Well apparently the chinky mRNA knock off works better than their other shit.
Of course that means nothing really.
It's like saying a litre of water with a drop of tequila in it will get you more pissed than a litre of water.
BEIJING, June 1 (Reuters) - A COVID-19 vaccine candidate from China's Walvax Biotechnology (300142.SZ) using mRNA technology triggered a stronger antibody response against the Omicron variant of the coronavirus as a booster dose than Sinovac's shot, clinical trial data showed.
The result for Walvax's ARCoV candidate, which is yet to be peer reviewed, comes as competition for the COVID booster market intensifies in China, where more than half of the 1.4 billion population have so far received a non-mRNA booster shot.
