For this reason, some manufacturers recommend using a booster vaccination to build a higher antibody level. When the manufacturer's directions recommend a booster, it is necessary that it be done at the recommended intervals . This can occur when excessive animal stress combines with entrance of extremely large numbers of virulent disease-causing organisms. This overwhelming infection can overcome even a relatively strong immune protection. Animals can be missed at vaccination time when too many jobs are being done simultaneously.
Organization is very important.
Route of Administration Companies that produce vaccine will specifically label the route of administration and which site of inoculation is preferred. Research by the manufacturer has proven which route is best. If injection in the muscle is specified, the vaccine should not be given by any other route. Your veterinarian should be involved to ensure proper vaccine selection and use. Animal Protection Precautions should be taken to ensure the physical well-being of the animal.
