2. The specific vaccine situation can show the local vaccination information records and explain it to the relevant staff as much as possible.
Generally speaking, no matter where I live, I am willing to complete the vaccination process.
4. Sometimes when you are vaccinated in your permanent residence, you can't show the vaccination situation in your permanent residence on foreign health records when you are traveling or on business. At this time, just show your normal health green code and 14-day travel record.
At present, there are three kinds of COVID-19 vaccines in China, namely inactivated vaccine, adenovirus vector vaccine and recombinant subunit vaccine.
1. Inactivated vaccine: The three inactivated vaccine products approved for marketing in COVID-19 are produced by Sinopharm China Bio-Beijing Institute of Biological Products (Beijing Institute), Wuhan Institute of Biological Products (Wuhan Institute) and Beijing Kexing Zhongwei Biotechnology Co., Ltd. (Kexing Zhongwei). Its principle is to use African green monkey kidney (Vero) cells for virus culture and amplification, use β -propiolactone to inactivate the virus, retain antigen components to induce immune response, and add aluminum hydroxide adjuvant to improve immunogenicity.
2. Adenovirus vector vaccine: The adenovirus vector vaccine approved for conditional marketing is the recombinant COVID-19 vaccine (adenovirus type 5) produced by Kangxinuo Biological Co., Ltd. Its principle is to recombine novel coronavirus spike glycoprotein (S protein) gene into replication-deficient human adenovirus type 5 gene, and the recombinant adenovirus expresses COVID-19 S protein antigen in vivo to induce immune response.
3. Recombinant subunit vaccine: The recombinant subunit vaccine approved for emergency use is the recombinant COVID-19 vaccine (CHO cell) produced by Anhui Zhifeilong Kema Biopharmaceutical Co., Ltd. (Zhifeilong Kema). Its principle is to recombine novel coronavirus s protein receptor binding region (RBD) gene into China hamster ovary (CHO) cell gene, express it in vitro to form RBD dimer, and add aluminum hydroxide adjuvant to improve immunogenicity.
Under the flood of epidemic savings, for the sake of life safety, everyone needs to actively respond to anti-epidemic actions and take the initiative to vaccinate.
