Solution
$A$ person who has received a cut accident and is bleeding needs to be given anti-tetanus treatment because antigen causing tetanus may have entered the body against which preformed antibodies have to be injected to avoid the effect of antigen.
Anti-tetanus injection provides passive immunity by providing preformed antibodies for tetanus.
