Animal testing is one of the major issues we are confronting with. It is a matter of fact that whenever, a new medicine or vaccine is to be developed, It will be tested on animals. In the last two decades, heaps of animal were used for the clinical trials of vaccine. Recently, National Assembly has passed a rule wherein, animal testing has been included in heinous crime list against which, many pharmaceutical companies and research societies defied. Although this positive development will abstain pharmaceutical companies from clinical trial of vaccines on the animals, It will also encourage them to find other legitimate ways to resolve this issue. Different NGOs are working tirelessly to find other resources to address this issue which will ensure the presence of animals on earth.
