Tetanus bacillus is relatively common in daily life. Once an infection of this kind occurs, or is suspected, a tetanus vaccine must be administered. The effectiveness of the tetanus vaccine lasts about a week. After this period, it no longer has any special therapeutic effects. This means that administering the vaccine during the onset of the disease can only temporarily help with prevention. If similar infections occur in the future, the vaccine should be administered again. Although the effective period of the tetanus vaccine is very short, as long as it is administered promptly when there is a risk, its safety is still relatively high and it can provide better prevention.
