DNA Vaccines, After the DNA vaccine is injected - Coggle Diagram
DNA Vaccines
Begin
Started testing in the 1990s.
Produces strong immune responses
Relative safety
Vaccination goal achieved
Against the most evil diseases of the time
Fever
HIV
Cancer
DNA vaccines in future
It will change in the relative near future
HIV and cancer patients
Scientists foresee continued breakthroughs in the vaccines
$244 milion in 2013
$2.7 bilion in 2019
New biotechnologies and nanotechnologies are helping to improve the vaccines
advancements lead to the eradication of currently incurable illnesses.
goals
building a potent humoral or antibody, response
creating a strong cellular response
immunity formation
prompt helper T cells and B cells
activate cytotoxic 'killer' T cells
effect
benefit
cost effective
well tolerated by patients
drawback
virtually all remain
in clinical trials
disrupt cellular
processes
produce anti-DNA antibodies
The process of creating a DNA vaccine.
use of genetic material from viruses or bacteria
isolate the gene from the target pathogen
splice the viral gene into a double-stranded DNA vector ( bacterial plasmid)
vaccinating
vaccines are converted into liquid forms to be injected into the body
or shot directly into tissue using the "gun gene."
