# Manage processing for a high number of concurrent vaccine events

# Manage processing for a high number of concurrent vaccine events {#ariaid-title1}

Release version: Yokohama  
Updated January 30, 2025  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Manage multiple parallel queues to help process vaccine events run in a parallel
mode. You can distribute the vaccine queue events process to different nodes rather than
keeping the load on a single node.

## Before you begin

Role required: sn_vaccine_sm.admin

## About this task

You can implement the vaccine queue events process flow in a parallel mode. With
parallel processing, the job creates separate events for each vaccine queue. This
processing helps distribute the events to all active nodes instead of being
processed in a single node.

## Procedure

1. In the navigation filter, enter <kbd class="ph userinput">sys_trigger.list</kbd>.
2. In the Search field, enter <kbd class="ph userinput">*vaccine queue events process</kbd>.
3. Select the vaccine queue events process record.
4. Set the System ID field to Active Nodes.
5. Click Update.  
   This configuration creates multiple sys_trigger records for each node.
