季節性流感不論是在南半球還是在北半球，都是一位讓人害怕的常客，因為流感病毒具有高度的變異性，導致每年都需要變更當年度接種的流感疫苗，但由於疫苗製作費時且價格不菲，又常常聽到疾病管制局或是國外世界衛生組織發表目前所接種的疫苗與流行的病毒株不相符，或是明明接種疫苗與流行病毒相符合，但卻仍然發生為數眾多的民眾受到感染。
本研究提出一個以代理人系統為基礎，結合隨機網路、正規網路、小世界網路、無尺度網路、具有群聚性的無尺度網路等網路模型，並使用免疫概念來建構一個流行病傳播模型。在模型中考慮到了高群聚性、低分隔度、節點分支度呈現冪次律分布等真實社會網路所具有的拓樸特性，並透過代理人模擬現實社會中的人類個體，以代理人間的互動代替現實生活中的相互接觸、傳染，從而實現多種病毒株在人類社會中演化、散播的情況，以便了解流感病毒株如何在人類體內與疫苗產生交互影響，從而顯現出疫苗的真實功效，避免疫苗接種流於形式，對於實際防疫工作無應有之功效。

No matter in the Northern Hemisphere or in the Southern Hemisphere,Seasonal influenza is an emerging of infections disease that people fears so much.Because of Influenza virus having higher variability that making it necessary to change the vaccination of inoculating every year .But it is time-consuming and sumptuous to manufacture vaccination. And usually to hear about CDC or WHO publishing the vaccination which we inoculate were not tally with Influenza virus and prevalent among now .Even it is correspond with vaccination and Influenza virus. There are numbers of people be infected with Seasonal influenza.

Our research presents a network model base on agent based model combine with random , regular, small world , scale-free and power law cluster network. We consider the high clustering, low degree of separation and degree present to power law which have topologic characteristics in real social network. Using an agent simulate an individual in real society.We use the interaction of multi-agent to replace the contact of real life , and the situation of multi-virus evolve and spread in human society . Therefore, we can how the real effection of the vaccine is , and avoid invalid of the vaccine.
