The U.S. Food and Drug Administration has stated that any potential coronavirus vaccine will need to be at least 50 percent effective to be approved. This means that the vaccine will need to prevent infections in at least 50 percent of the people who receive it.
The study participants are anonymously divided into two categories: a “control” group that receives either a placebo or a vaccine not related to the coronavirus that already exists, and a group that receives the experimental coronavirus vaccine. “If you have 10 people who got sick in the control group versus two people who got sick with the vaccine, you could say that the vaccine is doing better, but the numbers are too small,” she said. “If you have 150 cases, it may take 30,000 people to get there, but you would have enough to reliably detect a difference between the two groups.”
“You can’t detect much in small numbers, but when you move into larger trials, you could identify some of the less common side effects,” said Dr. Jeff Kwong, interim director of the Centre for Vaccine Preventable Diseases at the University of Toronto’s Dalla Lana School of Public Health in Toronto, Canada.

Then why CCP insists all the hongkongers have to take its vaccine? Can all the free countries rescue all the hongkongers? Hong Kong is under the humanitarian crisis!
Will never be the case, the entire Big Pharma industry is compromised... no trust till disclosure & Trials.
Rushing a vaccine could prove to be just as fatal as the virus itself. People could be lured into a false sense of security thinking they are immune only to get it and die. We need to tread lightly.
Hard pill to swallow especially after the vaccine for the swine flu
