Vaccine Safety

Vaccine Safety Monitoring Activities

ISO has a three-part mission that supports CDC's leadership role:

To perform high-quality vaccine safety research.
To assess causality and preventable risk factors.
To identify adverse events following immunization (AEFIs) through public health surveillance.

ISO conducts six primary vaccine safety activities:

2009 H1N1 Vaccine Safety

For the best source of vaccine safety information on the 2009 H1N1 influenza vaccine, CDC encourages you to stay informed by checking the www.cdc.gov/h1n1flu.

Clinical Immunization Safety Assessment (CISA) Network

CISA studies the pathopsyiology of adverse events following immunization, identifies risk factors, and develop guidance to help doctors.

Emergency Preparedness

In the event of a threat of disease outbreak in which a mass vaccination campaign is needed, emergency preparedness activities are activated to ensure that vaccines remain safe.

Vaccine Adverse Event Reporting System (VAERS)

VAERS is a national reporting system. VAERS serves as an early-warning system to detect medical problems that may be related to vaccines.

Vaccine Safety Datalink Project (VSD)

VSD conducts near real-time surveillance of adverse events potentially associated with new vaccines or changes in immunization schedules.

Partnerships

ISO works with public health officials, academia, as well as international organizations such as the World Health Organization, the Brighton Collaboration, and the Department of Defense.
