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 ...
In 1995, Robert Conry and colleagues described that a humoral immune response was also elicited after vaccination with an RNA vaccine. [13] [11] While DNA vaccines were more frequently researched in the early years due to their ease of production, low cost, and high stability to degrading enzymes, but sometimes produced low vaccine responses ...
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]
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.
COVID-19 vaccine clinical research uses clinical research to establish the characteristics of COVID-19 vaccines. These characteristics include efficacy, effectiveness, and safety. As of November 2022, 40 vaccines are authorized by at least one national regulatory authority for public use: [1] [2] one DNA vaccine: ZyCoV-D [3]
