Chicken pox goes dormant in nerve cells then it reactivates after immunity fades (shingles). That's how new generations keep getting it. Now there's a vaccine given to children but the world is still full of us carriers for a long time.
There is a huge number of flu strains out there so that's a different kind of problem. Along with the fact that the immunity provided by a vaccine is not 100% anyway, and often much lower for influenza viruses.
Of course coronaviruses have been around a long time too (many as common colds) without much (any?) success in combating them.

Strictly speaking, the chickenpox vaccine is a live (attenuated) virus, so even the vaccinated will continue carrying it. I was born in the mid 90s, so I am part of the first generation who got the chickenpox vaccine. About 10 years ago I had a small outbreak of shingles, just on part of one hand. It’s weird to think about all the viruses that live inside us without us realizing 99% of the time, until we do.
