How many days should a tick vaccine not be wetted? - briefly
The reconstituted tick vaccine must remain dry and be administered within 24–48 hours; beyond this period, exposure to moisture compromises efficacy and safety. Any vaccine that becomes wet should be discarded immediately.
How many days should a tick vaccine not be wetted? - in detail
A tick vaccine must remain free of moisture for a specific period before administration. Manufacturer instructions generally state that the product should stay dry for up to 30 days after opening, provided the vial is kept at the recommended temperature (2‑8 °C). Exceeding this interval increases the risk of bacterial contamination and loss of potency.
Key points for maintaining dryness:
- Store the unopened vial in a sealed, moisture‑resistant container.
- After removal from refrigeration, keep the vial in a clean, dry environment; avoid exposure to humidity, water splashes, or condensation.
- If the vial is accidentally wetted, discard it immediately; re‑wetting is not permissible under any circumstances.
- Record the date of opening on the label and calculate the allowable dry period based on that date.
When the vaccine is prepared for injection, the diluent must be added only at the time of use. The mixed solution should be administered within the time frame indicated by the manufacturer, typically 30 minutes, and must never be re‑used.
Failure to observe these guidelines can result in reduced efficacy, increased adverse reactions, and potential regulatory non‑compliance. Adhering strictly to the prescribed dry‑storage window ensures optimal protection against tick‑borne diseases.
