It's different. Beijing Kexing and Dalian Kexing are not the same company, but the vaccines of the two companies are inactivated vaccines, which can be mixed. The vaccine stock solution of Dalian Kexing is produced by Beijing Kexing Zhongwei and packaged separately in Dalian Kexing. There is no difference between them.

The main difference between the two is that the manufacturers are different; Beijing biological vaccine manufacturer is China Sinopharm Group, and Kexing vaccine manufacturer is Beijing Kexing Zhongwei Biotechnology Co., Ltd.

Matters needing attention after vaccination with COVID-19 vaccine:

1. You need to stay in the hospital for observation for 30 minutes after COVID-19 vaccination, because if you feel unwell, you can be dealt with by the medical staff on the spot in time, and if you feel unwell, you can leave.

2. On the day of inoculation, keep the inoculation site dry and pay attention to personal hygiene. Within one week after vaccination, avoid contact with allergens and common allergens previously known to individuals, such as various seafood and other foods. Try not to drink, eat spicy food, and keep a good work and rest.

3. In addition to three and two doses of COVID-19 vaccine, there is also one dose of COVID-19 vaccine produced by Kangxinuo Company, but this vaccine is mainly used in special circumstances, so it has not been widely used at present.
