Flexi Says: Gene therapy is the insertion of a new gene into an individual’s cells and tissues to treat a genetic disorder by replacing a mutant disease-causing allele with a normal, non-mutant allele. Common cold is not a genetic disorder but an viral infection that could not be treated by gene therapy. But DNA vaccine can be a promising option for treatment of common cold. DNA vaccine is the injection of genetically engineered plasmid containing the DNA sequence encoding the antigen that cause a protective immunological response.
