回复: 为什么加拿大的感冒如此猛烈
打那个flu shot不是让自己免疫力不工作了吗?那抵抗力不是更差了?
不是,打那个是保护你不中那几个最凶险的病毒的招,那些病毒可以是致命的,对有些人来说。
你的免疫系统是要强健的身体和好的生活饮食等习惯来强大的,而不是靠多生病来的,多生病只能对已得的病毒免疫,而病毒是会变异的。这些shot也是靠你自身的免疫系统来作用的。
The flu vaccine gives your body parts of inactivated flu viruses. These virus parts correspond to parts of proteins floating around in your body. When the virus part contacts a chemical 'match', it stimulates the body to produce the cells and antibodies that can remove this particular intruder. Antibodies are proteins that float in body fluids and can bind to specific chemical markers. When an antibody binds to a substance, it essentially marks it for destruction by other cells. However, an antibody for one type of flu won't necessarily bind to a virus part from another type of flu. You don't get protection against other viruses. A flu vaccine can only stimulate your immune system to protect you against the viruses in the vaccine, with some lesser protection against very similar ones.
