The Japanese Ministry of Health, Labour and Welfare granted the approval based on positive Phase III efficacy and safety data from the Oxford University-led clinical trial programme in the UK, Brazil and South Africa, and a Phase I/II trial in Japan.

Japan's Pharmaceuticals and Medical Devices Agency recommends that the use of Vaxzevria should be limited to adults and administered intramuscularly as two 0.5 mL doses given four to 12 weeks apart, with an interval greater than eight weeks being preferable to maximise its efficacy. This dosing regimen was shown in clinical trials to be well-tolerated and effective in preventing symptomatic COVID-19, with no severe cases and no hospitalisations more than 14 days after the second dose.[1]

Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, said: "We continue to expand global access to our vaccine and today's approval brings us one step closer to providing Vaxzevria to the people of Japan who urgently need protection from coronavirus. We are proud to have produced a vaccine for the world, which is playing a leading role in the global fight against the pandemic, with more than 400 million doses now supplied by AstraZeneca and sub-licensees to 165 countries."

Production of the vaccine in Japan is already underway, and the first doses are expected to be available in the coming weeks.

The vaccine has been granted a conditional marketing authorisation or emergency use in more than 80 countries across six continents and has also received Emergency Use Listing from the World Health Organization, which accelerates the pathway to access in up to 142 countries through the COVAX Facility.

Vaxzevria can be stored, transported and handled at normal refrigerated conditions (two-eight degrees Celsius/36-46 degrees Fahrenheit) for at least six months, and administered within existing healthcare settings.

AstraZeneca continues to engage with governments, international organisations and collaborators around the world to ensure broad and equitable access to the vaccine at no profit for the duration of the pandemic.

Vaxzevria

Vaxzevria (ChAdOx1-S [Recombinant]), formerly AZD1222, was co-invented by the University of Oxford and its spin-out company, Vaccitech. It uses a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees and contains the genetic material of the SARS-CoV-2 virus spike protein. After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus if it later infects the body.
