BEIJING (Reuters) - China's Suzhou Abogen Biosciences Co said its COVID-19 vaccine candidate using the messenger RNA (mRNA) technology and targeting the Omicron variant has obtained clinical trial approval in the United Arab Emirates.

With Friday's announcement, Abogen joins Pfizer/BioNTech and Moderna (NASDAQ:MRNA) in trialing candidates modified specifically against Omicron, a highly transmissible variant with increased resistance to antibodies elicited by existing shots.

Mainland China has vaccinated over 88% of its 1.4 billion people against COVID with non-mRNA shots. It has not approved any foreign vaccines, although real-world data indicated the two most used Chinese products, manufactured by Sinopharm and Sinovac, have lower effectiveness against COVID infection than mRNA shots from Pfizer/BioNTech and Moderna.

Besides the UAE, Abogen was communicating with regulators in China and other countries on potential clinical trials for the Omicron-specific candidate, it said in a statement.

An mRNA candidate based on an older coronavirus strain without major mutations, which Abogen co-developed with Walvax Biotechnology and a Chinese military-backed research institution, is being tested in a Phase III trial in China, Mexico and Indonesia.

Walvax is also partnering with Shanghai-based startup RNACure to develop a variants-targeting mRNA vaccine candidate, with design different from Abogen's.
