Sorry to sound completely dumb but what are the differences ?
Not dumb at all, genetic vaccines are fairly new. First, they are quicker and easier to manufacture than traditional vaccines, so they may be available in larger quantities sooner.
There is also evidence that they'll be more effective and provide broader protection:
Synthetic DNA vaccines: improved vaccine potency by electroporation and co-delivered genetic adjuvants
Here's an excerpt.
Immunological Advantages
The main advantage of DNA vaccines is their ability to stimulate both the humoral and cellular arms of the adaptive immune system. In regards to humoral immunity, the generation of antibodies by B lymphocytes against invading pathogens is one of the most effective defenses mounted by the immune system. Vaccines that utilize live-attenuated microorganisms, killed viral particles, or recombinant viral proteins elicit the production of specific antibodies that bind superficial microbial structures on the target pathogen. Unfortunately, immunological pressure or imprecise genome replication can cause certain pathogens to accumulate mutations that reduces the effectiveness of antibodies originally generated against the pathogen. Typically, antibody responses generated by traditional vaccines target only the specific antigens found in the inoculum, and are poorly able to control similar pathogens that carry either subtle or gross changes to the antigen. Due to the ability to genetically modify the antigen encoded by DNA vaccines, the vaccine can be designed to contain the most highly conserved regions of the superficial, antibody-generating structures on a pathogen, providing a means to generate broadly neutralizing antibodies against pathogens such as HIV and the influenza virus.
