Provided are a pharmaceutical composition for resisting infection with SARS-COV-2 or a
mutant thereof, and a combined
drug thereof. To solve the problem of the lack of effective prevention and treatment drugs for infection with SARS-COV-2 or a
mutant virus thereof, provided are a recombinant
protein vaccine and / or an
adenovirus vaccine for preventing and / or treating an infection with SARS-COV-2 or a
mutant thereof, and in particular, provided are a
nasal spray administration compound formulation containing active ingredients of two vaccines, i.e., a recombinant
protein vaccine and an
adenovirus vaccine, and a combination of the two vaccines for
nasal spray administration, which can induce generation of strong
antibody and cellular immune responses
in vivo and block the binding of a
protein S of SARS-COV-2 to an ACE2
receptor of a host
cell, thus enabling a host to
resist coronavirus infection. Particularly, the present invention has good prevention and treatment effects on various mutant viruses.
