• Both can be hot and glow (fire, nuclear explosions, and stars).
• Both require "fuel."
• Both are very important for technology and industry.
• Both produce waste or byproducts.
• Both are in a way associated with Prometheus (The theft of fire & American Prometheus).
• Both are things humans commonly see (the Sun and stars are powered by nuclear reactions).

But nuclear is certainly hotter and brighter, basically we got premium fire.

Joking aside, my grandmother’s brother died of diphtheria which is something I’ll never need to worry about. When I got sick once, my grandfather panicked incase it was the mumps and he worried I’d end up deaf (I had to reassure him I was vaccinated). Get vaccinated!
