Safety trials


n many countries it is a legal requirement that all drugs and vaccines (not just for HIV) are tested on animals to ensure safety. In the United Kingdom for example, the Medicines Act of 1968 1 states that all new pharmaceutical products must be tested on at least two different species of live mammal, one of which must be a large non-rodent. This legislation was introduced shortly after the discovery that the drug Thalidomide could cause serious physical deformities in babies born to mothers who had taken it during pregnancy. Thalidomide was not thoroughly tested on animals (particularly pregnant animals) before it was prescribed to women, and this case is the root of many countries’ animal testing safety laws today.
