It’s understandable to be concerned after injuring your finger, especially regarding the risk of tetanus. A significant skin injury increases the importance of ensuring your tetanus vaccination is up to date, particularly since it has been over a decade since your last booster.

Main Points:

• Risk of tetanus is primarily related to how deep and contaminated the wound is.
• You should receive a tetanus booster if it's been more than 10 years since your last shot, especially for a significant injury.
• Immediate medical attention is prudent given the condition of your finger.

Explanation: Tetanus is caused by bacteria (Clostridium tetani) often found in soil and dust, but it can also enter through puncture wounds or deep cuts where the skin is broken. Even though your knife’s previous use did not involve soil, the injury from slicing can still pose a risk if the skin is significantly torn. Fresh vegetables themselves (like celery or onion) are not typical sources of the tetanus bacteria.

Given you have a noticeable flap of skin and the injury is considerable, it’s better to take a conservative approach. Even if the bleeding has slowed, the injury may require assessment for cleaning and possible stitches.

Next Steps:

1. Seek medical attention as soon as you can. This is particularly important for assessing the wound and determining if you need stitches or special care.
2. Bring your vaccination history with you (if available) to verify when you last received a tetanus booster.
3. Consider an immediate booster shot if it’s confirmed that it’s been over 10 years, as recommended by vaccination guidelines.

Taking these steps will help ensure that you are protected against tetanus and your finger receives the attention it needs. Be reassured that handling this promptly is the best course of action. If you have any further concerns, feel free to reach out.
