JERUSALEM, March 25 (Xinhua) -- Israel Defense Forces (IDF) had tested Anthrax vaccine on soldiers in the early 1990s during secret research project without disclosing full details, according to a report published on Wednesday.

The report of the experiments was approved for publication Wednesday evening by Israeli High Court of Justice, following a three-month legal battle, Ha'aretz said on its website.

IDF's Medical Corps and the Nes Tziona Biological Institute held the experiment, nicknamed "Omer 2," during the first part of the 1990s that included 716 IDF soldiers from a pool of some 4,000.The test was aimed at determining the efficacy of an Anthrax vaccine, said the report.

The report alleged that those conducting the experiment failed to inform soldiers about the dangers of the vaccine and possible side effects.

The report also doubts whether the experiment fulfilled any operational purpose, saying that selecting soldiers as the sample group was a violation of ethical principles.

The report was drafted by a special committee of doctors, a legal advisor, and a scientist from the Israeli Weizmann Institute of Science.
