Since you have sustained a cut from a bull, please get the wound assessed at an anti-rabies/healthcare centre as soon as possible. The need for rabies vaccination depends on whether the wound was contaminated with the animal's saliva and on your previous vaccination history.
Next Steps
Take your previous rabies vaccination record/card with you.
Also ask about tetanus vaccination, depending on your vaccination status and the wound.
Do not wait for symptoms of rabies before seeking treatment.
