Measuring Immunity Against Circulating Influenza Viruses: Randomized Immunogenicity Study Among US Adults Aged 18-64 Years Comparing Two Approved Influenza Vaccines

This study is a randomized immunogenicity study in an enrolled cohort with active surveillance for influenza-like illness (ILI). During this study, participants will be randomly assigned to receive an approved cell culture-based influenza vaccine (Flucelvax) versus a licensed comparator influenza vaccine (Flublok or Fluzone). Blood samples from participants will be collected for measurement of biomarkers of immune response at baseline (visit 1; day 1), post-vaccination (visit 2; day 29), and post-season (visit 3; day 181). Participants will be asked if they wish to also provide saliva specimens at baseline (visit 1; day 1), post-vaccination (visit 2; day 29), and post-season (visit 3; day 181). Serum and peripheral blood mononuclear cells (PBMC) and plasma samples will be isolated from whole blood and tested for biomarkers of vaccine immunogenicity, and duration of antibody responses.
Participants will receive electronic surveys via email or text message weekly asking about changes in health status and new ILI symptoms; those reporting illness may be asked to provide a respiratory swab for laboratory testing for influenza and other respiratory viruses and up to 2 additional blood draws (acute [<10 days after symptom onset] and convalescent [28 days after acute visit if lab-confirmed positive for influenza]).

Author: Choe, Sunho ; Peng, Lin ; Choi, Won Suk ; Lee, Jacob ; Samson, Sandrine ; Shin, Sooyoun ; Kim, Woo Joo ; Ottaviano, Cecilia

Quadrivalent recombinant influenza vaccine (RIV4) is indicated for active immunization against influenza virus in adults (≥18 years) in countries where it is currently registered. This Phase III, parallel, randomized, modified double-blind, active controlled, multi-center study was designed to compare the immunogenicity and safety of single dose intramuscular RIV4 with a locally-licensed quadrivalent-inactivated influenza vaccine (IIV4, Fluarix® quadrivalent) in participants aged ≥18 years during 2021-22 Northern Hemisphere influenza season at three tertiary care centers in South Korea. Participants were randomized (1:1) to receive single dose intramuscular RIV4 or IIV4. All participants were centrally assigned to randomized study intervention using an interactive response technology (IRT). Participants, investigators, and the staff in-charge of the sampling, safety assessment and immunogenicity assays were blinded. The overall mean age of 300 participants who completed the study was 46.1 years. The post-vaccination geometric mean fold-rise of HAI antibodies were 32.0, 13.2, 6.1, and 5.3 in RIV4 group, and 22.3, 8.0, 4.7, and 3.4 in IIV4 group for the A/H1N1, A/H3N2, B/Victoria lineage, and B/Yamagata lineage strains, respectively. Seroconversion in RIV4 was comparable or higher than IIV4. Neither immediate unsolicited AEs were reported within 30 min of vaccination nor SAEs, AESIs nor deaths were reported during the 6-month follow-up. Clinical Trial Registration:ClinicalTrials.gov number - NCT05144945.

Seasonal influenza continues to cause significant morbidity and mortality, particularly for the elderly and immunocompromised. Current licensed influenza vaccines provide only partial protection even for immunocompetent hosts. Vaccine adjuvants can improve the magnitude and breadth of immune responses and there is considerable interest in identifying new adjuvants that can improve immune responses to seasonal influenza vaccines. This phase I, randomized, double-blind trial evaluated the safety and immunogenicity of one dose of 2018/2019 quadrivalent influenza vaccine (either Fluzone® or Flublok®) administered intramuscularly with or without one of two adjuvants (AF03 or Advax-CpG55.2). A total of 241 healthy adults aged 18-45 years were enrolled and randomized to 1 of 6 groups. Groups 1-3 received one dose of Fluzone® QIV 2018/2019 administered alone or with AF03 or Advax-CpG55.2 and Groups 4-6 received one dose of Flublok® QIV 2018/2019 alone or with one of these two adjuvants. All participants received Fluzone® or Flublok® QIV 2019/2020 ninety days later. Primary objectives were to evaluate safety and reactogenicity along with changes in hemagglutinin inhibition (HAI), neuraminidase inhibition (NAI) and neutralizing antibodies to 2018/2019 seasonal influenza antigens, comparing Day 1 and Day 29 titers. Secondary objectives evaluated the impact of adjuvants on immune responses after subsequent doses of unadjuvanted seasonal influenza vaccine and immunologic responses to heterologous influenza H1 and H3 antigens. Overall, the adjuvanted vaccines were safe and generated robust immune responses against both homologous and heterologous strains. Similar responses were seen across all six study arms. Both adjuvants were associated with qualitatively improved immune responses against some strains at varying timepoints, but results were inconsistent. There were no substantial differences in safety or reactogenicity identified between the study groups and all vaccine formulations were well tolerated. In this highly immunologically-experienced cohort, neither AF03 nor Advax-CpG55.2 demonstrated notable benefit when added to the seasonal influenza vaccine. (ClinicalTrials.gov ID# NCT03945825).

Flu vaccine uptake increases 28% in England

There are currently seven licensed flu vaccines available for the 2025 to 2026 season. Tong_stocker via Shutterstock.com. The number of people receiving a flu vaccine across England has increased by over a quarter, as cases of both influenza and Covid-19 start to climb at the start of the viral season. Data from England’s National Health Service (NHS) shows that the flu jab has been administered to 4.3 million people, a 28% rise from 3.36 million who received the vaccine at the same point last year. The vaccination drive comes as the flu season commences. Influenza infections start to uptick around October, with peaks usually coming in December. Vaccines can help protect against the flu and are offered to people every year at higher risk of becoming seriously ill. Caused by the influenza virus, flu is significantly more serious than the common cold, which is caused by a wide range of viruses. The UK Health Security Agency’s (UKHSA’s) latest surveillance data showed that flu positivity increased from 1.9% to 3.3% and Covid-19 positivity in hospital settings increased from 11.7% in the previous week to 12.9%. One of the key changes to this year’s vaccine programme is the switch from quadrivalent (QIV) to trivalent (TIV) vaccines in inactivated influenza vaccines (IIV). The World Health Organization (WHO) recommends the composition of influenza vaccine strains each year based on global virus trends. For the 2025/26 season, WHO recommends the use of the trivalent vaccine for the Northern Hemisphere. This is because the influenza B/Yamagata lineage virus has not been detected worldwide since 2020 and is not predicted to cause future epidemics. GlobalData Strategic Intelligence US Tariffs are shifting - will you react or anticipate? Don’t let policy changes catch you off guard. Stay proactive with real-time data and expert analysis. By GlobalData Learn more about Strategic Intelligence There are currently seven licensed flu vaccines available for the 2025 to 2026 season. CSL Seqirus’ cell-based quadrivalent influenza vaccine, Sanofi’s Vaxigrip, and Viatris’ Influenza vaccine TIV MYL are given to those above six months of age. AstraZeneca’s Fluenz Tetra, a live attenuated influenza vaccine (LAIV), is for those between two and 18 years of age. For adults over 18 years of age, Sanofi’s Supemtek, a recombinant trivalent influenza vaccine, is used. CSL Seqirus’ other adjuvanted trivalent influenza vaccine is licensed for use for adults above 50 years of age. Sanofi’s Efluelda TIV-HD is available to those 60 years of age and over. The NHS offers flu vaccines for everyone aged 65 and over, and for adults 18 to 64 years of age in certain risk groups. The NHS is bracing itself for a busy winter. Regional teams are improving access to the vaccines through mobile vaccination buses, family community drop-in sessions, and, in an NHS first, delivering flu vaccines to two and three-year-olds in community pharmacies. Meanwhile, eligibility for the Covid-19 vaccine changed for this autumn and winter following an update on recommendations by the Joint Committee on Vaccination and Immunisation (JCVI). The committee advises that the vaccines be offered to people aged 75 or over, residents in care homes, or anyone with a weakened immune system. Dr Amanda Doyle, national director for Primary Care and Community Services at NHS England, said : “Vaccination is a crucial part of our efforts to protect the vulnerable and prepare for what we expect to be a very challenging winter, so I’m delighted to see this big increase in the numbers of people getting vaccinated at this stage. “Vaccinations are our best defence against these potentially very dangerous viruses and can genuinely save lives.” Pharmaceutical Technology Excellence Awards - The Benefits of Entering Gain the recognition you deserve!

Sanofi Starts Shipping US Influenza Vaccines for 2024-25

Sanofi has begun shipped its first influenza (flu) vaccines across the U.S. in preparation for the 2024–25 flu season. Following this first shipment, additional shipments of the full Sanofi flu vaccine portfolio will continue through October to healthcare provider offices, pharmacies and other immunizers to support fall immunization campaigns. With over 125 years of heritage in helping protect global public health, Sanofi is a world leader in vaccines, helping to vaccinate more than 500 million people annually. Thomas Grenier, Head of Vaccines, North America, Sanofi said, "Today, we began shipping flu vaccines for the upcoming season, a moment that underscores our long-standing commitment to providing global protection against disease. Getting a flu shot is imperative to not only help protect against flu infection, but also to help reduce the risks of its potentially severe complications, which can lead to hospitalizations, especially in those most vulnerable. Sanofi understands what these populations need out of their flu shots and works tirelessly from start to finish to provide proven and specific solutions." All flu vaccines provided by Sanofi to the US market are trivalent, meaning they offer protection against the current three strains of influenza (two influenza A strains and one influenza B strain). These strains were selected based on a collaborative review of influenza surveillance by the US Food and Drug Administration (FDA), World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), among other public health experts, as the strains most likely to cause illness in the upcoming flu season. Annual flu vaccination is one of the best ways to help protect against flu and its complications. Public health authorities worldwide reiterate their recommendations for eligible people to be vaccinated every year. As one of the largest providers of influenza vaccines to the United States with a range of options, Sanofi meets immunization needs across the lifespan, from children as young as six months of age through adults 65 years of age and older. This year's 2024/25 US influenza season portfolio includes Fluzone High-Dose (Influenza Vaccine), Flublok (Influenza Vaccine) and Fluzone (Influenza Vaccine). Fluzone, Flublok, and Fluzone High-Dose are vaccines indicated for the prevention of disease caused by influenza A and B strains contained in the vaccine. Fluzone is given to people 6 months of age and older. Flublok is given to people 18 years of age and older. Fluzone High-Dose is given to people 65 years of age and older. Fluzone, Flublok, or Fluzone High-Dose should not be given to anyone who has had a severe allergic reaction to any component of the vaccine (including eggs or egg products for Fluzone and Fluzone High-Dose). In addition, Fluzone and Fluzone High-Dose should not be given to anyone who has had a severe allergic reaction after a previous dose of any influenza vaccine.
