Immunity black outline icon

About the Immunity black outline icon

A rounded shield marked with a check sits beside a spiked virus cell, the shield overlapping the pathogen so it reads as blocked rather than merely present. The pairing communicates immune defense, verified protection and infection prevention. It fits vaccination landing pages, pharmacy and supplement product cards, hospital infection-control signage, health insurance dashboards and antivirus software screens.

The circular frame keeps the two elements balanced: the shield holds the left two-thirds while the virus with its stubby protein spikes and dotted core breaks the right edge. Uniform stroke weight lets it sit next to mask, vaccine syringe and hand-wash icons from the same set. Below 32 px, drop the outer circle so the spikes stay readable.

This is the black outline version of the immunity icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
