The statement of which is better, inactivated or adenovirus carrier vaccine for novel coronavirus, is inaccurate; there is no difference between good and bad vaccine results. The new coronavirus vaccine is designed to prevent infection with the new coronavirus. Currently, inactivated vaccines, recombinant protein subunit vaccines, and adenovirus-vectored vaccines are used, and all are capable of preventing infection. There are no large-scale studies comparing the effectiveness of different vaccines, so it is not clear which vaccine is more effective. The adenovirus vector vaccine, which requires only one injection, is a modified adenovirus that removes key genes and fills them with target genes of the new coronavirus. The new coronavirus genes are delivered to the body with the help of adenovirus vectors, which promotes the production of antigens in the cells and induces cellular immunity in the organism. The inactivated New Crown vaccine, which requires 2 doses, first inactivates the virus and does not cause infection when introduced into the body, but maintains the immunogenicity of the virus, which encourages the body to produce antibodies to protect against New Crown virus. Generally, antibodies are produced about 7 days after the first dose of vaccination, and on average, the antibody positivity rate reaches more than 90% about 28 days after the second dose of vaccination. After vaccination, it is necessary to stay under observation for about 30 minutes. It is recommended to avoid getting water on the vaccination site on the day of vaccination, avoiding strenuous exercise, avoiding spicy and stimulating diet, and following up with the doctor if you feel unwell.
