2020 influenza vaccination guidelines

Annual vaccination is the most important measure to prevent influenza and its complications and is recommended for all people aged 6 months and over.

Free vaccines will be available to eligible Queenslanders from mid-April.

Vaccine strains

The 2020 seasonal influenza vaccines for the southern hemisphere include the following strains:

  • an A/Brisbane/02/2018 (H1N1)pdm09-like virus
  • an A/South Australia/34/2019 (H3N2)-like virus
  • a B/Washington/02/2019-like (B/Victoria lineage) virus
  • a B/Phuket/3073/2013-like (B/Yamagata lineage) virus.

Best timing for vaccination

The timing of vaccination should aim to achieve the highest level of protection during the peak of the influenza season. Flu season in Queensland is typically from June to September, with the peak usually in August.

Vaccinating from April provides protection before the peak season takes place. While protection is generally expected to last for the whole season, the best protection against influenza occurs within the first 3 to 4 months following vaccination.

It is never too late to vaccinate since influenza can circulate in the community all year round. Vaccination should continue to be offered as long as influenza viruses are circulating and a valid vaccine (before expiration date) is available.

It is also important to remind people that the vaccine is not immediately effective and it generally takes 10 to 14 days to be fully protected.

Revaccination late in the same year for individuals who have already received a vaccination is not routinely recommended, although not contraindicated. Revaccination may be considered for people travelling to the Northern Hemisphere in late 2020, who were vaccinated in early 2020. An individual's risk factors, risk of disease and current circulating virus strains should be taken into consideration before recommending a second dose. A second dose is not funded under the National Immunisation Program (NIP) and the individual will need to pay for the vaccine and consultation fee, if applicable.

Eligibility for 2020 season influenza vaccines

Influenza vaccines are funded under the National Immunisation Program for the following groups due to their increased risk of complications from influenza:

  • all children from 6 months to less than 5 years of age
  • all adults aged 65 years and older
  • pregnant women
  • all Aboriginal and Torres Strait Islander people aged 6 months and over
  • individuals aged 6 months and older with medical conditions which increase the risk of influenza disease complications (for a full list go to NCIRS Influenza Vaccines Fact Sheet).

All other individuals not included in the categories above can purchase the vaccine from their doctor.

In 2020, all funded influenza vaccines available will be quadrivalent vaccines (QIV) including the adjuvanted (enhanced) influenza vaccine for adults aged 65 years and older.

Only one government-funded influenza vaccine is available for eligible people each year, with the exception of eligible children up to 9 years of age receiving an influenza vaccine for the first time. These children require and are funded for 2 doses, 4 weeks apart.

Age restrictions apply to all vaccine brands (see Vaccine restrictions).

Children

The NIP is providing free influenza vaccine for all children aged 6 months to less than 5 years of age.

Please refer to the additional dosage requirements for children aged 6 months to less than 9 years.

Aboriginal and Torres Strait Islander people

Flu vaccination is strongly recommended in all Aboriginal and Torres Strait Islander people aged 6 months and older, and eligible for the funded vaccine.

Medically at Risk

Vaccinations are strongly recommended for individuals who have certain medical conditions which place them at greater risk of acquiring influenza. A list of these conditions can be found in the Australian Immunisation Handbook Australian Immunisation Handbook

Pregnant women

Pregnant women are strongly recommended to receive influenza vaccine in each pregnancy at any stage of pregnancy. Women who acquire influenza during pregnancy have an increased risk of severe illness. Vaccination protects the mother and their infant/s from influenza in early infancy.

If not already given at an earlier opportunity, influenza vaccine can be given at the same time as the whooping cough vaccine in the second or third trimester (preferably between 20 to 32 weeks). Women should not delay receiving the influenza vaccine so they can have it at the same time as the whooping cough vaccine.

For more information go to Qld Health pregnant women or NCIRS antenatal pertussis vaccination.

People 65 years and older – enhanced quadrivalent vaccine

Vaccination is particularly important for people in this age group as they are at high risk of complications from influenza and have the highest influenza-associated death rates each year.

The quadrivalent influenza vaccine Fluad Quad®, is provided for people aged 65 years and older. It is an adjuvanted (or enhanced) vaccine which is a standard dose flu vaccine with an added adjuvant to help create a stronger immune response to the vaccination. The 2020 vaccine contains the same components as the vaccine provided for other age groups but has the benefit of inducing a greater immune response in older people.

The enhanced quadrivalent influenza vaccine is the best form of protection against flu for older Queenslanders for the following reasons:

  • Older people do not respond as well to standard influenza vaccine as the immune system response decreases with age.
  • The enhanced vaccine is designed specifically to increase the immune system's response to the vaccine, especially against the influenza A/H3N2 strain which is more common and severe in people aged 65 years and older.

Vaccine restrictions

  • There are no influenza vaccines registered for use in any infant under 6 months of age.
  • Afluria Quad® brand is NOT registered for use in any person under 5 years of age.
  • Fluad Quad® is only available for administration to adults ≥ 65 years and older.
  • Vaxigrip Tetra® Fluarix Tetra® and Flu Quadri® can be administered to individuals from 6 months of age.

Dosage and Administration

All influenza vaccines for 2020 are 0.5mL for children and adults. You do not need to halve the dose of any of the influenza vaccines. Details of dosage requirements, including people with specific medical conditions, can be found in the Australian Immunisation Handbook.

Recording vaccines administered

All influenza vaccinations given to children and adults should be reported to the Australian Immunisation Register (AIR). Use your practice software or enter influenza vaccinations onto the AIR encounter screen.

COVID 19 and Influenza

There are currently no vaccines that protect against COVID 19.

Whilst influenza vaccine will not prevent coronavirus infection it can reduce the severity and spread of influenza, which may make a person more susceptible to other respiratory illnesses like coronavirus.
