The World Health Organisation (WHO) has granted an emergency use listing (EUL) to SK bioscience’s Covid-19 vaccine, SKYCovione.

SKYCovione is a self-assembled nanoparticle vaccine and the 12th Covid-19 vaccine to receive a EUL from the regulator.

Developed using pharmaceutical company GSK’s pandemic adjuvant, the vaccine targets the receptor-binding domain of the SARS-CoV-2 spike protein.

It was developed in collaboration with the Institute for Protein Design (IPD) at the University of Washington School of Medicine, with funding support from the Bill & Melinda Gates Foundation and the Coalition for Epidemic Preparedness Innovations (CEPI).

The vaccine is based on recombinant protein vaccine technology and is suitable for storage between 2°C and 8°C.

In a Phase III clinical trial, SKYCovione showed neutralising antibody responses against the SARS-CoV-2 parental strain.

The findings also showed that the Covid-19 vaccine had a standard safety and reactogenicity profile.

SK bioscience CEO Jaeyong Ahn stated: “Based on [its] immunogenicity and safety profile, SKYCovione has become the first Korean vaccine to be granted the WHO EUL.

“We will be committed to developing more vaccines, not just to strengthen Korea´s vaccine sovereignty but also to enable equitable access to the vaccine.”

Last month, the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) granted marketing authorisation for SKYCovione to prevent Covid-19 resulting from SARS-CoV-2 infection in people aged 18 years and above.
