PLOS Neglected Tropical Diseases, lays the ground for further research to determine if the technology can also be effective against COVID-19 in humans.Conventional vaccines use a weakened or inactive pathogen to train a person’s immune system to respond to the pathogen.However, DNA vaccines deliver part of the genetic information of the pathogen into a person.
This then produces the antigens of the pathogen — the substances that trigger a person’s immune system to produce antibodies.These antibodies can then offer protection against an infection of the full pathogen in the future.Studies on DNA vaccines emerged in the early 1990s.
