• Advantages of antisera:
1. It induces high levels of antibody in the serum within a short
time after administration, & thus confers a rapid protection
against infection.
2. It can be given before exposure to pathogen as prophylaxis.
3. It can be given shortly after exposure to pathogen.
• Disadvantages:
1. Risk of infection by persistent or latent pathogens.
2. Short duration of protection (usually 2-3 months).
3. Hypersensitivity upon subsequent injection.
