All of this intuitively makes sense, and there is a growing body of scientific evidence to back it up. It has been shown, for example, that vaccinated children not only do better at school, but also that, through the prevention of damage that can be caused by infectious diseases and resulting nutritional imbalances, they appear to benefit in terms of cognitive development.
这一切都非常直观，而支持这一点的科学证据也在与日俱增。比如，我们已经知道，接种儿童不但在学校表现更好，而且由于预防了可能由传染病及其所导致的营养不良所造成的伤害，这些儿童在认知发展方面也会获益良多。
