Why should it be done?
Measles, mumps and rubella are diseases with serious complications:
Measles causes a range of symptoms from ear infection and bronchitis to convulsions (fits) or brain damage, and can be fatal. Mumps used to be the main cause of viral meningitis in children. Also causes temporary deafness, miscarriage, inflammation of the pancreas, and Pain and swelling in the Testicles in older males. Rubella can lead to painful joints, blood disorders and/or swelling of the brain (encephalitis). It damages unborn babies, and may cause miscarriage if the mother catches the disease while pregnant. Babies born with congenital rubella syndrome may have some degree of deafness, blindness, and damaged heart or brain functioning.
There has been some controversy about the MMR vaccine in recent years, owing to a study published in The Lancet in 1998 by Dr Andrew Wakefield. His initial study appeared to show a link between the MMR vaccine and autism and/or bowel disease. But subsequent work and other studies have been unable to prove any association with these conditions.
MMR is the combined vaccine to prevent the following diseases:
measles, mumps, and rubella.
People are not given the MMR vaccine if they: are very ill, have already had a severe reaction to MMR in the past, are pregnant - women should avoid becoming pregnant for one month after having the MMR vaccine, have had an injection of immunoglobulin or another blood product in the previous three months, know that they may react severely to the antibiotic preparations neomycin or kanamycin, or have an untreated malignant disease or altered immunity.
Very few children are unable to have the MMR vaccine for medical reasons.

三联疫苗信息－麻诊，腮腺炎和风疹
为什么要进行疫苗接种呢？
麻诊，腮腺炎和风疹都是有严重并发症的疾病：
麻诊可引起一系列的症状，如耳部感染、支气管炎，甚至惊阙或大脑损伤，有些症状可能是致命的。
腮腺炎曾经是儿童病毒性脑膜炎的主要病因，也可引起一过性耳聋、流产、胰腺炎及成年男子睾丸肿痛。
风疹可引起关节疼痛、血液病和/或脑水肿（脑炎），并且对胎儿有损伤，孕妇在孕期感染风疹可导致流产，先天性风疹综合症的患儿有不同程度的耳聋、失明，以及心脏和大脑功能损伤。
1998年Andrew Wakefield博士在柳叶刀杂志上发表了一项研究报告，他的初步研究表明三联疫苗和自闭症和/或肠道疾病有关联，但是随后研究及其它研究不能证实和这些情况有关，因此近年来有关三联疫苗有颇多争议。
三联疫苗作为一种联合疫苗可以预防以下疾病，
麻诊，
腮腺炎
和风疹
以下情况者疫苗禁止使用：
患有重病
以往有接种三联疫苗重度过敏史，
孕妇（妇女应用三联疫苗后应避孕一个月），
前三个月内注射免疫球蛋白和其它血液制品，
知道会对卡那霉素和新霉素有严重反应，或者患有不能治愈的肿瘤性疾病或者免疫力改变.
因医疗原因，大多数儿童能够接种三联疫苗。
