COVAX-19 (or SpikoGen) is a recombinant protein-based COVID-19 vaccine developed by South Australian-based biotech company Vaxine, in collaboration with CinnaGen, a private company with operations in the Middle East. It is under clinical trial in collaboration with the Iranian company CinnaGen.[3][4][5]

Pharmacology

edit

COVAX-19 is a recombinant protein subunit.[6]

History

edit

Vaxine began work on a COVID-19 vaccine in January 2020. After developing a vaccine adjuvant the company decided to focus on a "recombinant protein-based vaccine". A phase 1 human trial started in June 2020. The phase 1 trial involved 40 participants, 30 of whom received the vaccine. The remaining ten participants received a saline placebo.[7]

Phases 2 and 3 clinical trials of COVAX-19 are being conducted in Iran under a co-operation agreement.[8] Phase 2 clinical trials started in May 2021 and Phase 3 trials commenced in August 2021. In the phase 2 trials, 400 Iranian volunteers were injected with either a placebo or the first dose of the vaccine. If the studies are successful, Cinnagen will produce the vaccine under the name SpikoGen in Iran.[7][9]
