Beijing Bio and Kexing Bio, if they are in Lanzhou University of Technology, both vaccines are vaccinated accordingly. Generally, the first vaccine belongs to the COVID-19 vaccine developed by Beijing Pharmaceutical Biology, because if you are in universities all over the country, basically everyone will be vaccinated with this vaccine.

It is always inoculated at the first injection. Then if it is the second or third injection, you may change to other vaccines, or you may still use Beijing biological vaccine. Then if it's a one-shot vaccine, it may be necessary to take the Kangxinuo vaccine.

However, the side effects of that kind of Kangxinuo vaccine may be relatively large, that is, uncomfortable symptoms may appear after injection, so these three vaccines are mainly used in Lanzhou University of Technology.
