Countries around the world have begun to use the new crown vaccine. Kong Fanyi, a clinical professor in the Department of Internal Medicine at the University of Hong Kong, believes that high-risk groups such as the elderly, obese and diabetic patients can be vaccinated first, but he also emphasizes that vaccination is not a panacea. Continue to wear masks and maintain personal hygiene. .
Kong Fanyi said on the Hong Kong and Taiwan program “Hong Kong Family Letters” that every new vaccine is released, and because there is no long-term data, everyone has doubts and it is completely understandable. Although there are reports about neurological problems such as facial paralysis and Gibb’s syndrome after vaccination, he pointed out that the chance of these conditions is very low, and there is no direct relationship between vaccines.
Kong Fanyi continued to point out that it may take two to three years or even longer to wait for data and documentation. Therefore, in an emergency, when governments and medical institutions use unregistered drugs, pharmaceutical companies can be exempted from liability under the terms of protection. It is a common practice, but vaccine manufacturers still have considerable responsibility to ensure the quality of vaccines.
He pointed out that from research and development to production, vaccines need to go through different procedures. First, they must go through animal experiments and then undergo three-stage human clinical tests. Extensive and accurate data must be available and approved by local authorities before they can be used. As for the vaccines that the Hong Kong government is about to purchase, two of the vaccines have already had Phase III clinical research reports. One has an effective rate of 95% and the other has a 70% efficiency.

He reminded that vaccination is not a panacea, and you must continue to wear masks and maintain personal hygiene. The effectiveness of each vaccine is affected by many factors such as age and medical history. In addition, we must also pay attention to how long the effectiveness of the vaccine can be maintained. If the vaccine only lasts for 12 months, it may need to be vaccinated every year. Therefore, we still need to continue to observe long-term reports to ensure effectiveness and sustainability. He also mentioned that he hopes to conduct the first phase of human testing for the nasal spray vaccine studied by the University of Hong Kong as soon as possible to contribute to the fight against the new coronavirus.
