Abstract

SARS Vaccine Protective in Mice

Highlights

  • We have developed an inactivated virus vaccine that induces neutralizing antibodies and protects against SARS-CoV challenge

  • Immunogenicity of the vaccine was tested by immunizing BALB/c mice at 0, 2, and 4 weeks with 5 μg of inactivated virus combined with the adjuvant MF59, an oil squalene-in-water emulsion [6] approved for human use in Europe for an influenza vaccine

  • IgG subclass determination indicated a predominant Th2-type immune response similar to that observed in BALB/c mice vaccinated with a UVinactivated SARS-CoV plus alum [7]
