ELI5: Why is Chicken Pox so much more deadly in adults rather than children?
gpt
Honestly, we don't know yet.

The current theory is that there's a difference between a child's immune system and an adult's. A child's immune system prefers to eat up bacteria and viruses, while an adult's prefers to shoot bullets at bacteria and viruses (antibodies). Some think that the "eating" method is just more effective against the chicken pox virus.
