中国疫苗可能有比较长期的保护作用，中国疫苗保护率高吗
中国疫苗可能有比较长期的保护作用，中国疫苗保护率高吗
1. 中国三款新冠疫苗1.1 天津康希诺生产的腺病毒载体新冠疫苗
China has produced three COVID-19 vaccines, each with its own features. For example, the adenovirus vector COVID-19 vaccine produced by Tianjin CanSino has a high protection rate of 90.98% against severe cases.
2. 疫苗生产技术路线2.1 国内疫苗和国外疫苗采用不同的技术路线
Different from the Chinese vaccines, the Pfizer/BioNTech vaccine, which is already on the market in the United States, has an efficacy rate of 95%. The Sinopharm vaccines have not provided official protection rate data, but their efficacy is expected to be high.
3. 国内不同疫苗的情况3.1 科兴新冠灭活疫苗
The protection rate of the Sinovac vaccine is 91.25%, ranking first in China. It is a Vero cell inactivated vaccine known as CoronaVac. In Brazil, after receiving two doses of the vaccine, the protection rate was 50.65%.
3.2 国药中生北京公司的新冠灭活疫苗
The COVID-19 inactivated vaccine produced by Sinopharm's Beijing Institute ranks third in China. It has a total efficacy of 72.51%, with 100% protection against confirmed moderate to severe cases.
4. 中国疫苗的长期保护作用4.1 中国疫苗保护作用的可能性
The data shows that those who received Chinese vaccines developed effective antibodies against the virus, achieving a protection rate of 94%. This suggests that the Chinese vaccines may have a long-term protective effect.
4.2 新冠疫苗在未来的应用
If the impact of COVID-19 on human health gradually decreases, the possibility of long-term coexistence between COVID-19 and humans may become a reality. In the future, people may need to receive COVID-19 vaccines annually if the protection rate lasts longer than a year.
Overall, China's COVID-19 vaccines have shown good protection rates and safety records. The side effects after vaccination with Chinese vaccines have been minimal. With the effectiveness of Chinese vaccines proven through scientific data, criticisms from Western countries regarding the Chinese vaccines are unfounded. As the world moves toward increased vaccination coverage, it is essential to continue monitoring and evaluating the performance of vaccines against emerging variants of the virus.
