成人免疫至今仍是一个世界性的被人所忽视的大问题。据世界卫生组织统计,世界上每年有成千上万的人因未被免疫而感染疾病,甚至危及生命。美国每年大约有7万人因此而死亡,数10万人因此而罹患各种传染病。美国“联邦疾病控制中心”免疫科主任阿兰·欣曼博士指出:“有史以来,我们一直认为免疫似乎只是儿童的事,实际上,它也是成年人该做的事”。从万年县两种常见传染病的发病情况看,开展成人免疫在我国也是非常重要的。这两种传染病一种是流脑,1985～1986年间曾在万年县发生大流行,其发病率为159.65/10万,发病923人;其中成人发病158人,占总发病人数的17.12％,死亡4例,病死率为2.53％;第二种传染病是肝炎,1986～1987年万年县共发病118人,其中成人发病80人,占总发病人数的67.8％,死亡2人,病死率2.5％。这两种传染病在成人中的发病数占总发病人数的 Adult immunity is still a big problem ignored by the world today. According to the statistics of the World Health Organization, thousands of people in the world are not infected with the disease and are even life-threatening every year because of their immunity. As many as 70,000 people die each year in the United States, and as many as 100,000 people suffer from various infectious diseases. Dr. Alan Hinhinman, director of immunization at the Federal Center for Disease Control in the United States, said: “We have always believed that immunization appears to be only children’s issues. In fact, it is also something adults should do.” From the incidence of two common infectious diseases in Wannian County, it is also very important to carry out adult immunization in our country. One of these two kinds of infectious diseases is meningitis. In 1985 and 1986, there was a pandemic in Wannian County, with a prevalence of 159.65 / 100,000 and 923 persons. Among them, 158 were adults and accounted for 17.12% of the total number of cases. , 4 died, the case fatality rate was 2.53%. The second infectious disease was hepatitis. From 1986 to 1987, 118 people were found in Wannian County, of which 80 were adults, accounting for 67.8% of the total, 2 were dead and dead Rate of 2.5%. The incidence of these two infectious diseases in adults accounts for the total number of cases
