The key to this process: the immune response is more complete with the DNA method than it is with standard vaccines because they also stimulate the production of killer T cells, which are important in controlling some types of infection (2).”
What Do DNA Vaccines Offer?
DNA vaccines are efficient at generating T-cell responses that may kill targeted cancerous cells or cells infected by the targeted virus or bacteria.
DNA vaccines may therefore also be used as a therapeutic to treat existing disease. This capability provides the potential to treat chronic infectious diseases such as HIV and hepatitis C virus, as well as the possibility to develop therapeutic cancer vaccines.
DNA vaccines can potentially be developed from concept to FDA approval in eight to 10 years, compared to the up to 20-year period it took to develop the chickenpox vaccine.
DNA vaccines can be readily manufactured using off-the-shelf, well-proven fermentation technology.
- DNA vaccines — in most cases — do not require cold storage and distribution.
“And unlike the old vaccine model, DNA vaccines can’t actually cause disease — a big sticking point for the vaccines we use today (2).”
