Yeah I misunderstood the news, probably should have looked at any actual accompanying scientific report(s) rather than a news report by itself. Devil is in the details as it's turning out....
Too late to edit so I just left the earlier post behind.

To his defense, this doctor has said publicly he believes in China's numbers and results and sees no reason why not to believe them when the rest of the Western MSM are casting doubt on China's numbers and recovery.

He has to, as it's the case with all the other western naysayers when they see the people in Wuhan were already coming out to party in some big public swimming pools.
You should watch the rest of his videos. You should be able to gather where his stand is, either by direct or indirect inference, on the ability of the Chinese authorities, scientists/doctors in their handling of the virus pandemic.
In one video, he blames the Chinese doctors for claiming that chloroquine could be effective in curing COVID-19.
In another video, he agreed with Trump that COVID-19 could have been leaked from a lab in Wuhan and said that Trump has no reason to lie. And that was during the time when Trump was making the claim that disinfectants should be injected into the body to kill the virus.
He is quiet interesting to listen to, but ruins it with his silly prejudices.
It didn't stop Mike Pence trying to take credit on behalf of the orange one though.
The n is still relatively small and like I said it’s only 7 days after the 2nd vaccine dose. Also it needs to be store in -80 or will perish 5 days in fridge.
that said this vaccine has shown the best results yet.
don’l let the market trick you thinking it’s a magic bullet though! The vaccine likely won’t give available thus flu season.

In order to get formal approval from FDA, they will have to publish their data. That will require peer review.
For effectiveness of vaccines, it is tolerable to have a small scale trial, especially in an urgent time like now. You will need a very large n (typically thousands to tens of thousands) for safety evaluations. Keep in mind that, to test effectiveness, you are looking for positive data. For side effects, you are looking for negative data. To find those minor but potentially serious side effects, you will need a large data set.
Also, a large data set is not always a good thing. I’m sure they have done a proper power analysis to justify their sample size (for testing effectiveness). It’s not always good to have large data set. Too many data points will give you false significance between placebo and test groups even if the differences are small and meaningless.
To be honest, I’m quite surprised by the amazing effectiveness. I’ll have to look at the actual data to see what’s going on. The key is their demographics table, typically their Table 1... How have they picked their samples...

Is Fosun just a company supposed to be producing and distributing the Pfizer and BioNTech vaccines? It is not part of developing work besides organizing clinical trails. So I don't think such role deserve being mentioned. Think about the Chinese vaccines being trailed in other countries, the host countries institutes are not really mentioned much either if at all.

For effectiveness, you are testing significant differences between two data sets, placebo and test groups. For this type of comparison, you will need a sample size that should be carefully determined. A sample size too large will give you statistical significance even when the differences between two groups are very small. That's why you need a power analysis to determine the most proper data size. Power analysis will be one of the first things peer review will look at.
For safety, you are looking for a percentage of serious side effects within a single data set (including all those who get injections). No comparison involved. Then the larger the set the better. The harder you look, the more likely you will find those minor but serious side effects, and more confident you can be of the vaccines.
