Vaccine Safety Datalink

Like VAERS and CISA, the Vaccine Safety Datalink (VSD) is a part of our system that helps make sure our vaccines are safe.

The Vaccine Safety Datalink is a network of nine large health care organizations throughout the United States that work with the CDC “to monitor safety of vaccines and conduct studies about rare and serious adverse events following immunization.”

The Vaccine Safety Datalink monitors vaccine safety and “conducts vaccine safety studies based on questions or concerns raised from the medical literature and reports to the Vaccine Adverse Event Reporting System (VAERS).”

Using Rapid Cycle Analysis, the Vaccine Safety Datalink can even do near real time analysis to detect possible adverse events after vaccination. This helped, during routine weekly vaccine safety monitoring, detect a small increase in the risk of febrile seizures when getting the combination chickenpox and MMR vaccines.

Using and Misusing VAERS Reports

The Vaccine Adverse Event Reporting System (VAERS) is considered “an early warning system to detect possible safety issues with U.S. vaccines.”

Created as part of the National Childhood Vaccine Injury Act in 1990, anyone can report possible vaccine reactions to VAERS. Just remember that just because something is reported to VAERS and is included in the VAERS database, that doesn’t automatically mean that a vaccine caused the reaction.

Additional information is sometimes requested to further look into these reactions, including medical records. Again, it is important to understand that “It is generally not possible to find out from VAERS data if a vaccine caused the adverse event.”

For example, one study of VAERS reports found that only 3% of the adverse events following immunization “were classified as definitely causally related to vaccine received.”

Despite its limitations, VAERS works well.

It was using VAERS data that CDC and FDA vaccine experts quickly discovered that the older RotaShield rotavirus vaccine was associated with an increased risk of intussusception.

Reporting to VAERS

Has your child had a bad reaction to a vaccine or what you think is a vaccine injury?

The CDC advises that “all significant adverse events that occur after vaccination of adults and children, even if you are not sure whether the vaccine caused the adverse event.”

What if your doctor won’t report the vaccine reaction?

While unfortunate, you can simply report the vaccine reaction yourself.

Health care providers are required to report:

  • Adverse events that are listed by the vaccine manufacturer as a contraindication to further doses of the vaccine.
  • Adverse events that are listed in the VAERS Table of Reportable Events Following Vaccination that occur within the specified time period after vaccination.

And keep in mind that VAERS isn’t the only way that the safety of vaccines is monitored, which should be reassuring to those who believe that vaccine reactions are under-reported. And remember that VAERS’ reports did help us quickly find the problems with the older rotavirus vaccines (increased risk of intussusception).

Vaccine Injuries

Vaccine injuries are much less common than you would expect if you listen to the many vaccine injury stories that are posted on the Internet.
