UPDATE 1-Mexico to start late-stage clinical trial for China's mRNA COVID-19 vaccine

Updates with details on mRNA technology

- Mexico plans to start a late-stage clinical trial this month for a COVID-19 vaccine candidate developed by China using similar technology to shots from Moderna MRNA.O and Pfizer PFE.N, foreign minister Marcelo Ebrard said on Tuesday.

The phase III trial for the shot from China's Walvax Biotechnology 300142.SZ using messenger RNA (mRNA) technology will start on May 30 and involve 6,000 volunteers, Ebrard said in a Tweet.

Walvax is working with the Academy of Military Science (AMS) and Suzhou Abogen Biosciences to jointly develop the shot known as ARCoV or ARCoVax, China's first mRNA vaccine to enter Phase III trials.

The shot could be stored at 2-8 degrees Celsius for six months, a much less stringent temperature requirement than shots from western rivals, an AMS researcher leading the vaccine project said in April during a presentation at a vaccine event.

Mexico has already received doses of other vaccines from China's Sinovac Biotech SVA.O and CanSino Biologics 6185.HK688185.SS, and planned to order shots made by Sinopharm. nL1N2LB09J

China is currently using five domestically developed vaccines in its inoculation drive, although none use mRNA technology, which contains instructions for human cells to produce proteins that mimic part of the coronavirus.
