tetanus vaccines are 100% protective against tetanus for ten years. the injection does not protect you against any other wound infection -- just tetanus --- so good first aid after any injury is always necessary. there are much better antiseptics than after shave lotion (alcohol) so perhaps you should improve your home first-aid kit. you can always get wound infections.
does tt injection needs to be taken once every 6 months or after sustaining cuts with a sharp object? . i sustained a cut on one of my fingers and blood started oozing out immediately. i washed the wound under running tap water and then applied pressure on it using kitchen tissue. after some time the blood stopped and the cut was hardly visible unless you took a closer look. i then cleaned the wound using aftershave lotion and then covered the wound surface with neosporin gel and bandaged it. it happened 2 days from now. do i need to take a tt injection? the last time i took it in mar 2013.
