The technique targets cells infected by viruses and leaves cells without viruses unharmed. But the aim is to kill all viruses. I do not belittle any attempt to get rid of harmful viruses, but the idea that the old good virus is a dead one, may be an error. The authors write: Vaccines require a new vaccine to be developed for each virus or viral strain, must be administered before or in some cases soon after exposure to be effective To overcome [the] shortcomings of existing approaches, we have developed and demonstrated a novel antiviral approach that is effective against a very broad spectrum of viruses Our approach, which we call a Double-stranded RNA (dsRNA) Activated Caspase Oligomerizer (DRACO), is designed to selectively and rapidly kill virus-infected cells while not harming uninfected cells. DRACOs should be effective against numerous clinical and NIAID priority viruses ... We have demonstrated that DRACOs are effective against viruses with DNA, dsRNA, positivesense ssRNA, and negative-sense ssRNA genomes; enveloped and non-enveloped viruses; viruses that replicate in the cytoplasm and viruses that replicate in the nucleus; human, bat, and rodent viruses; and viruses that use a variety of cellular receptors Broad-Spectrum Antiviral Therapeutics Todd H.
