Human DNA vaccines are highly effective against wide range of infectious disease

 

Human DNA vaccines

The first step in developing DNA vaccines is to conduct clinical trials. Although many animal DNA vaccines have been approved for use in human trials, many human DNA vaccines are still in the early phases of development. Although successful testing in animal models led to the development of these vaccines, testing in humans requires approval by an ethics committee. Clinical trials provide valuable information about the safety, efficacy, and adverse effects of DNA vaccines. Clinical trials are conducted in four sequential phases. Phase I evaluates safety, proper dosing, and identifying adverse effects.

Although human genome sequences are highly conserved, these vaccines can be modified to make them more effective. One example is the transfection of DNA with HIV-1 Env. HIV-1 Env DNA vaccines showed that the virus's strong promoter is important in enhancing vaccine immunogenicity in mice. Another candidate vaccine antigen is hepatitis C virus core protein, which has immunosuppressive properties. To overcome this problem, researchers used an inducible Salmonella promoter to drive the expression of the envelope protein 2 gene.

DNA vaccines have distinct advantages over other vaccine technologies. They are highly stable and easily fabricated. In addition, they are safe to use. Researchers continue to optimize various aspects of the vaccines, including antigen expression, vector design, and co-expression of stimulatory sequences. They are also working to improve the safety and immunogenicity of DNA vaccines. The potential of DNA vaccines is enormous. Just one study in humans has shown promising results, with the next phase of clinical trials in the United States.

The development of DNA vaccines is a fast-paced process. Many DNA vaccines now incorporate adjuncts to aid the entry of DNA into cells and direct the immune response. The distinction between a sophisticated DNA vaccine and a simple viral vector may not be completely clear, but clinical trials have already begun. This technology has the potential to make vaccines much faster and safer. So, why wait? There is an important vaccine that may just save our lives.
