The measles mumps rubella vaccine, also known as the MMR vaccine, seeks to prevent contraction of these deadly diseases and is credited with saving millions of lives worldwide since its release in the early 1960s. The dosage has since been tuned to facilitate even greater results and has now been shown to prevent any case of these diseases. Only 1 in 25,000 and 1 in 40,000 children are thought to acquire a moderate or severe side effect from the vaccination. Given the considerable rarity for such a side effect to occur, it is considerably safer for a child to receive an MMR vaccination than to not receive it.

The answer to which one of the following questions would be most helpful to evaluate the argument drawn above?

Ⓐ How likely is it for an unvaccinated child to contract measles, mumps, or rubella?
Ⓑ How likely is it for a child to contract a disease other than measles, mumps, or rubella?
Ⓒ How many children who receive the MMR vaccination contract diseases other than measles, mumps, or rubella?
Ⓓ How effective is the vaccination in treating demographics other than children, such as adults or senior citizens?
Ⓔ How many children contract a dangerous virus of any variety?
