Different approach
Attenuated nor killed pathogens are involved, nor are pathogen subunits isolated

-
Goals
Once injected, DNA vaccinations prompt helper T cells and B cells to multiply and produce memory cells, as well as activate cytotoxic “killer” T cells, which are the toughest pathogen fighters
This type of dual cellular and humoral response gives long-lasting immunity. Because DNA vaccine plasmids are not living, and thus nonreplicating,there is no risk that they may cause an illness
Vaccine testing results

However, that the technology for improving the vaccines' efficacy has advanced by leaps and bounds since the 1990s.

1 in 1990s,though the vast majority of DNA vaccine are still in clinical trial the development for vaccine have grown tremendously over past several years, and it plays an indispensable role in our medical
*5. Vaccines are still in testing because they are unstable, disrupt cellular processes and produce DNA antibodies, leading to very low immunity.
- In general, genetic material from the virus or bacteria is used to elicit an immune response. Scientists fi rst isolate the gene from a target pathogen and then splice it into a double-stranded DNA vector
3.The steps included neither attenuated or killed pathogens are involved, nor are pathogen subunits isolated. The process often last 10-15 years to complete the development steps before it was approved
- DNA vaccines do not contain a live virus, so one cannot get sick from them, whereas other vaccines pose that risk.
