cured the boy. If Edward Jenner had not experimented on an 8 year old boy, there to this day, would not be a vaccination against Smallpox, and we could all still be suffering and dying from it, and now, scientists cant even experiment on animals without a protest, who ridiculous.
