1. Can different brands of vaccines be inoculated in superposition?
He Qinghua, the first-level inspector of National Health Commission CDC, said that more research is needed on whether vaccines produced by different enterprises can be superimposed or replaced by vaccination. And will put forward clear policy measures according to the research results after the research results come out.
He said that at present, the four vaccines conditionally listed in China have been examined and approved by the competent government departments, which are safe and effective. The public can be vaccinated as soon as possible in accordance with the unified arrangements of the provinces, autonomous regions and municipalities where they are located.
2. Can people over 61 be vaccinated?
"After full evaluation, some areas have begun to vaccinate the elderly over 61 with good physical conditions." He Qinghua replied that at present, vaccine research and development units are also accelerating research and development. After clinical trials have obtained sufficient safety and effectiveness data, vaccination will be carried out on a large scale for the elderly over 61 years old.
3. which groups are not suitable for vaccination?
He Qinghua introduced that the instructions of the four vaccines that have been conditionally marketed at present clearly define the vaccination contraindications, and it is not recommended to vaccinate people who are allergic to the ingredients contained in the vaccine, angioneurotic edema, dyspnea, epilepsy or other nervous system diseases, and have a history of Guillain-Barre syndrome.
He suggested that pregnant and lactating women should not be vaccinated with COVID-19 vaccine.
Wang Huaqing, chief expert of immunization program of China CDC, said that if pregnancy is found after vaccination, it is not recommended to take special medical measures, such as termination of pregnancy, based on the characteristics of vaccines in COVID-19 and previous experience in using vaccines. He suggested that this group of people should do a good job in pregnancy follow-up and regular examination.
4. Can I take off my mask after vaccination?
Feng Zijian, deputy director of China CDC, said that because the global COVID-19 epidemic is still prevalent, the domestic vaccination rate is low, and people or articles from high-prevalence areas still have the risk of spreading in China.

5. What are the adverse reactions after vaccination?
"Adverse reactions currently monitored mainly include local and systemic reactions." Wang Huaqing introduced that local adverse reactions include pain, redness and induration, which will heal by themselves without treatment, while systemic adverse reactions include headache, fatigue and low fever.
He introduced that the reports of adverse reactions currently received are suspected adverse reactions, that is, reactions suspected to be related to vaccines. In the follow-up, more serious adverse reactions will continue to be investigated, and the diagnosis will be made by the expert group through supplementary investigation and understanding of vaccination history and disease situation.
"No matter from the results of clinical trial research, emergency use research and post-marketing monitoring, the adverse reactions of vaccines in COVID-19 are similar to those of similar vaccines used in the past, and there is no abnormality." Wang Huaqing said.
6. Will you get infected after vaccination?
"Generally speaking, the role of vaccine is to make most people have protective power and establish immune barrier, and its effect of preventing severe diseases is more obvious." Wang Huaqing said, judging from the evaluation results of the vaccines currently used abroad, a small number of people did fail to protect after vaccination. He said that individual cases of failure will be studied and investigated.
7. What is the guarantee of vaccine production?
Mao junfeng, deputy director of the consumer goods industry department of the Ministry of industry and information technology, said that at present, five vaccines have been approved for conditional marketing or emergency use, including three inactivated vaccines, zero adenovirus vector vaccines and zero recombinant protein vaccines.

He said that after 31 consecutive days, there were no new confirmed cases in Shaanxi Province, and on March 8th, there were 1 new confirmed cases in Shaanxi Province.

For new sporadic cases, we should find them together and put them out together to ensure that there is no large-scale rebound.
