Scientists have been rushing to develop a vaccine for the Zika virus at warp speed ever since the epidemic began. The continued threat has pushed scientists to try creating a DNA vaccine, which could revolutionize all vaccines. The DNA vaccine is basically like something you would read about in a science fiction novel. This kind of technology is extremely cutting edge and would be a huge step forward in the world of medicine.
A DNA vaccine takes genetic material from the virus and then uses just enough of it to cause our bodies to develop an immune response without actually introducing the virus to the body. This completely fixes the issues scientists have had with traditional vaccines, which do introduce the virus to our immune system, usually a weakened version of the virus or a dead version. This then prompts our immune system to respond and fight it without our bodies actually experiencing any of the negative health problem caused by the virus. As you might have guessed, there are plenty of things that can go wrong with these kinds of vaccines, especially for people with immune deficiencies.
The DNA vaccine injects a synthetic form of the DNA from the virus, eliminating any possible health issues caused by regular vaccines. However, up till now it hasn’t been used because it doesn’t absorb well. This problem has now been fixed. The DNA vaccine now delivers a mild electrical current along with the vaccine, which opens cell membranes so cells can absorb the DNA. This allows our bodies to then spur an antibody response. This method is safer and more effective than traditional vaccines. Who knows? Catching a virus could eventually become a thing of the past.
How do you think DNA vaccines could effect and change vaccines as well as health in general around the world?
