Professor Venugopal Nair, Scientist Emeritus at The Pirbright Institute, said: "Findings from this paper on the origins of virulence, particularly associated with the genetic sequences of the ancient Marek's disease viruses, will provide great scientific opportunities to explore the molecular mechanisms of increasing virulence of this virus that coincided with the intensification of poultry farming from the 1960s."

He added that Covid-19 vaccines have been found to reduce transmissions substantially, whereas chickens inoculated with the Marek’s disease vaccine were still able to transmit the disease.

The theory appears to have its roots in a 2015 paper about vaccines for a chicken ailment called Marek’s disease.

Sacrificing chickens was not the solution the poultry industry adopted for Marek's disease virus.
