Which brand of domestic COVID-19 booster needle is better than COVID-19 vaccine? There are five brands

Which brand is good for domestic COVID-19 vaccine

Domestic COVID-19 vaccine brands are very good and have been approved for listing. However, according to the vaccination situation, most people only want to get the COVID-19 vaccine. In fact, it is unnecessary for everyone to deliberately play a COVID-19 vaccine brand, because what can enter the market and be played by everyone is controlled by the national quality, and vaccines that fail to pass the prevention standard will not be introduced into the market for everyone to play. All you need to pay attention to is that two doses of COVID-19 inactivated vaccine, one dose of adenovirus vector vaccine and three doses of recombinant protein vaccine (CHO cell) are required for recombinant novel coronavirus vaccine.

To sum up, there are five brands of COVID-19 vaccine in China, and their safety and effectiveness are controlled by specific data. Because there is no need to believe other people's rumors about which brand is good, no matter which brand it is, it is the same. You can rest assured to get vaccinated.

What are the brands of COVID-19 vaccine?

At present, China has five kinds of COVID-19 vaccines, namely, the inactivated vaccine of Sinopharm Beijing, the inactivated vaccine of Sinopharm Sinopharm Sinopharm Beijing, the inactivated vaccine of Sinopharm Sinopharm Wuhan, the recombinant COVID-19 vaccine of Zhifei Biology (CHO cell), and the adenovirus vector vaccine of Tianjin Kangxinuo, which have been approved for use. The specific brands are as follows:

Brand 1: the inactivated vaccine of Sinopharm Beijing

is actually a vaccine prepared by a series of purification technologies after inactivation of the cultured and amplified live virus through physical and chemical methods. The main feature is that the composition of the vaccine is similar to the natural virus structure, which is the closest. Usually, it has strong immunity and good safety. Long term storage at 2-8 degrees for two to three years, convenient transportation, and easy use in remote areas, using two doses of immunization.

Brand 2: Beijing Sinovac's inactivated vaccine

has released detailed results of the Phase 3 clinical trial of CoronaVac, a inactivated vaccine developed by Sinovac in collaboration with multiple partners, among healthcare workers in Brazil on the preprint website SSRN. The results of this experiment showed that the protective efficacy of two doses of CoronaVac against symptomatic COVID-19 reached 50.7%, and the protective efficacy against moderate to severe cases and severe COVID-19 reached 100%. It is worth mentioning that this study also provided a variety of detailed analysis data, including the protective effect after vaccination once, and the neutralizing effect of vaccinated volunteer serum on a variety of COVID-19 mutants.

Brand 3: The inactivated vaccine of Sinopharm Sinopharm Wuhan Biological Products

Duan Kai, director of Wuhan Institute of Biological Products, and Yuan Zhiming, president of Chinese Academy of Sciences Wuhan Branch, publicly demonstrated the COVID-19 inactivated vaccine jointly developed by the two units. It is understood that the COVID-19 inactivated vaccine produced by Sinopharm China Biological Wuhan Institute of Biological Products is conditionally listed.

Brand 4: Zhifei Biological Recombinant COVID-19 Vaccine (CHO Cell)

On March 10, the recombinant novel coronavirus vaccine (CHO Cell) jointly developed by the Institute of Microbiology of the Chinese Academy of Sciences and Zhifei Biological was approved for emergency use in China, becoming the fourth COVID-19 vaccine approved for emergency use in China, and the first COVID-19 recombinant subunit protein vaccine approved for clinical use in the world.

Brand 5: Tianjin Kangxinuo Adenovirus Vector Vaccine

China adopts adenovirus type 5 as the vector, introduces COVID-19 antigen gene, and makes live vector vaccine through bioreactor. The preparation process is relatively simple and the cost is relatively low. This vaccine not only induces good neutralizing antibody production, but also has a characteristic of enhancing cellular immunity, using a one shot immunization program. One shot immunization does have a very convenient feature for targeting some special emergency populations.
