Now that you have completed your participation in the clinical trial, we still need to wait until the other participants have also completed their part. Once everyone completes the study, your clinical data, combined with everyone else’s, will tell us if the study was successful or not.

These results will help determine what happens next with the study medicine or vaccine. For example, we may continue to research the study medicine or vaccine in future clinical trials. If enough data from the trials support a safe and effective potential new medicine or vaccine, an application will then be submitted to regulatory authorities such as the FDA for review and potential approval for use by patients. This process often takes years.

Pfizer will provide your study doctor with information about your clinical trial’s results when all participants have completed the trial. We also post study results on ClinicalTrials.gov and summaries of the results (also called Clinical Study Report Synopses) on Pfizer.com

Additionally, for certain Pfizer-sponsored clinical trials, “Plain Language Study Results Summaries” can be found by visiting this page on Pfizer.com and using the search function. These are non-technical descriptions of the design and results of our studies started in 2015 and later. The summaries are intended to make the study results more understandable and accessible to a general audience.
