Will the tetanus injection work if injected within 48 hours after the injury? Yes, receiving a tetanus injection within 48 hours after an injury can still be effective in preventing tetanus infection. However, it’s important to note that the effectiveness of the tetanus vaccine decreases over time, and the optimal window for receiving the vaccine is within 72 hours (3 days) after the injury.

The tetanus vaccine helps stimulate the production of antibodies against the tetanus toxin, providing immunity and protection against tetanus infection. When administered promptly after an injury, the vaccine can help prevent the growth and action of the tetanus bacteria in the body.

If it has been less than five years since your last tetanus vaccine, a tetanus toxoid (TT) booster shot is usually recommended. If it has been more than five years, a combined tetanus-diphtheria-pertussis (Tdap) vaccine may be administered.

However, it’s essential to consult with a healthcare professional or seek medical attention promptly after an injury to evaluate the need for a tetanus vaccine. They can assess the nature of the wound, your immunization history, and other relevant factors to determine the most appropriate course of action. It’s always better to err on the side of caution and seek medical advice in such situations.
