Types Of Poultry Vaccines And Their Importance

Marek's Illness

Chickens should be vaccinated against Marek's disease on the day they hatch, usually in the hatchery. It is administered by an injection into the back of the neck's muscle. The vaccine is less successful after the chicks leave the hatchery because they have most likely been exposed. The vaccine only protects against tumors and paralysis caused by Marek's s disease. It has no impact on the birds being infected with the Marek virus and shedding it. Marek's s disease affects chickens under 16 weeks of age the most. Though turkeys and game birds (such as pheasants and quail) are susceptible to the disease, they are rarely vaccinated.

Newcastle disease is a type of infectious disease that affects chickens.

Newcastle disease vaccinations are given to chickens and turkeys regularly. The vaccine includes a virus that has been attenuated. This means the virus is still alive, but its capacity to cause disease has been greatly diminished. It can be given as eye/nose drops or in the drinking water. Pullets are often injected with killed virus vaccines just before the start of egg development.

Newly hatched chicks can be vaccinated at the hatchery, but Newcastle disease-vaccinated chicks cannot be delivered by mail. Between 10 and 35 days, a combination Newcastle and infectious bronchitis attenuated vaccine is usually administered. The vaccine is needed for breeder and layer chicken flocks.

For this vaccine type, additional vaccines should not be needed. However, in breeder flocks, the high antibody levels acquired from repeated vaccines ensure that passive immunity is passed on to the developing chick through the egg.

If you want to add pullets or mature chickens to your vaccinated flock, you can give them the Newcastle disease (B- 1) vaccine by drinking water, intraocular injection, or intranasal injection. Four weeks later, the more reactive LaSota Newcastle disease vaccine is given.

At 4 weeks of age, turkeys are typically vaccinated against Newcastle disease, and then again when the breeders are housed.

Bronchitis Infectious

Infectious bronchitis and Newcastle disease are often mixed with a single vaccine. It can be provided at the hatchery or when the animals are 10– 35 days old. It's a tweaked live-virus vaccine that usually contains the Massachusetts serotype of bronchitis virus. Vaccines are only successful if they contain the correct virus serotype for a specific region. Vaccination is not recommended during an outbreak.

Infectious Laryngotracheitis

Before vaccination against infectious laryngotracheitis, state approval is required (ILT). Vaccinate only if you have a problem on your farm or in your neighborhood. If a producer refuses to vaccinate, all chickens on the property, including any new birds added later, must be vaccinated. Boosters should be taken once a year. Since the virus is an attenuated vaccine, if any of the chickens do not receive vaccinations, the virus will spread and reactivate. In such cases, a lack of vaccination may result in a disease outbreak.

The vaccine is provided in the form of an eye or nose drop. The birds must be at least four weeks old. Younger birds have fewer predators.

Rapid diagnosis and vaccination will also prevent an outbreak in an infected flock from spreading.


There are many common poxviruses, including pigeon pox, quail pox, canarypox, psittacine pox, and ratite pox, in addition to fowl pox. Pigeon pox is a contagious disease that affects pigeons, chickens, turkeys, ducks, and geese. Canaries, ducks, sparrows, and possibly other birds are infected by canarypox. Exposure to one of the viruses can often, but not always, lead to the production of immunity to that virus as well as one or more of the others.
