Gel with TFV-FTC combination or TFV alone fully protects macaques against vaginal SHIV_SF162P3 infection. The Kaplan-Meier curves show data on the number (#) of twice-weekly challenges with 10 TCID₅₀ of SHIV_SF162P3 and the number of uninfected macaques. (A) TFV-FTC gel. The differences in infection between the TFV-FTC gel arm and the placebo gel arm were statistically significant (P = 0.004; log rank test). (B) TFV gel. The differences in infection between the TFV group and the placebo gel group were statistically significant (P = 0.001; log rank test).
