immunizer

Provides disease protection

An immunizer is something that confers immunity—typically a vaccine or other agent that protects against disease.

The term applies to both the substance administered and, less commonly, the person administering it: Community health workers served as immunizers during the campaign.

In figurative use, anything that renders someone resistant to harm or influence: Experience became her immunizer against disappointment.
