Animal vaccine researchers, belonging to biological research, are bound to be dangerous, but now all the work is dangerous, and the people's police, doctors and soldiers are all in danger, so they just need to strengthen protection and pay more attention. In animal vaccine research, such as virus research and inactivation, if the virus is pathogenic to humans and animals, it may be exposed if it is not handled properly. For example, brucellosis vaccine, brucellosis will lead to infertility, once people are infected, it is difficult to get better. However, the general education of this study is relatively high, and the protection of experimenters is relatively in place. It should be no problem to strengthen the awareness of self-protection.
