Pediatric Vaccines

Talking Points

PHCC’s Pediatric Vaccine Talking Points reference the American Academy of Pediatrics (AAP) as an expert source on pediatric vaccines. Expert sources are evidence-based, scientifically rigorous, and timely. Some of the information in this resource differs from information shared by Health and Human Services (HHS) and the Centers for Disease Control and Prevention (CDC).

About Pediatric Vaccines

1. Following the American Academy of Pediatrics (AAP) schedule of recommended vaccines is the most effective way to protect infants, children, and teens against 16 preventable, potentially serious diseases. 
   • Measles cases in the United States have reached their highest levels in over 30 years. This has happened as measles vaccination rates have fallen over the last several years to levels below the 95% vaccination rate threshold needed to protect communities against measles outbreaks. Measles vaccination is recommended in children ages 12 months and older and in some cases as early as 6 months of age.
   • The 2024-25 flu season has resulted in the highest number of pediatric deaths from the flu over the last 15 years. This has happened as flu vaccination rates have declined in children in the U.S. Vaccination is the best protection against a potentially life-threatening flu infection. Flu vaccination is recommended for everyone 6 months and older.
2. The recommended vaccine schedule begins at birth to protect infants before they are exposed to diseases such as measles, polio, and whooping cough. As children grow, they need to receive additional vaccines to extend their protection against these diseases. 

Safety and Effectiveness

1. Safety: In the United States, vaccines undergo years of careful research and testing before they’re available to the public. Once available, many health experts and organizations continuously monitor vaccines to ensure their ongoing safety and effectiveness. 
   • Thimerosal is appearing more frequently in the news cycle, causing concern among parents and caregivers. There is no scientific evidence that thimerosal is harmful. Nevertheless, thimerosal is not used in any vaccine on the AAP’s childhood vaccination schedule. For more information about thimerosal, visit PHCC’s “Vaccine Development, Safety, and Effectiveness” topic page.
2. Effectiveness: Without vaccines, children and their adult caregivers are at higher risk for the serious side effects of preventable diseases, including disability and death. Among children born between 1994 and 2023, routine childhood vaccinations prevented: 
   • 508 million cases of illness 
   • 32 million hospitalizations 
   • 1.13 million deaths

Side Effects

1. The most common side effects of pediatric vaccines are very minor, such as mild pain and swelling in the area where the shot was given, a low-grade fever, and irritability. 
2. Severe allergic reactions may also occur, but they are very rare. 

Staying on Schedule

1. Document each vaccine your child receives and keep these records in a safe place. Keeping track of your child’s progress within the vaccine schedule helps ensure your child stays healthy. 
   • Additionally, your child may need to show documentation of their vaccines to go to school and after-school activities, travel abroad, and apply for certain jobs.  
2. If you do not have your child’s vaccination records: contact the doctor(s) and/or clinic(s) who have previously given your child vaccines. You can also contact your state’s immunization registry or your child’s school. 
3. If you cannot find your child’s vaccination records: talk to a healthcare provider about the best next steps for keeping your child safe and healthy.
