There are specific preventive measures for SARS virus prevention, that is, targeted preventive measures (it is possible to develop vaccines, but it takes a long time to solve the problem of virus reproduction) and non-specific preventive measures (that is, measures to prevent respiratory infectious diseases in spring, such as keeping warm, washing hands, ventilation, avoiding excessive fatigue and contact with patients, and going to crowded public places less).

Vaccine research

Clinical vaccine

1. Use mucosal vaccine and inhibitory antibody for immune prevention (based on the animal experimental model of monkeys).

2. Immunity to SARS vaccine can induce the production of inhibitory antibodies against coronavirus, indicating that mucosal immunity can trigger systemic immune response. In animal experiments, all the animals in the control group were infected by coronavirus, but none of the monkeys inoculated with SARS vaccine got sick.

3. The researchers treated ferrets infected by SARS virus with inhibitory human monoclonal antibody, which significantly reduced the replication of the virus in the lungs, prevented the lungs from developing into a typical pathological stage, and did not see the virus secreted and spread in the pharynx.

4. Studies show that respiratory mucosal immunity and immunization in animal models can effectively prevent SARS.
