Thanks for your feedback, Kia Wee Tan - unfortunately, because the government has it's hand on the throttle where vaccines are concerned, I don't see how you can get access to the "data" or the institution so that you can do a personal assessment of the efficacy or the quality of the development process for a vaccine. The most you can hope for is some future publication by a reputable news or government source -- most likely in a newspaper or TV announcement. Meanwhile, you could be on hold for quite some time waiting for said verification. It could be a long wait, and if you happen to work for some company that requires you to be vaccinated before they "put you on the floor", you might not have the option to wait.
