Passive Immunisation Strategy

Passive immunisation strategy provides exogenous antibodies or immune components conferring immediate but temporary immunity. Monoclonal antibody infusion immediately neutralises pathogens. Convalescent plasma transfer provides polyclonal antibodies. Immunoglobulin pooling from multiple donors provides population immunity. Immediate protection enables treatment of acute conditions.

Complement relative to active immunisation advantages enable rapid protection. Duration limitation from antibody catabolism necessitates re-dosing. Regulatory approval employs accelerated pathways for urgent needs. Post-approval monitoring tracks protection maintenance. Emerging immunological studies optimise immune responses.
