<h3>What is a virus?</h3>
A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).
A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.
Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.
