Summary:By Josh Loeb Scientists' success in producing pigs resistant to all strains of porcine reproductive and respiratory syndrome (PRRS) should prompt fresh debate on allowing human consumption of genetically modified livestock, a senior vet at the institute that made the breakthrough has stressed. Timothy King, who oversees farm animal facilities at Edinburgh's vet school - and who was the vet for world famous cloned sheep Dolly - said pigs whose DNA was edited so that they could not become infected with PRRS were otherwise unaffected in terms of their health and welfare. Christine Tait-Burkard, lead author of the study, said Edinburgh's gene-edited pigs could serve as 'a kind of ring vaccination' for herds, providing protection for other animals not themselves subject to gene editing.
