Has there ever been a human that has overcome hayfever?

You know I had really bad hayfever when I was younger, every time I stepped outside my eyes would water and turn red and I constantly sneezed. Thankfully I outgrew it by my mid-late teens unfortunately many of my friends still get it really bad. Like Gices said you can take hayfever medicine other than that yeah maybe immunotherapy might work.

Must have been due to some rare mutation. For everyone else, there are pills that you can take to prevent it.

Do you get hayfever?
