A vaccine delivers pre-formed active antibodies for immediate cure, whereas a serum stimulates the patient's body to slowly create memory cells. A serum provides ready-made, pre-formed antibodies for immediate passive immunization against acute toxins, whereas a vaccine introduces antigens to stimulate active antibody and memory cell production for long-term protection. A serum contains weakened antigens that provide lifelong immunity, whereas a vaccine consists of synthetic antibiotics that kill bacteria. Both serums and vaccines work identically by administering heavy doses of broad-spectrum chemical antibiotics directly into the bloodstream.
