肺炎是我国5岁以下儿童的主要死因之一。重症肺炎中，约有一半是由肺炎链球菌引起的，肺炎链球菌是5岁以下儿童疫苗可预防死亡的首要病因。

Pneumonia is one of main cause of death among children under 5 years of age in our country.Severe pneumonia in the,About half are caused by streptococcus pneumoniae,Streptococcus pneumoniae vaccine preventable deaths in children under five years old is the primary cause.

　　4月25日全国儿童预防接种日来临之际，中国健康教育中心、中华预防医学会、中华医学会儿科分会共同举办了“爱在百天——中国宝贝健康行动”肺炎链球菌性疾病健康教育与健康传播项目启动仪式。

April 25 national child vaccination day approaching,Centre for health education in China/The Chinese preventive medicine association/Pediatric branch of Chinese medical association jointly held"Love in the one hundred - day Chinese baby health action"Pneumococcal disease health education and health communication project start ceremony.

　　中国疾病预防控制中心流行病学首席专家曾光教授说，目前，肺炎链球菌疾病已经成为全球重要的公共卫生问题，由于其高发病率、高致残率、高死亡率，世界卫生组织已将肺炎链球菌性疾病列为需“极高度优先”使用疫苗预防的疾病。

The Chinese center for disease control and prevention epidemiological chief expert professor zeng guang says,At present,Pneumococcal disease has become an important global public health problem,Because of its high incidence/High morbidity/High mortality rates,The world health organization has ranked pneumococcal disease need to be"Very high priority"Using vaccines to prevent the disease.

　　首都医科大学杨永弘教授特别强调：肺炎链球菌性疾病还可能导致耳聋、瘫痪、智力低下等严重后遗症。肺炎链球菌广泛分布于自然界，可以通过咳嗽或者打喷嚏进行传播并长时间潜伏在人体内，儿童的鼻咽部携带率高于成年人。婴幼儿体内来自母亲因素的抗体保护大约在出生后3至5个月降至最低阶段，自身免疫力水平处于最低水平。因此，在婴幼儿出生后百天左右，需及时和全程接种疫苗预防疾病。肺炎球菌结合疫苗具有良好的免疫原性，接种疫苗是降低肺炎链球菌耐药率的有效手段之一。杨莲清

The capital university of medical sciences professor Yang Yonghong special emphasis:Pneumococcal disease can also lead to deafness/paralysis/Mental retardation severe sequelae.Streptococcus pneumoniae is widely distributed in nature,Can be spread through coughing or sneezing and lurking in the human body for a long time,Children nasal pharyngeal carrying rate is higher than adults.Infants and young children production factors from the mother's antibodies to protect in about 3 to 5 months after birth to minimise phase,Own immunity levels at the lowest level.so,In infants and young children after the birth of around one hundred days,Need timely and full vaccination.Pneumococcal conjugate vaccine has good immunogenicity,Vaccination is one of the effective means of reducing pneumococcal ni.Yang Lianqing
