It doesn’t matter how many people are high-risk each year. We know that high-risk people have to get vaccinated, but (A) doesn’t prove that they need a new vaccine for a different strain every year.

The chance of a serious flu epidemic in a given year doesn't tell us if the most common strain one year will be different from previous years. (B) doesn’t prove that high-risk people need a new vaccine for a different strain each year.

The argument already established that that each year’s vaccine will protect only against the strain that’s most likely to be common that year. Since it doesn’t show that the most common strain will be different each year, (C) doesn’t prove that high-risk people need a new vaccine each year.

Each year’s vaccine only protects against the strain that’s deemed most likely to be common that year. If the strain that’s deemed most likely to be common is different each year, this guarantees the conclusion that high-risk people need a new vaccine for a different strain each year.

The amount of side effects from any given vaccine doesn’t prove that high-risk people need a new vaccine for a different strain of the flu each year. (E) fails to establish that the strain that’s deemed most likely to be common will be different each year.
