COVID-19 Vaccine safety and effectiveness
Zheng Zhongwei, leader of the Vaccine R&D Special Team of the Joint Prevention and Control Mechanism Research Team of the State Council, and Director of the National Health and Health Commission's Medical and Health Technology Development Research Center, said: "According to the Phase I, Phase II, and Phase III clinical trials of my country's new crown vaccine, and Judging from the emergency vaccination of nearly one million doses of vaccines that my country has carried out, my country's new crown vaccine is very safe."
In the vaccination test, although there were some minor adverse reactions, there were no serious adverse reactions.
Wang Huaqing, chief expert of the China Centers for Disease Control and Prevention's immunization program, said that the main time for the new crown vaccine to take effect is two weeks after the second dose of the vaccine, and it will produce a better immune effect.
At the same time, the protective efficacy of a vaccine has a great relationship with the vaccination rate. When the vaccination rate in the population reaches a very high level, the immune barrier is established.
Who needs emergency vaccination?
According to Zheng Zhongwei, director of the Science and Technology Development Center of the National Health Commission, according to relevant regulations, emergency use (trial) is limited to specific groups of people who have high exposure risks and cannot use the current effective protective measures to protect them; People who use vaccines urgently should not be taken lightly, and other protective measures and methods should not be reduced.
According to the unified deployment of the State Council, the key personnel for new crown vaccination will include cold chain logistics personnel, customs border inspection personnel, medical disease control personnel, as well as farmers' markets, seafood markets, and public transportation personnel.
Experts pointed out that after vaccination, you should pay attention to any abnormalities in your body. After being vaccinated with the new crown vaccine, the recipient should stay at the vaccination site for 30 minutes to prevent acute allergic reactions. After the observation is normal, they can leave. After leaving, if the recipient has a high fever exceeding 38.5 degrees Celsius, or a local redness or swelling of more than 2.5 cm in size, he should report to the vaccination doctor in time and go to the hospital as soon as possible.
These people are not recommended to receive the new crown vaccine:
