There are two herpes zoster vaccines. The newer herpes zoster vaccine is preferred over the older herpes zoster vaccine because it provides better and longer-lasting protection.
The newer vaccine contains only noninfective pieces of the virus (called a recombinant vaccine). There is no live virus in this vaccine.
The older vaccine contains live but weakened virus (called a live-attenuated vaccine). It is no longer available for use in the United States.
These vaccines help reduce the risk of shingles Shingles Shingles is a painful skin rash caused by a viral infection that results from reactivation of the varicella-zoster virus, the virus that causes chickenpox.

It can be reactivated years later and cause shingles, which is a painful rash, usually on only one part of the body. The rash resolves after several weeks, but postherpetic neuralgia, which causes severe chronic pain, can last for months or years. Herpes zoster can also cause other problems due to malfunction of the nervous system (such as problems with vision, hearing, or balance).
Administration of Herpes Zoster Vaccine
The newer recombinant herpes zoster vaccine is given in two doses, injected into a muscle. The doses are given 2 to 6 months apart and at least 2 months after the live-attenuated herpes zoster vaccine.
The recombinant vaccine is recommended for people aged 50 and over whether or not they have ever had shingles or have been given the live-attenuated vaccine.
Certain conditions may affect whether and when people are vaccinated (see also CDC: Who Should NOT Get Vaccinated With These Vaccines?). If people have a temporary illness, doctors usually wait to give the vaccine until the illness resolves.
Side Effects of Herpes Zoster Vaccine
The most common side effects of the recombinant vaccine are pain, soreness, redness, and swelling at the injection site and headache, fatigue, muscle pain, shivering, fever, and digestive upset.
The most common side effects of the live-attenuated vaccine are soreness, redness, swelling, and itching at the injection site and headache.
