2. Vaccines are safe
As vaccines have progressed, they have become more purified and effective. While they have always been safe, continuous improvements have reduced the amount of side effects, such as high fevers, people endure. Minimal reactions today include some pain, redness and discomfort at the site of the injection. Very rarely do vaccines cause allergic reactions. Even so, the disease an unvaccinated child could come down with is far worse than any possible side effects.
