IMPORTANT POINTS TO BE NOTED DURING VACCINATION
♧Animals should be in good health at the time of vaccination.
♧The cold chain of the vaccines wherever prescribed should be maintained till the time of administration to the animal.
♧The manufacturers’ instruction on the route and dosage should be strictly followed.
♧A minimum vaccination coverage of 80% of population is required for proper control of the
disease.
♧It is beneficial to deworm the animals 2-3 weeks before vaccination is carried out for better immune response.
♧Vaccination should be carried out at least a month prior to the likely occurrence of the disease.
♧Vaccination of animals in advanced pregnancy may be avoided even though in most cases nothing untoward may happen.
COMMON REASONS FOR VACCINATION FAILURE
☆Lack of maintenance of cold chain from the time of manufacture till vaccination.
☆Poor immune response in weak and improperly fed animals.
☆Lack of herd immunity due to only a few animals being vaccinated.
☆Poor quality of vaccine – Quality will deteriorate if repeatedly thawed and cooled.
☆Low efficiency or ineffective vaccine – May occur in case of strain variation (eg. FMD).
