The decision of having animal testing has had a large impact on humans.
A positive effect of animal testing on humankind are medical advancements to find new vaccines and cures.
Frankie Trull, science advocate and president of the Foundation for Biomedical Research (FBR), says, "An immediate end to animal research in the U.S. would be a death sentence for millions of people around the world," she told Newsweek. "If you've ever taken antibiotics, had a vaccine, had chemotherapy, an MRI, a blood transfusion, dialysis, an organ transplant, bypass surgery or joint replacement, you have been the beneficiary of research that started with lab animals."
Another positive effect of testing on humans is that the testers are getting paid for their job, to supply their family with what they need.
Animal testing and the drugs that are used can be misleading as even though some animals are apparently 99.9% the same genes as humans, there is a 0.1% of possibility with things that could go wrong, even if the drugs are approved and labelled ‘safe’, in the approval process.
There is proof that this is real, as an experimental therapy conducted by a person called Te Genero in 2006 had 6 humans that were all injected with a drug called TGN1412, that was passed ‘safe’, in tests. After they were injected, they began writhing on the floor in agony.
Many scientists who have seen the deformities, gruesome sights and heard the animals cries later end up with depression and criminal records due to the guilt and pity for the animals.
In the 1950s to the 1960s, a drug called thalidomide caused an around 10,000 birth deformities and thousands of baby deaths worldwide. The babies suffered from a disease called phocomelia, where limbs don't develop properly.
Thalidomide had been given to pregnant women to help reduce morning sickness, but unfortunately, it turned out to be toxic to developing babies.
Some medications and drugs that scientists test on animals may not have the same effect it has on humans, so humans may even die or develop serious illnesses from pharmaceuticals that have a totally different reaction in animal bodies.
