To study the effect of vaccination on mortality before 2 years of age in a developing country.
Prospective cohort study.
Rural communities in Burkina Faso.
9085 children born in the study area between 1985 and 1993.
Child death rate.
Mortality before 2 years of age was lower in children who had been vaccinated: those vaccinated with BCG only had significantly lower mortality (risk ratio for vaccinated v unvaccinated children 0.37, 95% confidence interval 0.29 to 0.48) as did those vaccinated with diphtheria, tetanus, and pertussis only (0.24, 0.13 to 0.43). The second dose of diphtheria, tetanus, and pertussis was not associated with lower mortality (0.80, 0.58 to 1.12).
Vaccination with diphtheria, tetanus, and pertussis as well as BCG is associated with better survival of children up to 2 years of age.
研究在一个发展中国家接种疫苗对2岁前儿童死亡率的影响。
前瞻性队列研究。
布基纳法索的农村社区。
1985年至1993年在研究地区出生的9085名儿童。
儿童死亡率。
接种疫苗的儿童2岁前死亡率较低:仅接种卡介苗的儿童死亡率显著较低(接种疫苗儿童与未接种疫苗儿童的风险比为0.37,95%置信区间为0.29至0.48),仅接种白喉、破伤风和百日咳疫苗的儿童也是如此(0.24,0.13至0.43)。白喉、破伤风和百日咳疫苗的第二剂与较低死亡率无关(0.80,0.58至1.12)。
接种白喉、破伤风和百日咳疫苗以及卡介苗与2岁以下儿童更好的存活率相关。
