ZyCoV-D DNA vaccine immunogenic against SARS-CoV-2 in animal models

In the absence of effective therapeutics or preventives, vaccines have become the focus of attention. Though over 170 vaccines are in preclinical and about 60 in clinical development, very few are based on plasmid DNA technology. However, a new preprint research paper posted to the bioRxiv* server reports the immunogenicity of a DNA vaccine candidate.
