How is a tick vaccine given? - in detail
The administration of a tick vaccine follows a strict protocol to ensure efficacy and safety. The product is supplied as a sterile liquid or lyophilized powder that must be reconstituted according to the manufacturer’s instructions before use.
The first injection is given subcutaneously or intramuscularly, depending on the label. Common sites include the dorsal cervical area in dogs and the neck or shoulder region in cattle. Prior to injection, the chosen site is cleaned with an alcohol swab and allowed to dry. A sterile needle and syringe are used; the needle gauge typically ranges from 22 to 25 G for subcutaneous delivery and 20 to 22 G for intramuscular delivery.
A typical schedule consists of:
- Initial series – two doses administered 2–4 weeks apart. Each dose contains the full recommended volume (often 1 ml for small animals, 2–5 ml for larger livestock).
- Booster – a single dose given 12 months after the second initial injection. Some formulations allow an earlier booster (6 months) if high tick pressure is present.
- Optional revaccination – yearly administration for continued protection, especially in endemic regions.
During each injection, the practitioner must:
- Verify the animal’s identity and health status.
- Confirm the vaccine’s expiration date and integrity of the vial.
- Draw the exact volume, avoiding air bubbles.
- Inject at a steady pace, withdrawing the needle smoothly to minimize tissue trauma.
- Observe the animal for at least 15 minutes after administration for immediate adverse reactions such as swelling, redness, or anaphylaxis.
Storage requirements are critical: the vaccine must be kept refrigerated at 2–8 °C, protected from light, and never frozen. Once opened, the vial should be used within the time frame stipulated by the manufacturer, typically 30 minutes, to preserve potency.
Documentation includes recording the date, dose, route, injection site, and batch number in the animal’s health record. This information supports traceability and facilitates timely booster scheduling.
