The Truth About Your Child’s Vaccinations

Our pediatric specialists partner with you to keep your kids safe and well. One of the best ways that we can do this is with vaccinations. Vaccines are the best and safest way to protect everyone from many illnesses.

If everyone continues to protect themselves through vaccination, diseases that are preventable by vaccination will be rare. However, when people do not get vaccinated, viruses and bacteria that cause these preventable infections circulate in our communities, resulting in outbreaks of infections.

Immunizations Help Prevent Serious Illness in Children

“Diseases like polio and measles, which are becoming more frequent in the U.S., are causing illness as they infect unvaccinated and nonimmune people. And with some diseases, all it takes is one case to cause an outbreak in a community,” said Andi Shane, MD, MPH, System Medical Director, Infectious Diseases. “Immunizations both keep your child from becoming ill and prevent them from spreading a vaccine-preventable bacteria or virus to others.” The measles virus is one of the most contagious viruses and spreads quickly among people who are not vaccinated. The best way to protect children from experiencing a serious infection is to receive recommended vaccinations when they are available.

Questions parents are asking about vaccinations:

Are vaccines safe?

Yes. Vaccines are some of the safest and most effective defenses against infection.

In the U.S., all vaccines are tested before being recommended for use. Vaccines make the immune system think that it has been exposed to a bacteria or virus by making antibodies. These antibodies provide future protection against illness when exposed to that bacteria or virus.

Should I delay or space out vaccines?

No. It’s important to talk to your child’s doctor about your child’s immunization schedule. Changing the vaccine schedule could mean delaying protection when it may be needed most. Vaccines can be given at the same time as each other safely.

Will giving babies multiple vaccines at one time overload their immune system?

No. Many studies have been done to evaluate the safety of giving a child multiple vaccines. A child’s immune system is exposed to many more antigens (substances that cause your body to have an immune response and create antibodies) in everyday life than those they will receive from vaccines on their immunization schedule.  

Do vaccines cause autism spectrum disorder?

No. Many scientific studies have continued to show that vaccines do not cause Autism Spectrum Disorder. 

Where should I get facts about vaccine safety?

Your child’s pediatrician is your first source of reliable information. They will make sure that you understand the benefits and risks of each immunization. Asking questions can help you make a well-informed decision. View additional information from the American Academy of Pediatrics.
