Who are the key groups?

According to the national unified planning and deployment, novel Coronavirus vaccine vaccination adopts a “step by step” strategy.
As a first step, mainly for some key crowd immunization, focus groups, including engaged in imports of cold chain, port inspection and quarantine, ship pilotage, aviation flight, the fresh market, public transportation, medical treatment for disease control and the staff with high risk of infection, such as, as well as to the high-risk countries or regions to work or study.

With the conditional listing or official approval of the vaccine, the vaccination work of the general population will be rolled out in a comprehensive and orderly manner.
According to the briefing of the Joint prevention and Control mechanism of The State Council, After the outbreak of COVID-19, China has laid out five technical routes to promote vaccine research and development.
So far, according to the statistics of the World Health Organization, the vaccines that have entered clinical trials and those that have entered phase III clinical trials are among the first in the world.

Because the epidemic situation was brought under control earlier in China, China was not equipped to carry out phase III clinical trials. Therefore, all the five vaccines entered into phase III clinical trials in China were phase III clinical trials carried out abroad.

In what cases should COVID-19 vaccination be postponed?

In response to questions related to vaccination, the Shanghai CDC mentioned that at the present stage, it is recommended to postpone the vaccination of COVID-19 vaccine under the following circumstances:

Persons who are allergic to any component of the vaccine and have had a previous severe allergic reaction to the vaccine, such as acute allergic reaction, urticaria, eczema of the skin, dyspnea, angiogenic edema or abdominal pain;

Persons with fever, acute diseases, severe chronic diseases, or acute onset of chronic diseases;

Pregnant women and lactating women shall have a family planning within 3 months of inoculation;

A history or family history of convulsion, epilepsy, encephalopathy or mental illness;
Persons with uncontrolled epilepsy and other progressive neurological diseases, or with a history of Guillain-Barre syndrome;

Has been diagnosed with a congenital or acquired immune deficiency, HIV infection, lymphoma, leukemia or other autoimmune disease;

Known or suspected to be suffering from severe respiratory diseases, severe cardiovascular diseases, liver and kidney diseases, or malignant tumors;

Using immunomodulators such as anti-tumor drugs;

Have novel Coronavirus infection history;

Those considered unsuitable by clinicians or vaccination staff.

The specific instructions of the vaccine shall prevail.

Are vaccines safe?

National WeiJianWei medical health science and technology development and research center director Zheng Zhongwei said recently that in order to protect the people at high risk, in June, in accordance with the rules approved in accordance with the new vaccine emergency use, from July began a new vaccine inoculation work of emergency use, from July to now, on a voluntary, informed and agreed to under the premise of the high risk people exposed to have emergency vaccination, the cumulative has completed more than 100 doses of the new champions an emergency vaccination work, strict adverse drug reactions monitoring and tracking observation, no serious adverse reactions.

Should I continue to wear a mask after getting the COVID-19 vaccine?

The Shanghai Center for Disease Control and Prevention warned that vaccination can reduce the risk of infection to a certain extent, but the protection effect of any vaccine cannot reach 100 percent. A small number of people may still fail to produce protection or become ill after vaccination. When necessary, vaccinators should still cooperate with relevant departments for nucleic acid testing.
At present, the human immune barrier has not been established.
Therefore, personal protective measures such as wearing masks, washing hands frequently, opening Windows for ventilation, and maintaining a social distance should still be taken after vaccination.

Will the mutated virus render the vaccine ineffective?

Recently a novel mutation coronavirus emerged in The UK which has attracted worldwide attention.
Based on the information disclosed by who experts, health disease control experts and authoritative media, it is widely believed that the mutant strain has little impact on the vaccine and the public need not worry excessively.

Who health emergency project director Michael Ryan said in a press conference on December 21,, there is no any evidence of variation in the UK will be coronavirus will increase the severity of the disease, and no evidence of any mutation makes a higher virulence or erosion diagnosis method, the vaccine efficacy.

Most people respond to the vaccine by producing a series of antibodies that neutralise the virus by disrupting different parts of it, guardian analysis suggests.
So even though some of the antibodies produced by the vaccine may be rendered useless by mutations in the virus, others are unlikely to be affected.
Overall, the mutated virus is likely to have little impact on the vaccine.

On December 19, Wang Huaqing, chief expert and chief physician of immunization program of China CDC, said at the press conference of joint prevention and control mechanism of The State Council that the current research results showed that the novel Coronavirus mutation is within the normal range and has no effect on the vaccine effect.
