Immunizations, also known as vaccines, help protect people of all ages from serious diseases. They’re especially important for children, whose immune systems are still developing, and for adults, since some vaccines wear off over time and some diseases can become more serious when you’re an adult. Vaccines also help keep everyone healthy because, when more people are vaccinated, it's harder for diseases to spread. This is called "herd immunity."
Some of the diseases that vaccines help prevent include:
Children need several vaccines at different ages. It’s important to follow the recommended schedule for these and other vaccines, so children stay protected:
Adults may need the measles vaccine, as well as shots for seasonal flu, pneumonia, and shingles.
Vaccines are especially important for pregnant women because they help protect both mother and baby from serious infections that can cause complications during pregnancy, labor, and delivery.
Certain vaccines, like the Tdap vaccine, are recommended during pregnancy because the mother’s antibodies pass to the baby, helping protect the newborn in their first few months before they can get vaccinated themselves.
Vaccines are carefully tested for safety. Side effects are usually mild, like a sore arm or fever. The good news is that the benefits of vaccines are much greater than the small risks.
Keep a list of the vaccines you’ve gotten, and make sure you follow the schedule for recommended vaccines. If you’re not sure if you or your child have had all the right vaccines, talk to your doctor. They can help you make sure you’re on track to stay healthy!
