Allergy causes coughing, sneezing, itching, and eczema, etc. These symptoms recrudesce frequently and are hard to be cured. Especially to children, these symptoms may annoy them, spread their attention for listening and learning; oxygen deficiency due to nasal obstruction may even influence the intelligence development.  
Allergy influence children¡¯s life quality negatively and bring large medical costs to family. It is very important to control and reduce their pains. To protect children who have allergy, we shall help them get correct knowledge of allergy to lesson their fear, get appropriate habits in daily life, eating and treatment.
Pharmacotherapy is a good way to control the symptoms of allergy. It could relieve the symptoms quickly and efficiently. However, pharmacotherapy can not really cure allergy. Though current medicines for pharmacotherapy have been developed with fewer side effects, it is not a good idea to take medicine for a lifetime.
Immunotherapy has been applied for one hundred years and recommended by World Health Organization as the only treatment that can affect the natural course of allergic diseases. It may be especially efficient to children due to the developing immune system. However, conventional immunotherapy (subcutaneous immunotherapy) has risks of severe adverse event and has causes several death over the world. It has been forbidden for over 20 years in Britain. 
We care children. To help children who have allergy, we develop allergen vaccine - ¡°Chanllergen¡± applying sublingual immunotherapy. Sublingual immunotherapy has similar efficacy with conventional immunotherapy and has been proved as an extremely safe route. There is no any severe adverse event since ¡°Chanllergen¡± has been launched in China.
We develop ¡°Chanllergen¡± by the children side. No injection means children will be easy to take the vaccine; no interval hospital visit means children will not lose their time to go to school or have fun. The most important thing is the safety, we could help children be health and happy and protect them from allergy onset in a safe way.
