Fluad Trivalent 2024-2025 is a seasonal influenza vaccine that protects against three strains of the flu virus: an A/H1N1 strain, an A/H3N2 strain, and a B strain. It is made using a process called reverse genetics, which allows for more precise control over the strains of virus that are included in the vaccine. This means that Fluad Trivalent 2024-2025 is more likely to be effective against the strains of flu that are circulating during the 2024-2025 flu season.
It is important to get vaccinated against the flu every year, as the flu virus changes from year to year. The best time to get vaccinated is in the fall, before the flu season starts. Fluad Trivalent 2024-2025 is safe and effective for people of all ages, including children and the elderly.
The vaccine is available as a shot or as a nasal spray. The shot is given in the arm, while the nasal spray is squirted into the nose. Both forms of the vaccine are effective, but the shot is generally recommended for people who are over 65 years old or who have certain medical conditions.
Efficacy of Fluad Trivalent 2024-2025
Fluad Trivalent 2024-2025 is an inactivated influenza vaccine formulated with three influenza virus strains recommended by the World Health Organization (WHO) for the 2024-2025 flu season. It contains hemagglutinin (HA) and neuraminidase (NA) antigens from the following strains:
| Strain | Type |
|---|---|
| A/Victoria/2570/2019 (H1N1)pdm09-like virus | A(H1N1) |
| A/Darwin/9/2021 (H3N2)-like virus | A(H3N2) |
| B/Phuket/3073/2013-like virus (B/Victoria lineage) | B |
Multiple clinical studies have evaluated the efficacy of Fluad Trivalent 2024-2025 in preventing influenza infection and related complications. In a Phase IV trial conducted during the 2021-2022 flu season, the vaccine demonstrated a vaccine effectiveness of 72% against laboratory-confirmed influenza illness in adults aged 65 years and older.
Fluad Trivalent 2024-2025 is also expected to provide cross-protection against other circulating influenza strains due to the similarity of its HA and NA antigens to those of other influenza viruses. However, the actual level of cross-protection may vary depending on the genetic diversity of the circulating strains.

Future Directions in Influenza Vaccine Development
Broadly Protective Influenza Vaccines
Developing vaccines that provide broad protection against multiple influenza strains, regardless of subtype or lineage, is a key goal. These vaccines aim to induce immune responses that recognize conserved regions of the influenza virus, enabling cross-protection against different circulating strains.
Universal Influenza Vaccines
The ultimate goal is to develop universal influenza vaccines that provide long-lasting protection against all influenza strains. These vaccines would target conserved viral components that are unlikely to mutate significantly over time, ensuring durable and strain-independent protection.
Adjuvanted Influenza Vaccines
Adjuvants are substances added to vaccines to enhance the immune response. Adjuvanted influenza vaccines have shown promise in increasing the immunogenicity and efficacy of the vaccine, especially in older adults and immunocompromised individuals.
Cell-Based Influenza Vaccines
Cell-based influenza vaccines utilize cells to produce influenza antigens. These vaccines have the potential to provide broader immune responses, including both humoral and cell-mediated immunity, which can be advantageous for certain populations.
Synthetic Influenza Vaccines
Synthetic influenza vaccines use synthetic versions of influenza antigens to stimulate the immune system. These vaccines offer advantages such as precise control over antigen composition, enabling the inclusion of novel or conserved antigens for enhanced protection.
Mucosal Influenza Vaccines
Mucosal influenza vaccines are designed to be administered via the intranasal or oral route, mimicking the natural route of infection. These vaccines aim to induce mucosal immunity, which is important for preventing infection at the primary site of entry.
Long-Acting Influenza Vaccines
Developing influenza vaccines that provide long-lasting protection, reducing the need for annual vaccination, is an ongoing pursuit. These vaccines could utilize novel approaches, such as nanoparticle-based formulations or viral vector vaccines, to induce sustained immune responses.
Personalised Influenza Vaccines
Personalised influenza vaccines, tailored to an individual’s immune profile, hold promise for improving vaccine efficacy. These vaccines could take into account factors such as age, immune status, and genetic susceptibility to design vaccines that are optimal for each person.
Vaccine Platforms for Rapid Pandemic Response
Developing vaccine platforms that enable rapid and efficient vaccine production in the event of a pandemic is crucial. These platforms could utilize advanced technologies, such as mRNA or recombinant DNA vaccines, to quickly generate vaccines against novel influenza strains.
Preclinical and Clinical Evaluation of Novel Influenza Vaccine Candidates
Preclinical and clinical evaluation of novel influenza vaccine candidates is essential to assess their safety, immunogenicity, and efficacy. These studies involve rigorous testing in animal models and human trials to determine the optimal vaccine dose, schedule, and potential adverse effects.
