Vaccines are only given to children after a long and careful review by scientists, doctors, and healthcare 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 diseases these vaccines prevent. Serious side effects following vaccination, such as severe allergic reaction, are very rare. The disease-prevention benefits of getting vaccines are much greater than the possible side effects 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 America’s most feared disease, causing death and paralysis across the country, but today, thanks to vaccination, there are no reports of polio in the United States. – “Five Important Reasons to Vaccinate Your Child,”
