Vaccines consist of attenuated microorganisms or their particles that are designed to activate the immune system and create a memory in the event of an outbreak.

1. Newcastle Disease: It is a disease caused by a paramyxovirus that is very contagious and causes high mortality rates in poultry. Vaccination of poultry against Newcastle Disease is essential to prevent outbreaks in poultry farms.

2. Avian Influenza (Bird Flu): A viral disease that in some cases can affect both poultry and humans (zoonosis). Vaccines reduce the spread of the virus among poultry, thereby reducing the risk of transmission to humans.

3. Marek’s disease: A viral disease caused by a type 2 herpes virus that primarily affects chicks and causes tumors and neurological disorders.

4. Avian cholera: Caused by a bacterium of the genus Pasteurella, which can cause significant morbidity and mortality.

5. Avian Infectious Bronchitis (IB): This is a viral disease caused by a highly contagious coronavirus that affects the respiratory tract of poultry. This virus can reduce egg production and degrade eggshell quality.

6. Gumboro disease (infectious bursitis): This is a viral disease caused by a birnavirus that affects the immune system of young poultry, causing damage to the bursa of Fabricius and weakening immunity. Vaccination is essential to prevent the spread of this disease and to protect young poultry.
