FAQ
Frequently Asked Questions
No. A vaccine stimulates your own immune system to produce active, long-lasting immunity. An antiserum provides ready-made antibodies for immediate, but temporary, passive protection.
It is typically produced by injecting an animal (like a horse or rabbit) with a specific antigen (e.g., a toxin or inactivated virus). The animal's immune system produces antibodies, which are then harvested from its blood to create the serum.
Risks can include allergic reactions (especially to animal proteins), serum sickness (a delayed immune reaction), and the potential transmission of blood-borne pathogens, though modern processing minimizes this.
Not precisely. An antitoxin is a type of antiserum specifically raised against a biological toxin (e.g., tetanus antitoxin). All antitoxins are antisera, but not all antisera are antitoxins (e.g., antiviral antisera).
