First chickens vaccinated against avian influenza virus

In the Netherlands, the first step has been taken in the fight against avian influenza: 1,800 day-old chicks have been vaccinated against highly pathogenic avian influenza. This field trial, initiated by the Ministry of Agriculture, Nature, and Food Quality, marks the first time chickens in the Netherlands have been vaccinated against this virus.

Minister Piet Adema emphasizes the importance of this effort, considering the devastation that avian influenza has caused in both the poultry sector and among wild birds. This vaccination endeavor aims to reduce the number of infections in domesticated poultry.

Field research

The choice of vaccines used is based on previous laboratory research by Wageningen Bioveterinary Research. This research indicated that two specific vaccines were effective against the virus. Now, various institutes, including Wageningen University & Research and Utrecht University, are examining the effectiveness of these vaccines under real-world conditions.

The field trial consists of various test groups. To verify efficacy, certain chickens are tested in a laboratory at specific intervals. During this, the health and welfare of the chickens are paramount; products from these chickens will not be sold.

Vaccination trajectory

The entire trial extends until the third quarter of 2025. Results are anticipated in 2024. It is vital that the vaccines not only combat symptoms but also prevent the spread of the virus.

The ultimate goal is a responsible vaccination trajectory that considers both animal and public health. In addition to this field trial, a larger-scale pilot is planned for 2024, involving several poultry farms. This pilot depends on European approval and the results of earlier trials. It will also address trade impacts and the detection of potential infections despite vaccination.

In conclusion, poultry farmers are urged to remain vigilant. They must report suspicious cases quickly and maintain strict hygiene regulations to minimize the risk of infection.
