...ley's knedels are biomimics - they are designed to behave like viruses, which biochemically are attracted to hosts that they seek to infect. But a biomimic does not run the risk of a live virus, which, as in the case of the 18-year-old who died, may have toxic or, on the other hand, negligible effects.
