Vaccine safety and performance

Safety and performance are two of the most important factors in the development of a vaccine, and both are priorities of the clinical development process. Vaccines are not a "one size fits all" mechanism, which is why vaccine research, development, and use contain a wide array of checks for safety and performance. Even after a vaccine has been licensed and is in use, monitoring continues in order to ensure that any new information gathered after the product has been licensed is evaluated by experts and shared with the public. These measures include tracking general vaccine safety information, as well as capturing critical information about vaccine efficacy and effectiveness. The issue of vaccine safety also encompasses addressing the common concerns of parents, advocates, and other groups regarding their confidence in the impact of vaccines on children.
