Avian Influenza, also referred to as bird flu or avian flu, is a highly contagious viral infection that primarily affects poultry, particularly domestic birds. This viral infection poses a severe threat to poultry farms, resulting in significant economic losses and exerting a widespread impact on the global poultry farming industry. In this article, we will discuss the threat of Avian Influenza to poultry farms and provide essential measures for safeguarding poultry flocks against this viral infection, with a focus on the utilization of vaccines.


Advantages of SINDER's Inactivated Avian Influenza Vaccines

When it comes to raising poultry such as chickens, ducks, and geese, there are multiple types of avian influenza vaccines available, including live vaccines and inactivated vaccines. The choice of vaccine depends on the specific needs of the poultry and the feasibility of the vaccine.

Live vaccines are prepared using live viral strains that have been appropriately processed and attenuated, allowing them to induce an immune response in poultry without causing severe disease. These vaccines are typically administered to poultry through drinking water or spray methods. Live vaccines have a high immunogenicity, rapidly activating the poultry's immune system and providing long-term protection. However, it is important to ensure the safety and stability of the vaccine strains and to follow the correct vaccination procedures and dosage when using live vaccines.

An alternative type of avian influenza vaccine is the inactivated vaccine, also known as a killed vaccine. This particular vaccine employs inactivated viral particles that are unable to replicate or infect poultry. Inactivated vaccines are typically administered to poultry through injection. They offer notable advantages in terms of safety and stability since the inactivated virus cannot cause disease. However, it may take longer for the immunogenicity of inactivated vaccines to develop, and multiple doses might be necessary to establish lasting immune protection. At SINDER, our company specializes in the production of inactivated vaccines, and we offer the following advantages:


1.We utilize selected virus seeds with a high protective potency against epidemic virus strains.

2.Our vaccines incorporate the Marol-52 Adjuvant, which ensures greater purity and enhanced safety.

3.We employ IKA Double emulsification technology, resulting in vaccines with uniform-sized particles that are easier to administer through injection.

4.Our vaccines are free from extraneous viruses, including MG, REV, REO, CAV, ALV, and other potential contaminants.


Recommended Vaccination Timings for Poultry

The timing of vaccine administration is crucial and should be determined based on the poultry's life cycle and the recommended vaccination schedule for the target vaccines. Typically, early vaccination in the early stages of poultry growth can help establish immunity and provide better protection. Here are some recommended vaccination timings for common poultry vaccines:


Day-old chicks: For day-old chicks, vaccination is generally conducted within a few hours or days after hatching to provide early protection. This may include vaccination against common diseases like avian influenza, Newcastle disease, etc.

Chick stage: During the chick stage, multiple vaccinations are usually administered to help establish immunity. This may involve vaccination against diseases such as avian cholera, infectious bronchitis, etc.

Growing period: Regular vaccination is required during the growing period to maintain immune protection. This may include vaccination against diseases like fowl paralysis, infectious bursal disease, etc.

Adult birds: Adult birds typically require regular vaccination to maintain immunity and prevent disease outbreaks. This may include vaccination against diseases such as avian influenza, Newcastle disease, infectious bronchitis, etc.


It is important to note that the specific timing of vaccine administration should be determined based on the poultry species, farming management plan, and recommendations from vaccine manufacturers. It is advisable to collaborate with a veterinarian or poultry health expert to develop a suitable vaccination plan for poultry and ensure proper vaccination procedures and dosages are followed. Regularly recording vaccination dates and vaccine types is essential for tracking and management purposes.




Protecting poultry flocks against Avian Influenza is crucial for the sustainability and profitability of poultry farms. Vaccination plays a vital role in preventing and controlling the spread of this highly contagious viral infection. SINDER's inactivated Avian Influenza vaccines offer significant advantages, including high protective potency, enhanced safety, and uniform-sized particles for easier administration.

To ensure effective vaccination, it is essential to follow recommended vaccination timings based on the poultry's life cycle. Early vaccination of day-old chicks and regular vaccinations during the growing period and adulthood help establish and maintain immunity against common poultry diseases.

By implementing robust vaccination strategies and adhering to best practices, poultry farms can mitigate the risks associated with Avian Influenza and maintain a healthy and productive poultry population.
