Tetanus Prophylaxis Guidelines (Harrison’s Reference):
📌 If Tetanus Toxoid (TT/TD) was given within the past 5 years:
No booster required, even for minor dirty wounds
The body has sufficient protective immunity
🟢 Your Scenario:
Vaccinated 7 months ago = Protected
Scratch only, no major open/dirty wound = Low-risk exposure
🟢 Conclusion:
NO need to take another tetanus shot for this minor injury.
You are still under protection from the vaccine taken in December.
📘 Reference:
Harrison’s Manual of Medicine: Booster needed only if:
Last tetanus shot was >5 years ago for dirty wounds
Or >10 years ago for clean minor wounds
Would you like a tetanus immunization validity chart or wound-risk decision table?
