The shingles vaccine (Shingrix) is recommended for adults ages 50 or older, even if you: 

• Have had shingles before
• Received an older shingles vaccine called Zostavax (it’s less effective and is no longer given in the United States)
• Don’t recall having had chickenpox

It’s unclear how long you should wait to get the shingles vaccine if you’ve just had shingles. At a minimum. Wait until after all signs of shingles have resolved. Some experts recommend waiting a year.

Don’t get the vaccine if you currently have shingles, are allergic to any components of the vaccine, are pregnant or breastfeeding, or have a history of Gullian-Barre syndrome. For people with certain health conditions — such as those who have specific autoimmune conditions or types of cancer, or are receiving certain types of immunosuppressive treatments — the decision about whether to get the Shingrix vaccine should be made with their health care provider.
