COVID-19 has caused millions of deaths globally and has been declared a pandemic by the World Health Organization (WHO). To help fight the pandemic, Valneva has developed VLA2001, currently the only whole virus, inactivated, adjuvanted vaccine candidate in clinical trials against COVID-19 in Europe.

  • Adjuvanted with Alum and CpG 1018
  • Highly-purified

Valneva Signs Purchase Agreement with European Commission for up to 60 Million Doses of VLA2001

Valneva signed an Advance Purchase Agreement with the European Commission to supply up to 60 million doses of its inactivated COVID-19 vaccine candidate, VLA2001, over two years (Press release).

Press Release

Rolling submission with the MHRA in the UK commenced

In August 2021, Valneva commenced rolling submission, for initial approval of VLA2001 with the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (UK).

VLA2001 elderly, adolescent and booster trials

As part of the product development strategy, Valneva has initiated additional clinical trials to support future approval in further age groups, in addition to adults.

Valneva has completed recruitment of 306 volunteers aged 56 years and older in New Zealand (Press release) into its VLA2001-304 trial and expects topline data in early 2022. Valneva has also announced the start of recruitment of adolescents as an expansion of the Cov-Compare trial (Press release).

The Company is preparing for trials in children (5-12 years of age) and a Valneva sponsored booster trial to evaluate VLA2001’s booster performance for people in need of a booster.

Designed and manufactured in Europe

VLA2001 was developed by Valneva’s R&D teams in France & Austria. It is the only inactivated, adjuvanted whole virus COVID-19 vaccine candidate in clinical trials in Europe.

Valneva’s UK-based manufacturing facilities

Valneva’s facility in Livingston, Scotland has been producing FDA/EMA/MHRA approved commercial-grade travel vaccines for more than a decade.


Valneva’s fill and finish capacities in Sweden

Initially dedicated to the production of the Company’s cholera vaccine, Valneva’s facility in Solna has been expanding its capacity in order to provide full fill and finish operations for the VLA2001 vaccine.



FAQ about VLA2001

What is VLA2001 and how is it different from other approaches?
  • VLA2001 is a Vero-cell based, highly-purified inactivated whole virus vaccine candidate.
  • VLA2001 is currently the only whole virus, inactivated, adjuvanted vaccine candidate in clinical trials against COVID-19 in Europe.
  • The inactivated vaccine is a traditional and proven approach that has been used for decades. [1]
  • An inactivated SARS-CoV-2 vaccine is expected to be suitable for wide deployment.
  • Valneva’s vaccine candidate is based on the same manufacturing platform the Company already uses to produce its FDA/EMA/MHRA approved JE vaccine.
  • VLA2001 combined with alum and Dynavax’s adjuvant CpG 1018 has induced a strong immune response and generated high titers of neutralizing antibodies in a Phase 1/2 trial (Press release).
  • Valneva’s inactivated SARS-CoV-2 vaccine is expected to have a two-dose regimen.
  • VLA2001 is expected to conform with standard cold chain requirements (2 degrees to 8 degrees centigrade).

Will VLA2001 be safe and effective against SARS-CoV-2?

Valneva is working as quickly as possible to develop a safe and effective vaccine against COVID-19, VLA2001 is being tested in clinical trials to confirm safety and effectiveness against this disease. Valneva reported positive Phase 1/2 data in April 2021 (Press release).

Topline results of Valneva’s Phase 3 trial released in October 2021 showed that VLA2001 induced high levels of neutralization antibody titers as well as broad T-cell responses, and was well tolerated (Press release).

In addition, Valneva has a very solid database on the safety of this inactivated virus approach from its JE vaccine, which has been FDA/EMA/MHRA approved for over a decade.

When could Valneva deliver an approved COVID-19 vaccine?

Valneva commenced rolling submission for initial approval with the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) and is preparing to commence rolling submission for conditional approval with the European Medicines Agency. Valneva believes that initial approval for VLA2001 in the UK could be granted later this year.
