Adventitious agents and vaccines.
Emerging Infectious Diseases Vol. 7, No. 3 Supplement, June 2001 562 A discussion of adventitious agents and vaccines is pertinent in the context of emerging infectious diseases. Many novel vaccines are produced in animal cell substrates, and emerging infectious diseases may theoretically be transmitted from animals to humans through these vaccines. The challenge of identifying potential advent...
متن کاملEvaluation of Adventitious Agents in MMR & Oral Poliomyelitis Vaccines
Background and Aims: Adventitious agents, especially viral agents are among the most important concerns in viral vaccines. Viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. In this study, adventitious ...

متن کاملAdventitious agents in viral vaccines: lessons learned from 4 case studies.
Since the earliest days of biological product manufacture, there have been a number of instances where laboratory studies provided evidence for the presence of adventitious agents in a marketed product. Lessons learned from such events can be used to strengthen regulatory preparedness for the future. We have therefore selected four instances where an adventitious agent, or a signal suggesting t...
متن کاملVaccines and Antiviral Agents
A vaccine is a biological preparation that improves immunity to a particular disease. A vac‐ cine typically contains an agent that resembles a disease-causing microorganism, and is of‐ ten made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so...
