Introducing Fluenz Tetra Key facts Fluenz Tetra is indicated for the prophylaxis of Annual strains: influenza in children and adolescents from 24 months The WHO recommends that the quadrivalent vaccines to less than 18 years of age.1 The use of Fluenz Tetra for use in the 2020-2021 northern hemisphere should be based on official recommendations.1 influenza season contain the following:4 Fluenz Tetra is administered as a spray directly into • A/Guangdong-Maonan/SWL1536/2019 (H1N1) the nose of the recipient (once in each nostril).1 For pdm09-like virus* further administration information, please refer to the • A/Hong Kong/2671/2019 (H3N2)-like virus Summary of Product Characteristics and also the resources on www.fluenztetra.co.uk. • B/Washington/02/2019 (B/Victoria lineage)-like virus Fluenz Tetra is a live attenuated intranasal influenza • B/Phuket/3073/2013 (B/Yamagata lineage)-like virus (flu) vaccine.1 Attenuated means that the live flu virus strains in Fluenz Tetra are weakened – they are also cold-adapted and temperature-sensitive.1,2 This means that the viruses are adapted to cold so that they multiply in the lower temperatures in the nasopharynx to induce protective immunity.1-3 *The H1N1 strain in this year’s vaccine is: A/Hawaii/66/2019 MEDI 326775 (confirmed as an A/Guangdong-Maonan/SWL1536/2019 pdm09-like virus)1 which complies with the WHO recommendation (Northern Hemisphere) and EU decision for 2020/21 season4,5 References 1.

This analysis indicates that the gelatine is so degraded Flu antivirals may potentially affect the efficacy of the that the original source cannot be identified.3 vaccine.1 Therefore, the vaccine should not be administered until at least 48 hours after flu antivirals are stopped.1 Flu Some faith groups accept the use of porcine gelatine antivirals may also affect the response to the vaccine if in medical products2 – the decision is, of course, up taken in the two weeks following vaccination.1 to the parents or guardians of your patient.

Vaccine effectiveness Fluenz Tetra tolerability Due to the changing nature of influenza viruses, WHO Fluenz Tetra was licensed based on trivalent Fluenz monitors their epidemiology worldwide and makes vaccine tolerability data.5 The tolerability for Fluenz is recommendations on the strains to be included for the relevant to Fluenz Tetra because both use the same forthcoming winter (for both the northern and southern manufacturing process. The only difference between hemispheres).1,2 Influenza vaccines are then them is the addition of a fourth influenza strain manufactured using virus strains which are in (a second B strain) to Fluenz Tetra.5 line with these recommendations.1,3 In clinical studies, the tolerability profile of Fluenz Tetra The effectiveness of flu vaccines varies from year to was similar to that of Fluenz.5 Safety data regarding the year, depending on variables such as the closeness use of Fluenz Tetra are based on data from Fluenz Tetra of the match between the composition of a vaccine clinical studies in 2,231 children and adolescents 2 to and the circulating strains, the type of vaccine and 17 years of age, Fluenz clinical studies in over 29,000 the age of the individual being vaccinated.1 children and adolescents 2 to 17 years of age and Fluenz post-authorisation safety studies in over 84,000 Detailed information on the vaccine effectiveness children and adolescents 2 to 17 years of age.5 of Fluenz Tetra can be found here: Additional experience has occurred with marketed https://www.gov.uk/government/publications/ use of Fluenz.5 influenza-vaccine-effectiveness-seasonal-estimates.

The importance of vaccination against flu Why vaccinate children? Seasonal flu has an annual incident rate estimated at The highest rates of GP consultations for 5%–10% in adults and 20%–30% in children, globally.1 Influenza A were seen in children
What are the 2020-2021 uptake targets? NHS England is aiming to increase vaccine uptake rates, to a target of at least 75% in eligible pre-school children, and at least 75% in eligible school-aged children.*1 *There may be some variance across the UK within the other devolved nations: please check the respective communications for Wales, Northern Ireland and Scotland.
