Essential Knowledge for Vaccine Administrators Before Vaccination:

2020-03-05

The purpose of vaccination is to protect animals from diseases, but sometimes vaccines fail to reduce disease prevalence, and accidents may occur before immunity develops. Severe pain, drooling, restlessness and other side effects may appear immediately after vaccination, and in some cases, animals may even die.

To avoid such incidents, vaccine administrators must follow certain guidelines:

1. Always check the vaccine's expiration date to ensure it hasn't expired.

2. Keep vaccines in a cool box or flask until use.

3. Shake the vaccine bottle well before use to ensure proper mixing.

4. Keep vaccine bottles away from direct sunlight.

5. Complete vaccination within 1 hour of opening the bottle.

6. Early morning is the best time for vaccination.

7. Vaccinate in shaded areas or under trees.

8. Only administer vaccines to healthy animals.

9. Ensure subcutaneous vaccines are not accidentally injected into muscles.

10. Never vaccinate sick animals.

11. After use, vaccine vials should be buried, not broken.

Reasons why vaccines may fail:

1. If proper temperature is not maintained during transportation.

2. Vaccinating sick animals, as they won't produce adequate antibodies.

3. When the virus's internal DNA structure changes, making old vaccines ineffective.

4. If infection is caused by a different virus than what the vaccine targets.

5. Poor vaccine quality due to manufacturing issues.

6. Incorrect dosage administration, rendering the vaccine ineffective even if everything else is correct.
