Importance of Vaccines

Top 10 Reasons to Protect Children Through Vaccination

  1. Parents want to do everything possible to make sure their children are healthy and protected from preventable diseases. Vaccination is the best way to do that.
  2. Vaccination protects children from serious illness and complications of vaccine-preventable diseases, which can include amputation of an arm or leg, hospitalization, pneumonia, hearing loss, convulsions, brain damage, and death.
  3. Vaccine-preventable diseases, such as measles, whooping cough, COVID-19, and influenza are still a threat. They continue to infect U.S. children, resulting in hospitalizations and deaths.
  4. Though vaccination has led to a dramatic decline in the number of U.S. cases of several infectious diseases, some, such as measles, are quite common in other countries and are brought to the United States by international travelers. If children are not vaccinated, they could easily get one of these diseases from a traveler or while traveling themselves.
  5. Outbreaks of preventable diseases occur when many parents decide not to vaccinate their children.
  6. Vaccination is safe and effective. All vaccines undergo long and careful reviews by scientists, doctors, and the federal government to make sure they are safe.
  7. Organizations such as the American Academy of Pediatrics, the American Academy of Family Physicians, the American College of Obstetrics and Gynecology, the American College of Nurse-Midwives, the American College of Physicians, the American Academy of Physician Associates, the National Association of Pediatric Nurse Practitioners, and the Centers for Disease Control and Prevention all strongly support protecting children with recommended vaccinations.
  8. Vaccination protects others you care about, including family members, friends, and grandparents.
  9. If children aren’t vaccinated, they can spread disease to other children who are too young to be vaccinated or to people with weakened immune systems, such as transplant recipients and people with cancer. This could result in long-term complications and even death for these vulnerable people.
  10. We all have a public health commitment to our communities to protect each other and each other’s children by vaccinating our own family members.
