Who & When

Knowing which vaccines you need is an important step toward protecting your health and that of your family and friends.  Getting vaccines on time helps prevent illness before you’re exposed.

If you are sick, you may still be able to receive a vaccine, depending on which vaccine you need and the type and severity of your illness. Talk with your health care provider about the vaccines that might be recommended for your age, health status, and lifestyle. To learn about situations in which you should wait to receive a vaccine or shouldn’t receive one, check the Vaccine Information Statement (VIS) for the particular vaccine you need. If you have a chronic health condition, you can find more information in our guide to vaccine recommendations for chronic diseases

Vaccine schedules are designed with you in mind.  They are constructed to be as safe and as convenient as possible, without requiring unnecessary visits to your doctor or health care provider.
