COVID-19 vaccine has been vaccinated in our city, only one shot is needed.

This vaccine is the only COVID-19 vaccine with adenovirus vector technology in China. Immune protection can be achieved quickly by single dose inoculation, which provides a strong guarantee for realizing group immunity in a shorter time. The mid-term data of Phase III clinical trials showed that the overall protective effect of the vaccine on all symptoms was 68.83% and the protective effect on severe cases was 95.47% after a single injection/0/4 days.

Compared with the three COVID-19 vaccines used in our city before, adenovirus vector vaccines are completely different in technical principles and vaccination procedures, ranging from 65438 08 years old, but the vaccination methods and safety are the same.

First of all, the technical principles are different. The adenovirus vector of this vaccine removes the genes related to replication in adenovirus, so that the virus will not replicate in human body. Then the gene of the new coronavirus spike protein is inserted into it. This newly inserted gene allows the recombinant virus to replicate COVID-19 spike protein in human body. When our immune system finds spike protein, it will start the immune response and remember its appearance. The next time it meets the real COVID-19, it will react immediately and remove them.

Secondly, the basic immunity of adenovirus vector vaccine is 1 dose according to different vaccination procedures; At present, the basic immunization program of inactivated vaccine in COVID-19 is suggested to be 2 doses, and the inoculation interval is suggested to be 3-8 weeks; 3 doses of recombinant COVID-19 vaccine; It is suggested that the interval between two adjacent doses should be ≥4 weeks, the second dose should be completed within 8 weeks after 1 dose, and the third dose should be completed within 6 months after 1 dose.
