Alberto Torres (Exports Manager, Cobb-Vantress) comments on AI outbreaks as a major disruption in international breeding stock trade, especially poultry meat, during this Engormix interview.
Poultry breeding and genetic improvement became a very specialized research activity majored by a few breeding companies. These companies follow the best disease prevention biosecurity to protect their stocks. HPAI is a deadly disease that wipes out the flock in two days, and there is no way to save leave exporting the diseased chicks. Good vaccines are being manufactured to prevent the disease in lower level breeding and commercial stocks. No vaccination policy is making many flocks vulnerable to disease outbreaks and the virus multiplies in the area in large scale. Hence allowing vaccination in place of stamping out will reduce the viral load in the country.
This HPAI virus mutates very often, developing a good vaccine against it is just not possible, cross protection in mutated strains is very difficult to achieve, the breeding companies should breed for strong immune system capable of handling the virus and its mutants, and vaccine manufacturer should produce multi valent ( original virus and its mutants) vaccine for the market, Or develop birds that can resist immunosuppression of all types.
COVID also is a mutating virus. They found some technology. If we work on it I am sure a suitable technology can be evolved. Sitting with stamping out process is multiplying the virus in un vaccinated flocks much faster. The teams working with mortality flocks are at a higher risk
