Question

understanding the importance of vaccinations
vaccines are given to children after a long and careful review by scientists, doctors, and health-care professionals. vaccines will involve some discomfort and
may cause pain, redness, or tenderness at the site of
injection, but this is minimal compared to the pain,
discomfort, and trauma of the disease they vaccine
prevent. serious side effects following vaccination, such
as severe allergic reactions, are very rare. the disease
prevention benefits of getting vaccines are much greater
than the possible risks for almost all children.
some diseases that once injured or killed thousands of
children have been eliminated completely, and others are
close to extinction - primarily due to safe and effective
vaccines. polio is one example of the great impact that
vaccines have had in the united states. polio was once
americas most feared disease, causing death and
paralysis across the country, but today, thanks to
vaccination, there are no reports of polio in the united
which statement best summarizes the passage
about vaccinations?
vaccines are very safe and effective
serious side effects of vaccinations are rare
the benefits of vaccinations outweigh the possible
side effects
polio is no longer an issue in the united states
due to vaccinations

Explanation:

The passage emphasizes that while vaccines may have some side - effects (like soreness, redness, etc.), these are mild compared to the risks of the diseases they prevent. It also mentions that serious side - effects are very rare and that the benefits (such as disease prevention, elimination of some diseases) are much greater than the possible side - effects for almost all children. Option C captures this overall idea of weighing benefits against possible side - effects.
Option A only focuses on safety and effectiveness without the comparison aspect. Option B only talks about rare side - effects without considering the benefits. Option D is too specific (only about polio) and does not summarize the general message about vaccines.

Answer:

C. The benefits of vaccinations outweigh the possible side effects
