Immunizations - Adult Immunizations

Hepatitis A (Hep A)(What is a PDF document?)

This shot protects against hepatitis A disease.

Who should get it?

  • Anyone who will be in close contact with an adopted child from a country that has high rates of hepatitis A needs two doses. This includes household contacts and babysitters. This recommendation only applies for the first 60 days the child is in the United States.6
  • Adults who will be traveling to certain foreign countries need two doses given at least 6 months apart.
  • Adults who have certain risk factors, such as long-term (chronic) liver disease, also need two doses.

Hepatitis B (Hep B)(What is a PDF document?)

This shot protects against hepatitis B disease. Three doses are needed over at least 4 months.

Who should get it?

  • Adults ages 19 to 59 who have diabetes need this shot if they have not had the shot before. This vaccine is optional for adults ages 60 and older who have diabetes and have not had the shot before.
  • Other adults who have not had this vaccine series need this shot when occupation, travel, health condition, or lifestyle increases their risk of exposure.

A hepatitis combination vaccine (Twinrix) is recommended for those who are at risk for both hepatitis A and hepatitis B. This vaccine is approved in the United States only for those 18 years of age or older.


This shot does not necessarily reduce your risk of getting pneumonia, but it can prevent some of the serious complications of pneumonia, such as infection in the bloodstream (bacteremia) or throughout the body (septicemia).

Your doctor can help you choose between the pneumococcal polysaccharide vaccine (Pneumovax, or PPSV)(What is a PDF document?) or the pneumococcal conjugate vaccine (Prevnar, or PCV)(What is a PDF document?).

Who should get it?

  • People ages 65 years and older need both PCV and PPSV.
  • People who are at high risk for pneumococcal infection usually need more than one dose. For example:
    • People ages 2 years to 64 years who have a chronic disease (such as diabetes or heart, lung, or liver disease) need PPSV.
    • People ages 19 to 64 years who have asthma or who smoke cigarettes need PPSV.
    • People ages 19 and older who have immune system problems, cerebrospinal fluid leaks, cochlear implants, no spleen, or a damaged spleen need both PCV and PPSV.
