(Concern) Has anyone tried allergy rhinitis injections?

My child's allergy rhinitis, sneezing, and conjunctivitis are severe.

Spring days with pollen flying, hot summer, early autumn

It runs through all four seasons.

Dust mites, pollen, and other allergens were detected in the allergy test.

The private hospital doctor recommends trying an allergy rhinitis injection (Histobulin injection) once.

They say it's more effective if you get it when you're young.

Is there an appropriate age to receive allergy injection?

I'm wondering if anyone has ever received this nasal allergy injection since it's the first time hearing about it.

There is no one around me who has experienced it.

I want to know if it is effective or if there are side effects.
