Note that SinoVax does NOT use any experimental unproven technologies. Its ingredients are published in the open literature (and don't contain anything "weird"), has been extensively tested on a range of the usual test animals, and been widely tested on humans. Seems the Chinese motto was "First, do no harm". It seems to be reasonably effective in preventing hospitalization, and VASTLY safer than the secret proprietary experimental formulations of so called "vaccines" being presently offered in Australia. It may be initially less effective against some strains of COVID-19, but it is very much safer.
