Overview

Almost everyone is at risk of shingles because they are likely to have been exposed to chickenpox, even if they have no history of clinical chickenpox or chickenpox vaccination. Following chickenpox infection, the virus lies dormant in the nerves near the spine and may re-emerge many years later as shingles. Shingles most commonly affects older adults or people of any age with a weakened immune system.

One dose of Zostavax® is indicated for the prevention of shingles. It can be given to patients who have previously had shingles. 

Since 1 April 2018, one dose of Zostavax is funded for adults aged 65 years. A 'catch-up' programme is available for people aged from 66–80 years inclusively until 31 March 2020. Funded vaccine doses are only available through general practice. 

Zostavax is also available for individuals aged 50–64 years or 81 years or older to purchase through general practice and some pharmacies.

This vaccine contains a weakened form of the varicella-zoster virus, and as a live viral vaccine, is not suitable for some people with medical conditions or who are receiving treatments that affect their immune system. It is important to seek medical advice before receiving this vaccine.

In Depth

Other brands: None

Vaccine type: Live attenuated

Schedule and administration

One dose of Zostavax® is indicated for the prevention of herpes zoster and the painful complications of herpes zoster (shingles). Prevention of shingles prevents acute shingles-related pain and the risk of chronic pain, known as post-herpetic neuralgia. It is not used as treatment during an episode of shingles or to treat post-herpetic neuralgia. Receipt of Zostavax within the 5 years before an episode of shingles may help to reduce the disease severity, i.e. immunisation may make a subsequent episode of shingles less painful or reduce the risk of post-herpetic neuralgia.

A single dose of Zostavax is recommended for adults aged 50 years and older. There is no upper age limit for administration of Zostavax.

There are no recommendations for booster doses of Zostavax at this time.

Eligibility

From 1 April 2018:

There are two distinct Zostavax eligibility groups. The eligibility criteria listed for the 'Standard programme' only applies to adults aged 65 years on/after 1 April 2018. The eligibility criteria for the 'Catch-up programme' only applies to adults aged 66–80 years inclusively on 1 April 2018.

Standard programme

Adults aged 65 years on/after 1 April 2018

  • No age limit for the standard programme
  • No time limit for the standard programme

Catch-up programme

Adults aged 66–80 years inclusively on 1 April 2018

  • Age limit for the catch-up programme
  • Time limit for the catch-up programme
  • Eligible until 31 March 2020 or they turn 81 years of age, whichever comes first

Funded vaccine doses will only be available through general practice.

Zostavax is available for purchase by ineligible adults through general practice and some pharmacies.

Storage and preparation

Store the vaccine and diluent as per cold chain between 2°C to 8°C. Protect from light. 

Administration

Zostavax can be administered to adults:

  • At the same visit as other vaccines, including influenza, pneumococcal, tetanus/diphtheria and other Schedule vaccines. Separate syringes and different injection sites should be used.
  • Whether or not they recall a history of chickenpox disease. Do not do serology to check varicella immunity.
  • If they have had herpes zoster in the past.
  • If they are living with someone who is immunocompromised.

Unlike other live injected vaccines, Zostavax can be administered at any time before or after blood/blood products.

Antiviral medications should be stopped for 24 hours prior to vaccination and for 14 days after vaccination to prevent interference with replication of the live-attenuated vaccine virus.

If Zostavax is not given at the same visit as another live vaccine a 4 week interval between the two live virus vaccines should be observed. However, there are no live viral vaccines indicated for this age group in New Zealand at this time.

Vaccine safety

Zostavax has an excellent safety record since it was introduced in the U.S. in 2006. The vaccine is generally well tolerated. The most common vaccine side effects occur around the injection site, including redness, swelling and/or pain, and headache. Occasionally itching or a rash around the injection site may occur.

Data from ten years of post-marketing adverse events reports submitted to the Merck Sharpe and Dohme global safety database found that more than 9 out of 10 reports were non-serious and local injection site reactions were the most common. Herpes zoster (HZ) cases occurring within two weeks of vaccination were caused by wild-type, not vaccine-type virus. Disseminated HZ was very rare (18 cases reported, <0.1%), and all the cases found to be due to the vaccine-type virus were in immunocompromised patients.

Administration of Zostavax vaccine should be postponed in individuals suffering from a fever over 38°C. The presence of a minor infection is not a reason to delay immunisation.

Zostavax should not be given to:

  • Individuals with current leukaemia, lymphoma, or other bone/marrow/lymphatic neoplasms.
  • Individuals with acquired immune deficiency syndrome (AIDS) or other medical condition causing cellular immunodeficiency.
  • Individuals with tuberculosis (TB).
  • Anyone with severe allergy (anaphylaxis) to a previous dose of herpes zoster virus vaccine or a component of the vaccine.

Specialist advice should be sought for the following groups:

  • Individuals taking immunosuppressive medication or who are recovering from immunosuppressive treatment.
  • Individuals who are HIV-positive.

If there is any doubt about the safety of administering a live attenuated zoster vaccine – DEFER VACCINATION until you obtain more information.

Vaccine effectiveness

The real-life effectiveness of Zostavax, particularly against severe disease and post herpetic neuralgia (PHN), appears to be better than was shown during pre-licensure clinical trials and especially for those older than 70 years.

Three years after introducing a zoster immunisation programme in the UK for adults aged 70 - 79 years, the incidence of shingles fell by a third and the incidence of PHN halved. Among a vaccine-eligible population of 5.5 million people, this is equivalent to 17,000 fewer cases of shingles and 3,300 fewer cases of PHN. The vaccine effectiveness was calculated to be 62% against shingles and 70-88% against PHN in the targeted age group.

Vaccine effectiveness against shingles in individuals vaccinated in their 80s was found to be similar to those vaccinated in their 60s, and declined at a similar rate with time after vaccination across all age groups, according to a US-based study.

Duration of protection

Vaccine effectiveness against shingles incidence was shown to wane quickly within the first three years (from 67.5 to 39.2%), and then waned more gradually to 31.8% by 8 years after vaccination.

Although the duration of protection against shingles incidence declines, vaccine effectiveness against the severe outcomes of shingles, such as PHN and herpes zoster-associated hospitalisation, remained around at least 50% regardless of age and chronic illness.
