Abstract: Disclosed is a mutant of a wild-type RSV F protein. The binding experiment of a pre-fusion conformation trimer-specific monoclonal antibody AM14 shows that the mutant provided in embodiments can have strong activity of binding to the AM14 monoclonal antibody, while the wild-type RSV F protein before artificial mutation has no activity of binding to the AM14 monoclonal antibody. The accelerated stability test result shows that the activity of binding of the mutant provided in the embodiments when placed in a 37° C. environment for four weeks to the AM14 monoclonal antibody does not change obviously. The animal immune experiment result shows that compared with the wild-type RSV F protein before artificial mutation, the mutant provided in the embodiments can induce production of a neutralizing antibody having a higher titer.
