High-quality immunological adjuvants

Lebak Trading SA is based in Uruguay a country noted for being a protagonist in biotechnology referred to combat of many animal health diseases as Clostridials, Rabies, Brucellosis and Foot and Mouth disease vaccine in the continent.

Our formulas have all the background born in the 80’s following studies developed in 1975 by the Pan American Foot-and-Mouth Disease Center, belonging to the Pan American and the World Health Organizations, PAHO/WHO.

These oily emulsion adjuvants were developed regionally to help in the eradication campaigns that were being implemented in South America. The oil adjuvants would permit FMD vaccination twice a year only whilst maintaining real immunity for six months until revaccination.

TThe principle of slow antigen liberation (slow release) was fundamental to increase the vaccine’s efficacy, potency and immunity coverage.

The oily adjuvant which is today formulated at LEBAK specifically contribute to eradicate Foot-and-Mouth Disease in Uruguay, but it can be used in other veterinary vaccine formulations veterinary vaccines. In 1994, using this vaccine elaborated by Santa Elena Laboratories in the EUBSA plant, brought about the eradication of the disease in Uruguay and Chile.

After first eradication in the country, LEBAK TRADING was created to produce their successful adjuvant for regional use as an alternative one to those imported from Europe at high costs. The brand ADYUVAC 50 and ADYUVAC 70 were created by LEBAK TRADING.

This adjuvant has been used in the production of millions of doses of foot-and-mouth disease vaccines in South America, around one thousand two hundred million doses of vaccine with excellent results in official laboratory tests and cattle to which it was applied.


Lebak´s main commitment is to develop an effective immunological adjuvant, one that does not cause adverse local reactions, pain or persistent swelling, as well as not determining granulomas that may cause meat to be confiscated at abattoirs during the slaughter and deboning of industrial meat cuts.

Also, Lebak aimed adapting the adjuvant to the costs of vaccines manufactured in South America.

Lebak’s great success has been using excellent quality raw materials over a mix of white mineral oils and other components with injectable characteristics, thus developing several ready-to-use adjuvants having easy and safe use in the animal health vaccine production.

The high points of the adjuvants produced today by LEBAK TRADING are:

  • a) ready to use
  • b) Rapid response of lasting immunity
  • c) Very low local reaction without causing damages to skin or meat discards at the slaughterhouse
  • d) Made with high quality injectable components
