Extended Data Fig. 2: Virulence of VACV mutant lacking F14 in the intranasal mouse model of infection.
BALB/c mice were infected intranasally with 5×103 p.f.u. of the indicated VACV strains and their body mass was measured daily. Body mass is expressed as the percentage ± s.e.m. of the mean of the same group of mice on day 0 (n = 5 mice).
