Talk to General Physician on Tetanus Vaccine Overdose

I used to play cricket a lot. In my childhood i was told by doctor to get a tetanus injection everytime u get hurt. I used to get hurt a lot while playing nd i used to get a shot everytime. Sometimes 2 shots in 2 days and sometimes 2 shots in a week. I used to get the shots everytime i got a wound on field. Now i read that u only need one shot in 10 years. Its been many years and i have not taken any shot now. But can i get any serious diseases e.g. blood cancers or anything from that overdose?
