A new study reveals that viral infections may leave behind hidden damage to the immune system long after symptoms disappear. Researchers found that mice recovering from an acute infection experienced lasting changes to their spleens and weakened immune responses, potentially leaving them more vulnerable to future threats. Surprisingly, prior vaccination completely prevented these harmful changes in the mouse model.
Camundons who won an acute viral infection had their spleen healed and T cells compromised, and only previous vaccination blocked the damage.
