Persons who report that they have not had varicella can still receive the zoster vaccine. Laboratory testing to determine if there is evidence of past infection with varicella zoster virus is not necessary. If serologic testing is conducted and there is evidence of varicella susceptibility, the patient should be offered varicella vaccine not zoster vaccine.
Persons with a reported history of zoster can be vaccinated. Repeated zoster has been confirmed in immunocompetent persons, including soon after a previous episode. Although the precise risk for and severity of zoster as a function of time following an earlier episode are unknown, some studies suggest it may be comparable to the risk in persons without a history of zoster.
Furthermore, no laboratory evaluations exist to test for the previous occurrence of zoster, and any reported diagnosis or history might be erroneous. Although the safety and efficacy of zoster vaccine have not been assessed in persons with a history of zoster, different safety concerns are not expected in this group. There are no data to guide the timing of the administration of zoster vaccine after a prior episode of zoster.
The general guideline for any vaccine is to wait until the acute stage of the illness is over and symptoms subside. For people 50 through 59 years old, the risk of getting zoster and having prolonged pain from post-herpetic neuralgia caused by zoster is much lower than for people 60 years old and older. Healthcare providers considering zoster vaccine for certain people 50 through 59 years old should discuss the risks and benefits of vaccination with their patients.
Although the vaccine has short-term efficacy, there have been no long-term studies of vaccine protection in this age group. In people vaccinated at 60 years old or older, vaccine efficacy wanes within the first 5 years after vaccination, and protection beyond 5 years is uncertain.
Therefore, people who receive the vaccine before 60 years old might not be protected when their risks for zoster and its complications are highest.
Also, healthcare providers may want to first consider whether the patients 50 through 59 years old would have poor tolerance to zoster or post-herpetic neuralgia symptoms. For example, if the patient has. No data are available about the effectiveness of zoster vaccine in adults who become immunosuppressed after their vaccination.
Someone with a minor acute illness, such as a cold, may be vaccinated. But anyone with a moderate or severe acute illness should usually wait until they recover before getting the vaccine. This includes anyone with a temperature of Discard any reconstituted vaccine left in the vial. Can pharmacists in all states administer zoster vaccine? According to the American Pharmacist Association, all states allow pharmacists to administer zoster vaccine.
Not all pharmacists provide vaccination services, and of those who do, not all administer zoster vaccine.
It is best to call the pharmacy ahead of time to find out if they have Shingrix to administer to your patients. The vaccine must be administered in the pharmacy. Do NOT instruct the patient to transport the vaccine from the pharmacy back to your office. This could damage the potency of the vaccine. A year-old patient was inadvertently given varicella vaccine instead of Shingrix.
Should the patient still be given Shingrix? If so, how long an interval should occur between the 2 doses? CDC recommends that 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.
Shingrix should be administered at least 8 weeks after receipt of the varicella vaccine. However, if Shingrix is administered less than 8 weeks after the varicella vaccine, it does not need to be repeated. Avoid such errors by checking the vial label 3 times to make sure you're administering the product you intended. If Shingrix is erroneously given to a child for prevention of varicella, the dose is invalid, but is there a waiting period before a valid dose of varicella vaccine can be given?
Is it OK to give a dose of varicella vaccine as soon as the error is discovered? There is no waiting period. The varicella vaccine dose can be given at any time after the Shingrix dose. We inadvertently gave a year-old healthcare worker Shingrix rather than varicella vaccine for work. Does this dose count? The Shingrix vaccine does not count as a vaccination against primary varicella infection chickenpox.
The first varicella vaccine dose can be given at any time after the Shingrix dose. The second dose of varicella vaccine should be given 4 to 8 weeks after the first dose.
You should always check the label 3 times to ensure you are administering the product intended. While giving a dose of Shingrix the syringe came loose from the needle and part of the dose was lost.
Will the patient be protected with this partial dose or does it need to be repeated? A dose less than the full 0.
If the patient is still in the office the dose can be repeated immediately. If the repeat dose cannot be given on the same day CDC recommends that it should be given 4 weeks after the invalid dose. My medical assistant inadvertently administered a 0. The dose did not contain any antigen. When can we administer a properly reconstituted dose? The CDC zoster subject matter experts recommend that in this situation you should wait 4 weeks before giving a repeat dose.
Several doses antigen and diluent of Shingrix were mistakenly stored in our office freezer. One of these doses was administered to a patient. Is this dose valid and if not, when can it be repeated? Any Shingrix, either antigen or diluent, that is exposed to freezing temperature should not be used. If a dose exposed to freezing temperature is given to a patient the dose should be considered invalid and should be repeated 4 weeks after the invalid dose. Storage and Handling Back to top How should Shingrix be stored?
Protect the vials from light. Do not freeze. Vaccine or adjuvant solution that has been frozen must be discarded. If vaccine that was frozen was administered, the dose does not count and should be repeated.
The repeat dose should be administered 4 weeks after the frozen dose. Discard reconstituted vaccine if not used within 6 hours. How should Shingrix be transported to an off-site clinic location? Shingrix is stored at refrigerator temperature. Providers should also review the vaccine package inserts for the specific vaccines being transported.
