Moderna

US mRNA vaccine and medicines company, maker of the Spikevax COVID-19 vaccine.

Moderna's Bundibugyo Ebola vaccine, mRNA-1469, has been in human testing since a volunteer in Truro, Nova Scotia was dosed on 3 August 2026, and CEPI money also carries its Phase 3 H5N1 vaccine trial.

Background

Moderna's outbreak vaccines now share the company's attention with a cancer programme. On 19 August 2026 Moderna and Merck reported that intismeran autogene, an individualised mRNA melanoma therapy, met its primary endpoint in the 1,137-patient Phase 3 INTerpath-001 trial. The trial lead called it the first Phase 3 study to beat Keytruda alone in that setting.

The company was founded in 2010 in Cambridge, Massachusetts, and builds vaccines and medicines on messenger RNA. Stéphane Bancel, formerly head of the French diagnostics firm bioMérieux, has been chief executive since 2011. Its COVID-19 vaccine, Spikevax, was authorised in late 2020 and made Moderna one of two companies to prove mRNA at population scale.

The platform's selling point in an outbreak is speed: an antigen can be updated in weeks rather than the months conventional vaccines need. That is why funders turned to it for both H5N1, where its Phase 3 trial began on 21 April 2026, and Bundibugyo ebolavirus, for which no licensed vaccine or treatment exists.

Key Issues
Pandemic vaccines

Outside money carries Moderna's outbreak vaccines

Moderna's pandemic programmes in 2026 run on CEPI funding. Dosing in the Phase 3 trial of its H5N1 vaccine, mRNA-1018, began on 21 April, the furthest any mRNA H5N1 candidate has gone. When the US Department of Health and Human Services withdrew federal funding, CEPI committed $54.3m in May to keep the trial running.

The same funder backs its Ebola work. CEPI committed up to $50m on 1 June for mRNA-1469, a Bundibugyo candidate, and the first volunteer received it on 3 August in a Phase 1 trial of about 80 adults. That trial measures safety and immune response; protection must be shown later in the field. Oxford's ChAdOx1 vaccine reached people first, on 24 July, while Egypt's Minapharm, funded with up to $16.5m on 27 August, starts behind Moderna.

Common Questions

Outside money carries Moderna's outbreak vaccines

Is Moderna developing an Ebola vaccine?
Yes. A volunteer in Truro, Nova Scotia received Moderna's Bundibugyo vaccine candidate, mRNA-1469, on 3 August 2026 in a Phase 1 trial of about 80 adults. CEPI committed up to $50m to the programme.Source: CEPI
Why did the US government stop funding Moderna's H5N1 trial?
The US Department of Health and Human Services withdrew funding under the Trump administration's cuts to pandemic preparedness programmes in early 2026. CEPI stepped in as the sole sponsor.Source: CEPI
What is Moderna's H5N1 vaccine and how far along is it?
Moderna began dosing the first participants in a Phase 3 H5N1 mRNA trial (mRNA-1018) on 21 April 2026, after CEPI stepped in with $54.3m when US government funding was withdrawn. This is the furthest any H5N1 mRNA candidate has progressed.Source: CEPI

Who is the CEO of Moderna?
Stéphane Bancel has led Moderna as chief executive since October 2011. He previously ran the French diagnostics company bioMérieux.Source: https://www.sec.gov/Archives/edgar/data/1682852/000130817926000081/mrna-20260316.htm
How does Moderna's mRNA platform help with pandemic preparedness?
Once a pathogen's target antigen is sequenced, Moderna can design and manufacture a candidate vaccine in weeks rather than the months required by egg-based or protein-subunit approaches, directly enabling CEPI's 100 Days Mission.
How quickly can Moderna update its mRNA vaccine for a new pandemic strain?
Moderna's mRNA platform can update its vaccine template in weeks once the target antigen sequence is known, compared to months for egg-based or protein-subunit conventional vaccines.
Why does the H5N1 Phase 3 trial matter for pandemic preparedness?
A successful trial establishes a regulatory-approved H5N1 mRNA manufacturing pathway. If a pandemic H5N1 strain emerges, Moderna can update the antigen and roll out a strain-matched vaccine FAR faster than starting from scratch.Source: CEPI
Did Moderna's cancer vaccine work in Phase 3?
Yes. Merck and Moderna said on 19 August 2026 that intismeran autogene with Keytruda cut recurrence in resected melanoma versus Keytruda alone in the 1,137-patient INTerpath-001 trial.Source: https://www.merck.com/news/merck-and-moderna-announce-phase-3-interpath-001-trial-of-intismeran-autogene-plus-keytruda-met-endpoints-of-recurrence-free-survival-rfs-and-distant-metastasis-free-survival-dmfs-in-patient/
What is Moderna's mRNA-1273 vaccine and when was it approved?
mRNA-1273 (Spikevax) is Moderna's COVID-19 vaccine, authorised in late 2020. It was the first large-scale demonstration that mRNA vaccines could be developed, manufactured and deployed at population scale.
Is Moderna making an H5N1 bird flu vaccine?
Yes. Moderna began the first Phase 3 trial of an mRNA H5N1 vaccine candidate in April 2026, backed by CEPI, making it the furthest-advanced H5N1 mRNA vaccine in clinical development.Source: CEPI
