Moderna has completed the real-time review process for its application to the US Food and Drug Administration (FDA) seeking full approval for its COVID-19 vaccine in people aged 18 years and above, the company said on Wednesday (Aug 25).
The news comes within days of US regulators granting full approval to Pfizer-BioNTech's COVID-19 vaccine, developed with the same mRNA technology as Moderna's.
Messenger RNA (mRNA) vaccines prompt the human body to make a protein that is part of the pathogen, triggering an immune response.
US health officials expect full approval for COVID-19 vaccines will help win over vaccine skeptics and prompt more state and local governments, as well as private employers, to impose vaccine mandates.
Moderna's completed submission includes data from a late-stage study that showed 93 per cent vaccine efficacy, even through six months after administration of the second dose, the company said in a statement.
As part of the submission, Moderna has requested a priority review designation for its vaccine, currently available in the United States for people aged 18 and older under an emergency use authorisation (EUA) granted by the FDA in December.
So far, the company has released more than 300 million doses of the vaccine to the US government.
