This technology was Pfizer CEO Albert Bourla’s veterinary speciality.
The entire Special Section of The Economist mentioned above is worth careful reading. It contains important information about the biotechnology being used on unwanted genetics that we know was also used in the Mystery "Covid" Injection, such as Lipid Nanoparticles, mRNA, CRISPR, Genetic Editing and Gene Driving.
You will remember that Albert Bourla (described as a "Holocaust Survivor") led the charge for the Covid Injection Campaign. From the start of his training and for forty years thereafter Bourla specialized exclusively in the Biotechnology of Reproduction and practised perfecting techniques to make unwanted animals infertile over a few generations, especially by gene-drive injection and immunocastration. This is who was placed at the front of your "Covid Mystery Injection Campaign" against the invisible lurgy.
Note how this leads to a relatively slow Massive Infertility Event over three generations, over the rest of this century.
