Vaccine FAQs
Get answers to common vaccine questions.
What is a vaccine or immunization?
A vaccine is a type of medicine that is usually given to you as a shot with a needle. The medicine in the shot protects your body from one or more diseases. When you get this medicine, your body learns how to fight the disease so that you will not get sick from it. This is called “immunization.”
Is there an age restriction for vaccines?
Your doctor can determine if you should receive a vaccine based on CDC recommended guidelines.
Why does my child need vaccinations?
Vaccines help the people who get them because they prevent them from getting diseases or infections that could make them sick or even kill them. They also help the vulnerable, unvaccinated people around them because it reduces the spreading of diseases and infection if most people are vaccinated and are not contracting them in the first place.
Are vaccines safe?
Yes. Vaccines are very safe. If any side effects occur from vaccinations, they are very minor, such as soreness where you received the shot, fussiness; or a low-grade fever. Serious side effects, like allergic reactions, are very rare, and doctors are trained to treat them.
My child doesn’t like shots. Is there another way to get vaccinated?
Some vaccines can be taken by mouth or sprayed into your nose. Talk to your doctor to see whether this is an option. Most of the time, you will need to have the shot with a needle. It may sting for a moment and be a little sore, but it is much better than taking the risk of getting sick. Putting a cool, wet wash cloth where you got your shot can help make it feel better.
Why do we get the same shot more than once?
Some vaccines take more than one dose to give you full protection. Other vaccines stop working after a while, so you need to get them again. Make sure that you get every dose of all of your vaccines. This is the only way to make sure that you are protected from the disease.
Why do vaccinations start so early?
Babies and young children need to be vaccinated because they are more at risk for diseases. These diseases can also be much more serious for infants and young children.
How do I know which vaccines my child needs?
Talk to your child’s doctor about what vaccines they need. You can also look at these charts that tell you what vaccines your child needs based on how old they are.
