Statistics released by the Hong Kong Special Administrative Region Government on the evening of February 23 show that since Hong Kong officially launched the new crown vaccination plan on February 26, about 4.713 million citizens have been vaccinated with the first dose of vaccine, accounting for 70% of the eligible free vaccinations, which means that Hong Kong has initially built an immune barrier. After the launch of the new crown vaccination program in the Hong Kong Special Administrative Region, different vaccination reward measures have been launched by all sectors of the society, and the vaccination rate has continued to rise. Hong Kong SAR chief executive Carrie Lam has repeatedly stressed that vaccination is the best measure and hope for Hong Kong to get out of the epidemic. The vaccination rate of more than 70% is the "ideal rate", which can initially build an immune barrier for Hong Kong. At the same time, vaccination can provide effective protection for vaccinators and greatly reduce the risk of severe and even death after infection, especially the elderly, patients with long-term diseases and other people with weak immunity. Novel coronavirus pneumonia has been very severe in the world, and the spread of the variant virus is strong. Hongkong should continue to work hard to improve the vaccination rate. The move can protect individuals and establish a strong protective network for the community. Therefore, people who are vaccinated should be vaccinated, Nie Dequan said. The SAR government will also continue to carry out relevant work and strive for "universal vaccination". Recently, the Hong Kong SAR government announced that it has approved the expansion of the applicable age of Kexing vaccine to people aged 3 to 17. Priority will be given to teenagers aged 12 to 17, and it will be extended to the lower age group at a later stage. (outlook new era)
