Immunizations for children and Teens

Timely immunizations (also known as “vaccinations”) help to keep your family and the community healthy. Immunizations are a regular part of well-child visits.

Below you’ll find a general list of vaccines that we recommend for children and adults. Some immunizations are given in a single shot, while others require a series of shots over a period of time. Missed doses can often be made up.
