Uses and Vaccination Program
  Uses:

Benefit of uses of Bangla® IBD Vac

·         Prevents clinical symptoms of Infectious bursal disease (Gumboro Disease).

·         In the absence of maternally derived antibodies (MDA ), it can be applied to 1-day old chicks.

·         It induces immunity against infectious bursa disease even when average levels of maternal antibodies are present (breaking through the MDA titres ≤ ELISA (IDEXX standard) titre 200)

·         Bangla® IBD Vac Protects against bursal damage

·         No immunosuppression or secondary infection

 

Vaccination program:

·         Where there is low level of maternally derived antibodies (MDA ) present in chicks, this vaccine is recommended at 7 to 12 days of age.

·         In case the antibody level is very variable it is advised to vaccinate the fowls twice with an interval of one week. In that case,

first vaccination should be done at 7 days of age to correct the flock heterogeneity of MDA, and   the Second one is given at 14 days of age to ensure all birds are homogenously immunized

Immunity
  The first signs of the antibody response are observed one week after vaccination.

In fowls an adequate immunity against IBD will last for approximately 6-8 weeks.  For longer protection revaccination is necessary.

Vaccination Reaction
  Post-vaccination reactions have not been observed after the vaccination of healthy fowls.

Duration and intensity of the vaccination reaction and the establishment of a solid immunity are dependent on the health and condition of the fowls.  Hygiene and management are also important in the post vaccination period.

Directions For Use
  A. Intra-nasal/Eye Drop Application

Dissolve the vaccine in supplied solvent or deionized water (Usually 5 ml for 100 doses, 11 ml for 300 doses, 17 ml for 500 doses and 33 ml for 1000 doses) and administered by supplied standardized dropper. One drop should be applied from a height of a few centimeters onto one nostril or eye.

B. Administration via the drinking water

Mix the dissolved vaccine with water as shown below:

Age of birds Water per 1,000 doses vaccine
2-4 weeks 10 Liter
4-8 weeks 20Liter
       8 weeks or older 40 Liter

 

 

C.    Spray Method

Remove the aluminium seal and rubber stopper from a vial of vaccine. Half-fill the vial with cool, distilled water, then replace stopper and shake until vaccine is in solution. Pour vaccine into a clean container. For day old chicks, add approximately use 250 ml of cool water for 1000 birds and for older birds add 500 ml of cool water for 1000 birds.

 

The vaccine medicated water should be spread evenly over the correct number of fowls, at a distance of 30 to 40 cm.

Withdrawal period
  None
Storage
  ·         Store in the dark between 2 ºC and 8 ºC.  Do not freeze.

·         Avoid prolonged or repetitive exposure to high ambient temperatures following withdrawal from the refrigerator prior to use.

·         Protect from exposure to direct sunlight.

Package quantities
  Glass Vials each containing 500 and 1000 doses in packs of 10 vials and packed in cardboard boxes.
Further information
  A good immune response is reliant on the reaction of an immunogenic agent and a fully competent immune system. Immunogenicity of the vaccine antigen will be reduced by poor storage or inappropriate administration. Immunocompetence of the animal may be compromised by a variety of factors including poor health, nutritional status, genetic factors, concurrent drug therapy and stress. Under certain conditions, for example extreme disease pressure and variant challenge, fully immune birds may succumb to disease. Therefore, successful vaccination may not be synonymous with full protection in the face of a disease challenge.
