Zoster (shingles)
Vaccine-related information and recommendations Back to top
To whom should shingles vaccine be given?
A single dose of zoster vaccine is recommended for adults age 60 years and older whether or not they report a prior episode of herpes zoster. Persons with chronic medical conditions may be vaccinated unless a contraindication or precaution exists for their condition. For a copy of the ACIP recommendations on zoster vaccine, go to www.cdc.gov/mmwr/PDF/rr/rr57e0515.pdf
What do you think about giving zoster vaccine to nursing home patients? Should healthcare personnel in nursing homes be tested to see if they have had chickenpox before taking care of someone who has received zoster vaccine?
Zoster vaccine can be administered to anyone age 60 years and older regardless of where they reside, unless they have a contraindication to vaccination. All healthcare personnel should ensure they are immune to varicella regardless of the setting in which they work and regardless of their patients' receipt of zoster vaccine.
Can I give our long-term care residents zoster, injectable influenza, and pneumococcal vaccines on the same day?
Yes. Here are the general rules: (1) all vaccines used for routine vaccination in the United States can be given on the same day; (2) an inactivated vaccine can be administered either on the same day as or at any time before or after another inactivated or a live vaccine; and (3) any 2 LIVE vaccines that are not given on the same day must be spaced at least 4 weeks apart. Zostavax is a live, attenuated vaccine; injectable trivalent influenza vaccine (TIV) and pneumococcal polysaccharide vaccine (PPSV) are inactivated vaccines. Therefore, these 3 vaccines can be given on the same day or at any time before or after each other. They cannot, however, be given in the same syringe.
 
Is there an upper age limit for receipt of the zoster vaccine? Local providers are reluctant to give zoster vaccine to persons age 80-plus years.
There is no upper age limit for zoster vaccine. The incidence of herpes zoster increases with age. It is known that about 50% of persons living until age 85 years will develop zoster.
 
Can you give zoster vaccine to persons younger than age 60?
FDA has licensed the vaccine only for persons age 60 years and older. CDC does not recommend off-label use of zoster vaccine among persons younger than 60 years.
 
If we inadvertently give a 12-year-old child Zostavax instead of Varivax, what should we do?
This is a serious vaccine administration error. The event should be documented and procedures put in place to prevent this from happening again. Zostavax vaccine contains about 14 times as much varicella vaccine virus as Varivax.
 
We accidentally gave a 47-year-old healthcare worker Zostavax instead of Varivax for work. Does this count?
Yes, but this is a serious vaccine administration error because Zostavax vaccine contains about 14 times as much varicella vaccine virus as Varivax. You should document the event and establish procedures to prevent this from happening again. The dose of zoster vaccine can be counted as the first of two doses of varicella vaccine for an adult who is not immune to varicella. The second dose of varicella vaccine should be given 4 to 8 weeks after the first dose.
 
I understand that Varivax, ProQuad, and Zostavax each have different concentrations of antigen. Would you tell me how they are different?
A dose of Varivax has 1,350 plaque forming units (PFUs), ProQuad contains 9,800 PFUs (7 times higher than Varivax), and Zostavax contains 19,400 PFUs (14 times higher than Varivax).
 
A 60-year-old patient was given varicella vaccine instead of zoster vaccine. Should the patient still be given the zoster vaccine? If so, how long an interval should occur between the 2 doses?
ACIP states the following: "If a provider mistakenly administers varicella vaccine to a person for whom zoster vaccine is indicated, no specific safety concerns exist, but the dose should not be considered valid and the patient should be administered a dose of zoster vaccine during that same visit. If the error is not immediately detected, a dose of zoster vaccine should be administered as soon as possible but not within 28 days of the varicella vaccine dose to prevent potential interference of 2 doses of live attenuated virus." Avoid such errors by checking the vial label 3 times to make sure you're administering the product you intended!

How effective is the new Zostavax vaccine in preventing shingles?
PIn clinical trials, vaccine recipients had a 51% reduction in shingles, less severe illness when shingles did occur, and 66.5% less postherpetic neuralgia, compared with placebo recipients. During these trials, no significant safety issues were identified.
Will administering Zostavax prevent postherpetic neuralgia (PHN)?
In pre-licensure trials, Zostavax was 66.5% effective in preventing PHN. It is also believed to lessen the severity of both shingles and PHN if a person should happened to acquire the disease after vaccination.
Disease-related issues Back to top
Can you catch shingles from a person with active shingles infection?
Shingles cannot be passed from one person to another through sneezing, coughing, or casual contact. If a person who has never had chickenpox or been vaccinated against chickenpox comes in direct contact with a shingles rash, the virus could be transmitted to the susceptible person. The exposed person would develop chickenpox, not shingles.
When administering zoster vaccine, is it necessary to ask patients if they have ever had chickenpox or shingles?
No. All persons age 60 years or older-whether they have a history of chickenpox or shingles or not-should be given zoster vaccine unless they have a medical contraindication. Medical contraindications are described in detail in the recently released CDC recommendations "Prevention of Herpes Zoster." To obtain a copy, go to www.cdc.gov/mmwr/pdf/rr/rr5705.pdf

Should people who haven't had chickenpox be vaccinated with zoster vaccine?
Serologic surveys indicate that almost everyone born in the United States before 1980 has had chickenpox. As a result, there is no need to ask patients age 60 years and older for their varicella disease history or to conduct lab tests for serologic evidence of prior varicella disease. A person age 60 years or older who has no medical contraindications, is eligible for zoster vaccine regardless of their memory of having had chickenpox.

Can someone who has experienced an episode of shingles be vaccinated with the zoster vaccine?
Yes. Shingles vaccine is routinely recommended for all persons age 60 years and older who do not have contraindications.

How soon after experiencing a case of shingles can a person age 60 years or older receive zoster vaccine?
The general guideline for any vaccine is to wait until the acute stage of the illness is over and symptoms abate.
Precautions & contraindications Back to top
Can we give zoster vaccine to elderly patients who have cancer or an immunosuppressed condition?
No. Zoster vaccine is contraindicated in persons with primary or acquired immunodeficiency.

If an adult has had zoster with herpetic neuralgia ophthalmic complications, when can they receive the zoster vaccine?

Once they are no longer acutely ill, they can be vaccinated with zoster vaccine. There is no evidence that the vaccine will have therapeutic effect for a person with existing postherpetic neuralgia.
How long should we wait before giving zoster vaccine to a patient who has had a blood transfusion?
There is no waiting period for administering zoster vaccine following transfusion. Studies have shown the efficacy of zoster vaccine in patients receiving blood products. The amount of antigen in zoster vaccine is so substantial that it overpowers any antibody to herpes zoster that may be in the blood product. This is not the case for varicella and MMR vaccines, however. Wait 3 or more months before administering these vaccines to a patient who has received an antibody-containing blood product.
When can a patient previously on immunosuppressive chemotherapy receive zoster vaccine?
If the patient was on anticancer therapy, wait 3 months. If they were on high-dose steroids, isoantibodies, immune-mediators, immunomodulators, wait 1 month. Lastly, if they were on low doses of methotrexate, azathioprine, or 6-mercaptopurine, waiting is not indicated as these are not considered immunosuppressive. See the ACIP recommendations for zoster at www.cdc.gov/mmwr/pdf/rr/rr5705.pdf for details.
Should a healthy person age 60 years or older receive zoster vaccine if they are going to be in contact with an unvaccinated infant or an immunocompromised person?
Neither situation is a contraindication to zoster vaccination. A person who gets vaccinated with zoster vaccine who has close household or occupational contact with people who are at risk for developing severe varicella or zoster infection need not take any precautions after receiving zoster vaccine. The only exception is in the rare instance when a person develops a varicella-like rash after receiving zoster vaccine. A vaccine rash is expected to occur less frequently after zoster vaccine is given than after varicella vaccine is given. If a rash develops, the vaccinated person should restrict contact with an immunocompromised person if the immunocompromised person is susceptible to varicella.
Administering vaccine Back to top
How is Zostavax administered?
The vaccine is administered subcutaneously. Reconstitute using the diluent provided and administer it immediately after reconstitution to minimize loss of potency. If the vaccine is not administered within 30 minutes, it must be discarded.
When reconstituted, the volume of zoster vaccine is 0.65 mL. Should 0.65 mL or 0.5 mL be administered to the patient?

The recommended dose for zoster vaccine is the fully reconstituted amount, 0.65 mL.

Vaccine storage & handling Back to top
How should Zostavax be stored?
Zostavax must be stored like varicella vaccine, frozen at an average temperature of 5°F (-15°C) or colder until it is reconstituted. Any freezer that has a separate sealed freezer door and reliably maintains an average temperature of 5°F or colder is acceptable for storage. The diluent should be stored separately at room temperature or in the refrigerator.
People are picking up zoster vaccine at local pharmacies and transporting it to the physician's office to be given. Should this vaccine be given?
Zoster vaccine must be stored at freezer temperature at all times. If the vaccine has been out of the freezer for more than 30 minutes, it should not be used unless a state health department or Merck has authorized its use.
