Yes, my mistake. Tetanus toxoid is without the diptheria.
T/D has both. Not the same but both protect against Tetanus.
I found this on a medical website. I hope this helps:
Tetanus toxoid is available by itself, or frequently as one of three components in a vaccine. It can be combined with diphtheria toxoid and pertussis vaccine (DTP) for primary immunization of children, and with reduced diphtheria toxoid (Td) for immunization of older adults and children.
