Can tetanus be killed by the immune system?

Tetanus can usually multiply in an anoxic environment containing blood stasis, but the danger is not tetanus itself, but the exotoxin secreted by this bacterium. This toxin is an exotoxin, which acts on nerve cells after entering the human blood circulation, causing a small amount of death.

So it doesn't mean that white blood cells can't kill tetanus, but it takes time to kill it, but it is during this time that the toxin secreted by tetanus can endanger people's lives.
