Periodo di rendicontazione: 2023-03-01 al 2024-05-31

Sintesi del contesto e degli obiettivi generali del progetto

RBDCOV aims to test the efficacy, tolerability, and safety of the HIPRA vaccine for COVID-19. HIPRA's vaccine is an adjuvanted recombinant protein vaccine, based on a receptor binding domain (RBD) fusion heterodimer against SARS-CoV-2. RBDCOV aims to generate robust data to demonstrate the safety and immunogenicity of this vaccine given as a booster vaccination to induce a higher and more durable immune response, for potential new variants. It should be effective in the prevention of COVID-19.

The initiative is an innovative vaccine-focused research project that brings together the expertise of a number of European organisations and companies.To achieve the project objectives, it is crucial involve as many European stakeholders as possible. That is why the RBDCOV consortium rely on the expertise and the experience of the 12 project partners. The RBDCOV benefits from the perspective of specific populations, i.e. People with immunocompromising conditions, that have been largely excluded from Phase III trials with already authorised SARS-CoV2 vaccines, as vaccine-related immune responsiveness is unclear in this population, who are at higher risk of severe COVID-19.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

During the second reporting period (RP2), the RBDCOV project made substantial progress in testing the efficacy, safety, and tolerability of the HIPRA-developed COVID-19 vaccine (BIMERVAX®) in vulnerable groups. Key milestones included paediatric trials with 350 children and trials for 240 immunosuppressed adults. Manufacturing capabilities were enhanced, and new formulations were developed for emerging variants. Significant regulatory and public engagement efforts were made, positioning the vaccine for broad use and commercialization.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

An ideal COVID-19 vaccine should have high protective efficacy and be safe and deployable for billions of potential vaccinees. To achieve this goal, an optimal vaccine target, platform and dose regimen are important . Therefore, development of a range of COVID-19 vaccines with different mechanisms of action would be beneficial to diversify the global vaccine pipeline.

RBDCOV is an ambitious project that will offer a new tool to control the pandemic at short-medium and long term. RBDCOV aims to manufacture and test the first recombinant protein-based vaccine to be authorised in Europe beyond the framework of the project. The final formulation of RBDCOV vaccine based on the results on safety and efficacy (obtained during the assessment of different formulations, the experience of the company in using highly innovative platforms for vaccine manufacturing in animals and the solid consortium included in the RBDCOV project will make feasible to settle the bases for this challenging objective.
