EFFECTIVE VACCINATION

Chicken’s own immune system is its best doctor. The immune system has tremendous potential and it needs to be used systemically to prevent disease outbreaks. Hence, vaccination is a powerful and most proactive control measure to support effective bio-security program. Over the years throughout MVP’s experience in advising our clients, outline below are the key factors we identified to ensure effective vaccination.

Use of match strain of viral vaccine

Using homologous strain of viral vaccine with circulating virus can ensure optimum protection. Superior specificity of developed humoral antibodies associated with homologous strain vaccine help producing optimum protection from clinical infection and viral shedding.

Proper vaccine storage and cold chain management

Proper storage and cold chain management is an utmost importance as temperature has direct effect to viral efficacy. Alternatively, thermostable vaccine can be an option especially in hot country as they are more stable and able to maintain their potency amidst temperature fluctuation. An example would be MyVAC ND V4 Heat Resistance vaccine we produce.

Booster and schedule

Initial dose vaccine is a primer to chicken’s immune system and the need of booster at timely schedule is crucial in to maintain the antibodies level above the minimum protective titre. Titre anything below minimum protective antibody level can put chicken highly at risk of infection.

Host factor

Several host’s factor such as maternal antibody and sub-clinical infection plays huge role in ensuring effective vaccination outcome. Maternal antibody profiling help vaccine timing and prevent vaccine neutralization. Vaccinating only healthy chicken should always be a practice in order to ensure optimum interaction between vaccine and immune system and hence producing a positive result from vaccination.

    Its not unusual for avian influenza viruses to circulate among the bird population. But highly pathogenic influenza viruses are a different story. Highly pathogenic is not the same as highly friendly or highly likely to not cause much trouble. Merriam Webster defines pathogenic as causing or capable of causing disease. Therefore, someone telling you, the date was fun, although I found you highly pathogenic, probably means that there wont be a second date. Low pathogenic avian influenza (LPAI) A viruses tend to be relatively harmless, often causing no disease. If they do cause illness, it is usually mild, possibly resulting in no more than drops in egg production or some ruffled feathers.

    It can be challenging to control the spread of HPAI viruses once they have infected enough wild birds. Wild birds dont tend to follow travel restrictions. Asking them to answer a bunch of questions at the airport is not going to keep them from flying around.
