Yes. The U.S. Food and Drug Administration (FDA) carefully evaluates all vaccines for safety. After a vaccine is approved, the FDA, the Centers for Disease Control and Prevention (CDC), the vaccine maker, and several other agencies watch for any reports of rare or unexpected reactions. Federal law requires health professionals to report any reaction following an immunization to the Vaccine Adverse Events Reporting System (VAERS).
The risk of problems from a disease is much greater than the risk from the vaccine. Whooping cough, for example, still exists in the U.S. This disease can cause a child to have severe breathing problems or seizures. It can lead to a hospital stay or even death.
Immunizations, or vaccines as they're also known, safely and effectively use a small amount of a weakened or killed virus or bacteria or bits of lab-made protein that imitate the virus in order to prevent infection by that same virus or bacteria.
When you get an immunization, you're injected with a weakened form of (or a fragment of) a disease. This triggers your body's immune response, causing it to either produce antibodies to that particular ailment or induce other processes that enhance...
Most side effects from vaccines are minor, if they occur at all.
The area where the shot was given may be sore. And some children may be fussy or get a slight fever. Your doctor or pharmacist can explain the reactions that could occur.
Children who are allergic to eggs may have a reaction to the type of flu vaccine that contains egg protein. If your child has an egg allergy, ask the doctor if your child can still get the flu vaccine.
Serious side effects are very rare. It's much more dangerous to risk getting the diseases than to risk having a serious reaction to the vaccines.
Isn't it dangerous to get more than one vaccine at a time?
No. Combined vaccines have no greater risk for side effects than a single vaccine does.3
Some parents worry about their children getting several vaccines at the same time. They worry that a child's immune system can't handle all those vaccine organisms at the same time.
Getting more than one shot may seem like a lot for a child's body to handle. But babies have billions of immune system cells that are hard at work all the time, fighting the many thousands of germs they're exposed to every day.
More and more vaccines are being combined into a single shot, such as the measles-mumps-rubella shot. This means fewer shots need to be given. Even though the vaccines are combined, each gives the same protection as it would if it were given alone.
