Safety and immunogenicity of the anti-cocaine vaccine UFMG-VAC-V4N2 in a non-human primate model.

A promising strategy for cocaine addiction treatment is the anti-drug vaccine. These vaccines induce the production of anticocaine antibodies, capable of linking to cocaine, and decrease the passage of cocaine throughout the blood-brain barrier, decreasing drug activity in the brain. Our research group developed a new vaccine candidate, the UFMG-V4N2, to treat cocaine use disorders (CUD) using an innovative carrier based on calixarenes.

The GNE-KLH anti-cocaine vaccine protects dams and offspring from cocaine-induced effects during the prenatal and lactating periods.

Protecting children from prenatal cocaine exposure is a significant challenge for physicians and childbearing women with cocaine use disorder. Cocaine use is highly prevalent among reproductive-aged women and prenatal cocaine exposure produces obstetric, foetal neurodevelopmental and long-term behavioural impairments. Cocaine crosses the maternal and foetal blood-brain barrier and the placenta by diffusion.
