# Enable Use Adverse Event PT on CIOMS and MedWatch 3500A

Learn how to configure your Vault to display adverse events using the MedDRA Preferred Term on CIOMS I and MedWatch 3500A forms.

## About the Feature

With the 21R1 release, Vault Safety introduced the option to display adverse events using the MedDRA Preferred Term (PT) on CIOMS I and MedWatch 3500A forms. The feature was originally introduced with Support-enablement. In 23R3, the feature is enabled through an Admin Checkbox.

Once enabled, all new CIOMS I and MedWatch 3500A forms will use the MedDRA PT for adverse events. This will not impact previously generated reports, which must be re-generated to take effect.

If Veeva Support previously enabled this feature in your Vault, you do not need to take any action. In your Vault's _Submission and Distribution Settings_, the **Use Adverse Event PT on CIOMS and MedWatch 3500A** checkbox is automatically selected.
