Herpes zoster is caused by the same virus (varicella) that causes chickenpox in children. When this virus becomes active again, it can cause herpes zoster, or shingles. Inactivated zoster vaccine helps prevent shingles.

This vaccine works by exposing you to a small dose of inactive virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Inactivated zoster vaccine is used to prevent herpes zoster virus (shingles):

• in people age 50 and older, including people who previously received a live zoster vaccine (Zostavax); and

• in people 18 years and older at increased risk of herpes zoster virus (shingles) due to a weak immune system.

Inactivated zoster vaccine will not treat chickenpox, shingles, or nerve pain caused by shingles (post-herpetic neuralgia).

Inactivated zoster vaccine may also be used for purposes not listed in this medication guide.

You should not receive the second shot if you had a life-threatening allergic reaction after the first shot.

Inactivated zoster vaccine is given as an injection (shot) into a muscle. A healthcare provider will give you this injection.

This vaccine is usually given in a series of 2 shots:

• the second shot may be given any time within 2 to 6 months after the first shot.

• for people who have a weak immune system, the second shot may be given any time within 1 to 2 months after the first shot.

You may receive this vaccine at the same time that you get a flu shot.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Keep track of any and all side effects you have after receiving inactivated zoster vaccine. When you receive the second shot, tell the doctor if the first shot caused any side effects.

Becoming infected with shingles is much more dangerous to your health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Some people receiving this vaccine had nervous system problems within 42 days after receiving this vaccine, but the risk of this side effect is very low. Seek medical attention right away if you have:

• problems with balance or eye movement; or

• loss of bladder or bowel control.

Call your doctor at once if you have a high fever.

Common side effects include:

• headache, muscle pain;

• feeling tired;
