A quadrivalent entirely egg-free recombinant haemagglutinin vaccine produced in insect cells
Seroconversion rate in the UK every year is around 10% to 20%, and up to 15% develop symptomatic influenza; peak time for cases is December to March and average GP consultation rate is 50-300 cases per 100,000 population per week. While most people will recover, influenza is considered to be potentially responsible for excess winter deaths in most years. Current vaccine effectiveness is estimated at about 59% overall in adults [2].

Feb 22In the US, Sanofi is pressuring CDC experts to support high-dose Fluzone for older adults. At a CDC Advisory Committee on Immunization Practices (ACIP) meeting Sanofi shared years of data showing the Fluzone High-Dose vaccine, which is indicated for people over the age of 65, is more efficacious than a standard influenza vaccine dose. ACIP isn’t expected to vote on new recommendations until the summer [4] .

Trial or other data

Nov 19FDA approval was based on data from a PIII immunogenicity and safety study (NCT03282240), in which Fluzone High-Dose Quadrivalent achieved the primary endpoint of non-inferior immunogenicity compared to two trivalent formulations of Fluzone High-Dose, each containing one of the two influenza B strains recommended for inclusion in the vaccine for the 2017-2018 influenza season. In a secondary endpoint of the trial, each B strain in Fluzone High-Dose Quadrivalent induced a superior immune response compared to the trivalent formulation not containing the corresponding B strain. Rates of local and systemic reactions that occurred following immunization with Fluzone High-Dose Quadrivalent were similar to those induced by trivalent formulations of Fluzone High-Dose. The most common reactions occurring after administration were injection-site pain (41.3%), myalgia (22.7%), headache (14.4%), and malaise (13.2%). Onset usually occurred within the first 3 days after vaccination, and the majority of reactions were resolved within 3 days of vaccination. Results from the study were published in Vaccine in Sept 2019 [1,3].
