CEPI establishes global network of laboratories to centralise assessment of COVID-19 vaccine candidates
- Five laboratories initially selected to work together as part of centralised network to reliably assess and compare immunological responses generated by COVID-19 vaccine candidates
- Global group will minimise variation between individual lab analyses to enable uniform way of evaluating and identifying the most successful candidates
- All COVID-19 vaccine developers (both CEPI-funded and non-CEPI funded) can use the network
2 October 2020, Oslo, Norway –The Coalition for Epidemic Preparedness Innovations (CEPI) has today announced partnerships with five clinical sample testing laboratories to create a centralised global network to reliably assess and compare the immunological responses generated by COVID-19 vaccine candidates. Located across multiple regions globally, the laboratories initially selected for this vaccine-assessment network are: Nexelis (Canada) and Public Health England (PHE, UK), VisMederi Srl (Italy), Viroclinics-DDL (The Netherlands), icddr,b (formerly International Centre for Diarrhoeal Disease Research, Bangladesh), and Translational Health Sciences and Technological Institute (THSTI, India). The network will use the same testing reagents—originating in the labs of Nexelis and PHE—and follow common protocols to measure the immunogenicity of multiple COVID-19 vaccine candidates (both CEPI-funded and non-CEPI funded developers). This approach will ensure uniformity in assessment and informed identification of the most promising vaccine candidates. CEPI is actively negotiating with additional laboratories to participate in this network.
Advantages of centralising immunological response assessment
Typically, the immunogenicity of potential candidate vaccines is assessed through individual laboratory analyses, aiming to determine whether biomarkers of immune response—such as antibodies and T-cell responses—are produced after clinical trial volunteers receive a dose(s) of a vaccine candidate. However, with over 320 vaccine candidates against COVID-19 currently in development, there are likely to be numerous differences in data collection and evaluation methods. This includes potential variation in the range of correlates of immunity being measured by laboratories. Technical differences in how and where samples are collected, transported and stored can also occur, impacting the quality and usefulness of the data produced and making comparisons between measurements in individual laboratories difficult. In addition, with the wide range of COVID-19 vaccine approaches and technologies currently being deployed (e.g., recombinant viral vectors, live attenuated vaccines, recombinant proteins and nucleic acids), standard evaluation of the true potential of these vaccine formulations becomes very complex.
Through centralising the analysis of samples obtained from trials of COVID-19 vaccine candidates, the new clinical-sample-testing network will minimise variation in results obtained, which could otherwise arise due to such technical differences when carrying out independent analysis. The samples from participating vaccine developers will instead be tested in the same group of laboratories using the same methods, therefore, removing much of the inter-laboratory variability and allowing for head-to-head comparisons of immune responses induced by multiple vaccine candidates.
Supporting global COVID-19 vaccine development
Through this new network, up to the limit of programme funding, eligible COVID-19 vaccine developers (both CEPI-funded and non-CEPI funded developers) can use the laboratories, without per sample charges, to analyse the immune response elicited by their COVID-19 vaccine candidates in preclinical, Phase I and Phase IIa studies. Data obtained on the immunogenicity of CEPI-funded vaccine candidates will be used to inform and advance CEPI’s COVID-19 vaccine portfolio by providing quick and accurate evaluation of its candidate vaccines.
By opening the sample testing network to other COVID-19 vaccine programmes, CEPI also aims to ensure that all eligible developers—regardless of their size—can benefit from this analysis. Certain commitments may be required for eligibility, such as making timely publication of sample testing results and sharing data that will be produced on the immunogenicity of COVID-19 vaccine candidates to facilitate future regulatory decisions. The number of samples available for testing per developer may be limited depending on response.
Dr. Richard Hatchett, CEO of CEPI, said: “Encouraging data is now emerging on multiple COVID-19 vaccine candidates, however, there is no way to draw direct comparisons, as different labs may use different measurements to infer immune response.”
“The establishment of CEPI’s centralised laboratory network is the first time a project has been done—at such speed and scale—in response to a pandemic. Our network of labs will operate as though vaccines are all being tested under one roof, to speed up assessment and identify successful vaccine candidates so that we move as quickly as possible to reduce the great suffering caused as a result of this global crisis.”
Dr. Melanie Saville, Director of Vaccine R&D at CEPI, said: “With hundreds of COVID-19 vaccines in development around the world, it is essential that we have a system that can reliably evaluate and compare the immune response of candidates currently undergoing testing.”
“The launch of our new centralised lab network seeks to evaluate these vaccines against a common protocol to ensure alignment and information sharing when identifying the most promising candidates.”
“Through such an endeavour, we aim to work towards our ultimate ambition through COVAX to fund and deliver 2 billion doses of successful COVID-19 vaccine by the end of 2021 to help bring an end to the acute phase of this pandemic.”
The establishment of this network is the result of a recent global Call for Proposals, issued by CEPI in early May, to identify and select potential partners to form a centralised group to directly assess multiple COVID- 19 vaccine candidates. Laboratories were selected based on the capacity to perform such studies, the ability to work internationally to harmonise protocols and data, and their record of receiving and handling samples from multiple geographical locations, among other criteria.
CEPI has also opened a new Call for Proposals to extend the assessment to include clinical samples from
late-stage clinical trials (Phase III and beyond). The Call is open to any laboratory worldwide until 4 October 2020.

Dr Benoit Bouche, Nexelis CEO, comments: “This is of great pride for Nexelis to be entrusted by prestigious governmental and non-governmental organisations, such as CEPI, as a referral lab in the evaluation of COVID-19 vaccine candidates and see assays developed in house becoming the international standard all over the world. The fight against COVID-19 requires a collaborative mindset and we will make sure that colleagues working with the labs selected by CEPI are receiving the best possible support from our scientific team to be in a situation to provide highly accurate results.”
Dr. Bassam Hallis, Head of Vaccine Research Groups at PHE Porton Down, adds: “Together with our strategic partner Nexelis, it took us just six months to develop a series of robust and scalable assays needed to evaluate vaccine candidates, when this usually takes eighteen months. This outstanding achievement would not have been possible without the engagement of our talented scientific teams and is proof of the benefit of collaboration between academic sites and private organisations.”
Professor Emanuele Montomoli, Founder and CSO of VisMederi Srl, said: “It is an honour for us to have been selected by CEPI as a reference laboratory for assessment of COVID-19 vaccine candidates. Since the beginning of the outbreak we have spent a lot of time developing and validating assays for COVID-19 vaccine assessment. We really believe that with our support the vaccines manufacturers can accelerate the licensure of vaccines. Collaboration with other laboratories will be strategic to improve the panel of available assays and find a solution to fight the pandemic.”
Davide Molho, DVM CEO Viroclinics-DDL, said: “We are proud to be a central linking pin in CEPI’s global laboratory network and feel honored to support this initiative with a wide array of assay platforms and supply chain expertise. As a leading virology contract research organisation, we have deep knowledge and expertise to support pandemic prevention strategies. In parallel with CEPI’s mission—to accelerate the development of vaccines against emerging infectious diseases—the entire Viroclinics-DDL team feels committed to contribute to this much needed effort.”
Professor John D Clemens, MD, Executive Director at icddr,b, said: “Ensuring that immunological responses to COVID-19 vaccines are measured systematically in a manner that allows valid comparisons of vaccines will be essential to global efforts to identify those vaccines of greatest public health value. We commend CEPI’s efforts to establish a centralised laboratory network, and, as an organisation with decades of experience in evaluating vaccines, we are keen to contribute to the network.”
Dr. Renu Swarup, Secretary of The Department of Biotechnology, Ministry of Science & Technology, Government of India, said: “More than 30 COVID-19 vaccine candidates are being developed in India and are at various stages of clinical development. The Department of Biotechnology, Government of India is supporting efforts for vaccine development and testing. The bioassay laboratory at Translational Health Science and Technology Institute, an autonomous institute of Department of Biotechnology, is being supported by the Ind-CEPI mission of the Indian government, to provide validated assays for vaccine development at par with global standards. It is well-positioned to run comparability studies with other laboratories both nationally and internationally and will form an important part of the global network of centralised laboratories being supported by CEPI.”
Dr. Subeer S. Majumdar, Executive Director, Translational Health Science and Technology Institute (THSTI), said: “Working with CEPI and network labs is a great opportunity for THSTI to showcase and test its capabilities and raise the bar to meet the standards required for regulatory approval of COVID-19 vaccines both in India and abroad. It will be a learning experience that will help us to tackle ongoing and future challenges with harmonised protocols and validated assays.”
Notes to Editors
About the Centralised Lab Network
The clinical sample testing laboratories selected for this collaborative vaccine network are: Nexelis (Canada) and Public Health England (PHE; UK), VisMederi Srl (Italy), Viroclinics-DDL (The Netherlands), icddr,b (formerly International Centre for Diarrhoeal Disease Research Bangladesh), and Translational Health Sciences and Technological Institute (THSTI, India). CEPI is actively negotiating with additional laboratories to participate in this network.
CEPI has approved costs of up to US $16million for this network. All COVID-19 vaccine developers can use this network for free to assess immunogenicity of their vaccine candidate against a common protocol, using clinical samples from preclinical, Phase I and Phase IIa trials. Samples shipment cost and documentation related to the shipment is the vaccine developer’s responsibility.
All the research laboratories now part of the centralised network have track records of being able to run specific tests (ELISA/neutralisation assay/ELISPOT) for vaccine trials for other emerging infectious diseases. The most advanced validated COVID-19 test (assay) was selected and, alongside associated training, the assay protocol was provided to all laboratories involved in the network to perform the same sample analysis. The ELISAs and pseudoneutralisation assay will be provided by Nexelis, with PHE delivering the wild-type neutralisation. Nexelis and PHE will also supply critical reagents (antigens, pseudoparticles and wild-type virus) along with standards and controls to ensure assay combinability across the network. To ensure ongoing accurate assessment, laboratories will be required to assess a standard sample set every six months.
CEPI-funded COVID-19 vaccine developers are encouraged but are not obliged to use the centralised lab network. Results produced by the centralised lab network will be sent back to the COVID-19 vaccine developer – neither CEPI nor the laboratory who assessed the preclinical or clinical samples will own the data.
CEPI has also opened a new Call for Proposals to extend the assessment to include clinical samples from late-stage clinical trials (Phase III and beyond). The Call is open to any laboratory worldwide until 4 October, 2020. Eligibility requirements and application details are available on the CEPI website.
In order to monitor interest and adjust the testing capacity, we are requesting that all COVID-19 vaccine developers interested in using CEPI’s centralised laboratory network complete this short survey. For any COVID-19 vaccine developer ready to submit their samples to the network, please complete our Sample Analysis Request Form.
