Immunity black outline icon

About the Immunity black outline icon

A pointed shield holds a thick medical cross in its upper half, while a round virus cell with spike proteins and internal dots overlaps its lower edge. The pairing reads as the body's defense holding an infection back, covering immunity, prevention and medical protection. Use it on vaccination pages, pharmacy and supplement listings, health insurance sites, clinic dashboards and public health campaign material.

The virus sits deliberately in front of the shield so the two shapes interlock rather than stack, which keeps the composition compact and centered. Spike ends are drawn as small open circles for contrast with the solid cross. Pair it with vaccine, antibody and hand washing icons, and use 40 px or more so the spikes stay distinct.

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.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
