INTRODUCTION Vaccines are used widely in the world. With the discovery of various vaccines mortality rate caused by various infectious organisms have reduced. Their use has been considered one of the safe and effective measures to control various infectious diseases. Plants offer enormous potential as production platforms for vaccines and therapeutic proteins. Vaccines derived from plants present an alternative to conventional vaccines by facilitating safe and effective oral delivery through intake

Consumption of unpas¬teurized dairy products, contaminated food, and occupational contact are the major risks of brucellosis infection to man (Godfroid et al.,2005). Contact with infected materials such as aborted fetuses, placentas, urine, manure, carcass, and salvaged animals cause human brucellosis in 60%–70% of cases observed (WHO.,2006). Infection by
Human subjects who participate in clinical research make it possible to secure that knowledge. In order to determine if a new drug or treatment is safe or effective, for example, it has to be tested on patient volunteers. By placing some people at risk of harm for the good of others, clinical research has the potential of exploiting patient volunteers. The purpose of ethical guidelines is thus to protect patient volunteers and to preserve the integrity of the science. The ethical guidelines in place
scientific researching has some drawbacks such as it is cruel and inhumane, against some believes, impacts biodiversity etc. However, their use in scientific researches is much more helpful and is more legal because it saves and cures human life, is acceptable in most traditions,
