Mortality rates for same-sex married individuals compared with opposite-sex married individuals: potential analytical problems.

tions to address vitamin A deficiency (by increasing frequent low-level vitamin A intakes) together with continued targeted use of high-dose VACs for those who would benefit. However, we would again like to stress that, since VACs are distributed to 1–5-year-old children, they are not relevant to the majority of under 5-year-old deaths (U5MR), which are predominantly in the first few months of life. At most, in some contexts, they might reduce overall U5MR by about 5%. These considerations suggest that there should be higher priorities for use of large-scale programme resources aimed at reducing under-5 child mortality—by all means in contrast to research resources, which are clearly needed.
