Viruses mutate rapidly, changing their surface antigens.
Some hide inside host cells where antibodies can’t reach.
HIV and herpes can “go dormant,” evading detection.
Others mimic normal body proteins to avoid attack.
Influenza’s constant shape-shifting forces new vaccines yearly.
Some viruses suppress immune signaling to delay response.
They can even hijack immune cells to spread further.
The immune system counters by updating memory and tactics.
It’s an endless evolutionary chess match.
Despite viral tricks, your immune system wins most battles.
