The world health organization estimates that 2 million children die each year from vaccine-preventable diseases such as diphtheria , tetanus , and whooping cough .
世界卫生组织估计每年会有2百万儿童死于可以以疫苗预防的疾病，例如白喉、破伤风、百日咳。
Since you are sensitive to the anti - tetanus serum , we will have to give it to you in four doses , at an interval of twenty minutes .
由于你对破伤风抗毒素过敏，我们要分四次注射，每次相隔20分钟.
The root problem is that today 's parents are the first in history with no memory of the maiming and killing caused by polio , tetanus , diphtheria or measles .
Tetanus killed one of her children in infancy ; another is weak from diarrhoea , caused probably by the custom of keeping mother and baby isolated for a month after birth .
破伤风致使其一子夭折；另一子则因腹泻而身体虚弱，可能是因为孩子出生后母子须分隔一月的风俗所导致的。
Most importantly , one-fifth of infants in the world still do not have access to the six key vaccines : against diphtheria , pertussis , polio , measles , tetanus and tuberculosis .
