At present, there are hundreds of research and development units of COVID-19 vaccine in the world, but few of them have been successfully marketed or approved for emergency use, mainly including inactivated vaccine, recombinant subunit vaccine, adenovirus vector vaccine and mRNA vaccine.

02. What vaccine is used in our province at present?

At present, COVID-19 vaccine used in our province is inactivated vaccine. The vaccine was prepared by chemical method, which made COVID-19 lose its infectivity and replication ability, while retaining its ability to cause human immune response. In the future, our province will adjust vaccine varieties in a timely manner according to the listing and supply of vaccines.

03. How long does it take for COVID-19 vaccine to produce protection and how long can it last?

At present, the protective efficacy of vaccines used in China has reached the relevant standards of Guiding Principles for Clinical Evaluation of Preventive Vaccines in novel coronavirus issued by the State Pharmaceutical Administration, and also meets the index requirements recommended by the World Health Organization's Characteristics of Target Vaccines in COVID-19.

At present, the immune persistence of inactivated vaccine in COVID-19 is still under continuous observation. The evidence shows that the protection period of the vaccine can reach at least half a year, but no vaccine can guarantee that the vaccinated population will produce 100% protection effect. Therefore, after vaccination, the protection standard cannot be lowered in daily work and life.

04. What is the safety of COVID-19 vaccine?

The vaccines used in our province are conditionally approved for marketing, and the safety and effectiveness of vaccines have been verified according to the process. From the monitoring situation, the incidence of adverse reactions of vaccination in COVID-19 is roughly the same as that of other inactivated vaccines, and most of the symptoms are mild. As long as you follow the guidance of medical staff, safety can be guaranteed and you can rest assured that you can vaccinate.

08. Can vaccines from different manufacturers replace vaccination in the second injection?

At present, there is no evidence that different manufacturers or different kinds of COVID-19 vaccines can replace vaccination. It is suggested that COVID-19 vaccine of the same variety from the same manufacturer should be used to complete the vaccination at this stage.

If there are any suspected adverse reactions, contact the inoculation unit in time. If the symptoms are slightly severe, it is recommended that the recipient seek medical advice in time.

12. Is the vaccine effective against virus variation or strains from other countries?

From the global monitoring of the variation of new crown pneumonia, it has not been found that the COVID-19 variant has a significant impact on the protection rate of COVID-19 vaccine which can be marketed conditionally in China. World Health Organization, national research institutions, vaccine manufacturers, etc. We are paying close attention to the mutation situation in COVID-19, and are also carrying out related research, which will provide early warning and scientific analysis basis for the follow-up vaccine development and application.

13. Will you get sick after COVID-19 vaccination?

Phase III clinical trials in many countries around the world have verified the effectiveness of the vaccine. However, it should be noted that up to now, the protective effect of any vaccine cannot reach 100%. A few people do not have protective power after vaccination, or are still at risk of getting sick, which is related to the characteristics of the vaccine itself and the personal physique of the vaccinator.

People with impaired immune function are at high risk of serious illness and death after infection in COVID-19. At present, there is no data about the safety and effectiveness of COVID-19 vaccine for people with immunodeficiency and HIV infection. The immune response and protective effect of this population may be reduced after vaccination. For inactivated vaccine and recombinant subunit vaccine, according to the safety characteristics of the same type of vaccine in the past, vaccination is recommended; For adenovirus vector vaccine, although the vector virus used is replication deficient, there is no safety data of the same type of vaccine in the past. It is recommended to vaccinate after fully knowing and weighing the risks and benefits.

18. Can patients with chronic diseases such as hypertension, hyperlipidemia, hyperglycemia and chronic gastritis be vaccinated with COVID-19 vaccine?

Patients with chronic diseases are at high risk of serious illness and death after being infected with COVID-19 virus. If the patient is in a stable state after treatment, the laboratory indexes such as blood pressure, blood sugar and blood lipid are stable, and chronic gastritis is in a non-attack period, you can be vaccinated.

19. Do I need to pay for COVID-19 vaccine?
