Banana allergy?

Gave my LO some mashed up bananas for the first time a couple days ago. About 2 hours later he was projectile vomiting. After the third time and all being large quantities of throw up in 15 minutes time we decided to go to the ER. They dismissed it being a possible allergy and said it’s probably a virus 🙄 our hospital sucks though. Seeing our normal pediatrician tomorrow but wondering if anyone else’s LO have had this? My little guy was completely back to normal the next morning so I just don’t feel like it was a virus...
