Not required.
In fact when Google says that Inj Tetanus Toxoid doesn't give instant immunity it means that if you have never taken Tetanus injection in your lifetime and have taken first injection 1-2 weeks earlier then that injection doesn't give instant immunity.
But in your case you have been taking injections since childhood. So your body had enough time to produce immunoglobulin.
You have enough immunity against Tetanus.
