In 2016 a DNA vaccine for the Zika virus began testing in humans at the National Institutes of Health. The study was planned to involve up to 120 subjects aged between 18 and 35. Separately, Inovio Pharmaceuticals and GeneOne Life Science began tests of a different DNA vaccine against Zika in Miami. The NIH vaccine is injected into the upper ...
As a result, genetic vaccines and live vaccines generate cytotoxic T-cells in addition to antibodies in the vaccinated individual. In contrast to live vaccines, only parts of the pathogen are used, which means that a reversion to an infectious pathogen cannot occur as it happened during the polio vaccinations with the Sabin vaccine.

Nucleic acid vaccines use mRNA to give cells instructions on how to produce a desired protein. Libre de Droit/iStock via Getty ImagesThe two most successful coronavirus vaccines developed in the U ...
This would both make the vaccine more practical and lower the cost for developing countries. [13] Using a single-injection vaccine has shown to not cause any adverse reactogenicity, which the possible immune response to vaccination, in comparison to two separate vaccinations. [9] There is a candidate vaccine against the Marburg virus called ...
Fears of genes being altered by the residual DNA fragments in COVID-19 vaccines don't stand up to the science.

The vaccine contains a DNA plasmid vector that carries the gene encoding the spike protein of SARS-CoV-2. As with other DNA vaccines, the recipient's cells then produce the spike protein, eliciting a protective immune response. The plasmid also contains unmethylated CpG motifs to enhance its immunostimulatory properties. [2]
In May 2021, Inovio announced the results of preclinical studies on a "pan-SARS-CoV-2" DNA vaccine (INO-4802) and plans to initiate phase I/II studies. The vaccine incorporates common overlapping mutations from several SARS-COV-2 variants of concern isolated from several different countries including Brazil and India. [20]
