Does it matter that the first dose of COVID-19 vaccine is inoculated with Chengdu biotechnology and the second dose is inoculated with Beijing Kexing Zhongwei?
COVID-19 vaccine 1 was inoculated with Chengbi No.2. Does it matter if Beijing Kexing Zhongwei? Of course it matters. 1 injection is biotechnology, and the second injection is definitely biotechnology. You can't get two different COVID-19 vaccines. Even if you go to the hospital for an injection, he won't give you two different injections, so you should give the doctor what you need for the second injection at 1 injection point. This is all science. Believe in science.
