The government announced today that it has reached a procurement agreement with Kexing Biotechnology in the Mainland and the introduction of BioNTech from Germany and Pfizer Pharmaceuticals by Fosun Pharma. The first batch of 1 million doses of COVID-19 vaccine from Kexing Bio will arrive in Hong Kong as soon as January next year.

However, Chief Executive Carrie Lam Cheng Yuet-ngor clearly stated that it is difficult for the public to choose vaccines. She pointed out that this time it is not for market behavior to choose. Given the limited supply, the need to deal with priority vaccinations, and the different delivery times of vaccines to Hong Kong, "You cannot say that you have free choice of vaccines. I believe Not in the end."

Senior Counsel Tang Jiahua, a member of the Executive Council, linked the news of the arrival of vaccines to Hong Kong on social media in the afternoon, and said that "I finally wait until this day, I believe Hong Kong people are free to choose which vaccine." This is different from what Lin Zheng said.

When receiving enquiries, Tang Jiahua responded that he believed that Lam Cheng’s statement was mainly due to the different batches of vaccines arriving in Hong Kong. He believed that there was only one vaccine in stock and there was no choice at all. It is expected that the public would not refuse to receive vaccines from a certain pharmaceutical factory because of the initial rejection. The vaccination is not allowed in the future.

The government announced that it has signed an agreement with a pharmaceutical factory to purchase the new crown pneumonia vaccine, and those arriving in Hong Kong from December 22 must stay in designated hotels.

Looking through the information, the effectiveness of vaccines from different pharmaceutical companies is different. For example, Kexing Biotech has not provided the final effective rate, and the effectiveness of other pharmaceutical companies is also different. It is a concern that different vaccines are administered. The actual effect will be Is there a difference.

However, Tang Jiahua said that according to his understanding, a general vaccine with an effective rate of 50% is sufficient.

Looking through the documents, the U.S. Food and Drug Administration (FDA) required that the initial effective rate be at least 50% in the "placebo test" for the development of the new crown vaccine.

Kexing Biotechnology uses traditional methods to make vaccines (inactivated vaccines, made from killed pathogens). In addition, pharmaceutical companies use the principle of mRNA (messenger ribonucleic acid) to extract part of the ribonucleic acid encoding protein (ie mRNA) from the virus. Into a vaccine, but there has never been an example of large-scale mRNA vaccination in history.

Tang Jiahua said that it is said that traditional vaccines are safer, and many of his doctor friends advised him not to vaccinate vaccines made by new methods.

As for whether the public can choose?

Tang Jiahua believes that the government will not deliberately conceal the source of the vaccine. After the supply of various vaccines stabilizes later next year, the public will still have the opportunity to choose. He does not believe that the public will not be vaccinated in January because the first batch of vaccines will be manufactured by individual pharmaceutical companies. Therefore, no vaccination will be arranged in the future.

However, he also admitted that he did not understand the arrangements of the vaccine from the Chief Executive, and said with a smile, "I hope my calculation is correct."
