DNA vaccines - Coggle Diagram
DNA vaccines
Process of DNA vaccines created
use the genetic material from the virus or bacteria to elicit an immune response
isolate a gene from the target pathogen
splice the viral gene into a double-stranded DNA vector
How DNA vaccines is active into the body
Goals
Creating a strong cellular response
building a potent humoral, or antibody, response
They prompt helper T cells and B cells to multiply and create
memory cells and activate cytotoxic “killer” T cells, which gives long-lasting immunity
safer than attenuated vaccines
DNA vaccine plasmids are not living
there is no risk to cause an illness
Experiment of DNA vaccines
Began in the 1990s
They are not widely available today because they are still in clinical trials
The goal is against the most devastating maladies
future expectations of DNA vaccines
Given to HIV or cancer patients in the near future
soon breakthroughs in the vaccines
they are expected to grow to $2.7 billion by 2019
New biotechnologies and nanotechnologies are helping to improve
eradicate currently incurable illness in the not-so-distant future
reason why they remain in clinical trials
They may disrupt cellular processes and produce anti-DNA antibodies, resulting in too low a level of immunogenicity
However, the technology has advanced by leaps and bounds since the 1990s
