Usually, no. If he completed his primary tetanus vaccination series and received TT/Td within the past year, another booster is generally not required, even for a dirty wound.
However, assess the wound carefully. If his previous vaccination history is incomplete or uncertain, or the wound is deep or heavily contaminated, the prophylaxis decision may differ.
Next Steps
Gently irrigate the wound thoroughly with clean running water or normal saline.
Remove loose visible dirt; don't probe deeply for embedded debris.
Apply a sterile, non-adherent dressing.
Monitor for increasing redness, warmth, swelling, pus, fever, or worsening pain.
Health Tips
Arrange medical assessment today if the injury involved crushing, a deep cut, embedded debris, or a wound over the kneecap that may extend into the joint.
Diabetes increases the risk of wound complications. Antibiotics are not routinely needed for every minor abrasion.
