Scientists discover a hidden danger of viral infections that vaccines may prevent.

What it means

A new study reveals that viral infections can cause lasting damage to the immune system that persists even after the virus is gone. This hidden danger may be preventable by vaccination, suggesting that vaccines have benefits beyond preventing the initial infection. The research highlights a previously unknown long-term risk of common viral illnesses.

Accuracy & sourcesGrounded

The claim is based on a peer-reviewed study reported by Science Daily, a reputable science news outlet. As a primary source (the actual paper), the finding is authoritative about its own results, but the specific details of the immune damage and the extent of vaccine protection would require reading the full study.
