Vaccination against avian influenza does not prevent the virus from circulating

Scientists conducted a study that was supposed to establish the effectiveness of the vaccine against the avian influenza virus. Natalya Moroz, Deputy DIRECTOR of the FGBI ARRIAH, spoke about the study at a conference on veterinary issues in the poultry industry. The report states that the vaccine actually helps in protecting against the virus.

During the experiment, vaccinated birds were infected with the avian influenza virus. According to the results of the experiment, the infected birds survived - that is, the vaccine works successfully as a protection for birds from death. However, scientists drew attention to the fact that the virus continued to stand out for another 6-9 days after vaccination. This means that the vaccine will not protect against the spread of the virus.

As Natalya Morozova explained, it is impossible to achieve 100% immunity in birds in industrial production. This means that even taking into account the vaccination of birds, the virus will continue to run at the enterprise.

According to scientists, the use of the vaccine can help businesses reduce the economic impact of avian influenza, as the birds will stop dying - in particular, it can protect valuable poultry breeding stock. At the same time, vaccination can mask the course of the disease, monthly PCR tests will be required to monitor the HEALTH of birds, and there is a risk that the virus will mutate to fight the vaccine. Thus, there are pros and cons to using a vaccine.
