Called into question? There was never any question. China refused to release any clinical study results on their vaccines and every independent test showed them to be 50% effective or less against the April 2020 variant. The South Africa, UK, India, and Brazil variants are no doubt crushing that garbage.
Some people have been asking for a whole-virus vaccine. Well, there you are: China has it ready for you. It doesn’t work, but at least it meets the narrow definition for what some people (who don’t seem to be aware of what “vaccine” means) consider to be a “real vaccine”.
Well said and revealing post.
