*Eligible for funded influenza vaccine.
≠Recommendations for influenza vaccine for children vary between countries. The Advisory Committee on Immunization Practices within the Centres for Disease Control and Prevention in the U.S. recommends annual vaccination for all children aged 6 months to 18 years. Influenza infection rates are generally higher in children. The greatest benefits are seen in vaccinating children at high risk of influenza or its complications. However, healthy children are the major cause of the spread of influenza in the community and vaccination of this population can substantially reduce the spread of influenza and related costs. The Ministry of Health in New Zealand offers free influenza vaccination to children from six months of age who have certain chronic medical conditions.
†The seasonal influenza vaccine is strongly recommended for women who will be pregnant or are pregnant during the influenza season. In 2009 pregnant and post-partum women in Australian and New Zealand were seven times more likely to be admitted to intensive care with 2009 H1N1 influenza than non-pregnant women of child bearing age. This risk increased to 20 times more likely from 20 weeks gestation. Studies have demonstrated that when the influenza vaccine is given to a woman in the late stages of pregnancy the incidence of laboratory confirmed influenza is reduced during the first 6 months of life and hospital admissions for laboratory confirmed influenza are significantly reduced.
Afluria Quad and Influvac Tetra can be given to a pregnant woman.
Afluria Quad, Afluria Quad Junior and Influvac Tetra can be given to people with a known history of egg anaphylaxis.
- Influenza vaccine is administered by intramuscular or deep subcutaneous injection.
- The subcutaneous administration is recommended for people with thrombocytopenia or a bleeding disorder since bleeding may occur following an intramuscular administration.
- Travellers should consider immunisation or re-immunisation prior to travel to the Northern Hemisphere during their influenza season when the influenza vaccine available in New Zealand provides protection against influenza viruses circulating in the Northern Hemisphere.
- Influenza vaccine can be administered to women planning pregnancy and pregnant women in any trimester. Traditionally, the influenza vaccine was offered in the second or third trimester to avoid coincidental association with spontaneous miscarriage or congenital abnormalities.
- Women who are breast feeding can safely have the influenza vaccine. No adverse consequences for a breast feeding infant have been observed following vaccination of lactating women.
- The ideal time to immunise a person having chemotherapy or radiation therapy is prior to onset of treatment. When this is not possible for the current season, influenza vaccination is recommended for children and adults undergoing cancer chemotherapy as soon as the vaccine becomes available. Following cessation of treatment normal immune responses return after about 30 days.
- Specialist advice should be sought regarding influenza vaccination after bone marrow transplantation. Typically these patients commence annual influenza vaccinations from 6 months post-transplant.
- Where a person has a history of Guillain-Barré Syndrome (GBS) occurring within 6 weeks of a previous influenza vaccination the decision to administer the influenza vaccine must be made on an individual basis after careful consideration of the risks and benefits.
- Epidemiological studies have suggested either no increased risk or a possible slight increase in risk of around one case per million adult influenza vaccinations.
- A study in the United Kingdom compared the incidence of GBS following influenza vaccination and following influenza-like illness. The relative incidence of GBS after vaccination was not increased however the risk after influenza-like illness was seven times higher.
- The influenza vaccine can be administered concurrently with other vaccines, including the herpes zoster (shingles) vaccine, pneumococcal vaccines and Tdap, and the National Immunisation Schedule vaccines. Separate syringes and different injection sites should be used.
- The influenza vaccine is packaged in a single-use syringe. Any vaccine contents remaining should be discarded immediately.
The following dosage schedule for is recommended:
- Children aged 6-35 months
- Afluria Quad Junior
- Age 6-35 months 0.25ml 1 or 2* doses
- Adults and children aged 3 years or older
- Afluria Quad or Influvac Tetra
- Age 3-8 years 0.5ml 1 or 2* doses
- ≥ 9 years 0.5ml 1 dose
* Children aged 6 months to under 9 years who have never received an influenza vaccine before should receive two doses four weeks apart, to help improve their immune response. Children in this age group who have received one or more influenza vaccine doses in the past only need one influenza vaccine dose each year.
Zostavax® and annual influenza vaccination
- Annual influenza immunisation is recommended and funded for adults aged 65 years or over.
- One Zostavax® is recommended for adults aged 65 years to under 80 years. This dose is also funded.
- Zostavax® and influenza vaccine can be administered at the same visit.
- Zostavax® is only given as a single dose – it IS NOT administered every year that an eligible adult receives their influenza vaccination.
- PMS systems have been updated to enable dual claiming of Zostavax and influenza vaccination.
Storage and preparation
Store as per the cold chain, between +2°C to +8°C. Protect from light. The expiry date of the vaccine is the last day of the month in the year indicated on the packaging.
For all vaccines, similar to most medications, an extremely rare allergic reaction called ‘anaphylaxis’ can occur. Anaphylaxis after immunisation occurs about 1–3 times in every one million vaccine doses. All vaccinators will have training and equipment to deal with this situation in the unlikely event of it occurring. No other serious responses to the vaccine have been identified.
Influenza vaccine should not be given to:
- Anyone with severe allergy (anaphylaxis) to a previous dose of this vaccine or a component of the vaccine (except egg anaphylaxis).
Influenza immunisation should be postponed for:
- Individuals suffering from a fever over 38°C.
- The presence of a minor infection is not a reason to delay immunisation.
- Influenza immunisation protects around 7–8 pregnant women out of 10 from serious influenza related illness requiring hospital treatment. Around half of infants whose mother had an influenza immunisation during pregnancy are also protected from influenza for up to 6 months after birth.
- Very little information on how effective the influenza vaccine in infants under 2 years of age has been collected. The information collected suggests about 6–7 in 10 infants in this age group will be protected from influenza.
- Influenza immunisation will protect around 6–7 in 10 healthy children under 3 years of age, around 6–7 in 10 healthy children under 16 years of age, and 4–6 in 10 healthy adults from influenza. The influenza vaccine only has a modest reduction in the time healthy adults take off work due to influenza.
- The influenza vaccine has a modest effect, around 30–50%, in preventing influenza in those aged 65 years and over living in the community and can reduce the number of older people needing to be hospitalised with influenza-related illness and complications. Influenza vaccine has also been shown to reduce the risk of influenza-realted pneumonia in older people living in long term care facilities who develop complications related to influenza.
