Does suppressive therapy stop transmission?

Suppressive antiviral therapy among persons with HIV and HSV infection does not reduce the risk for either HIV transmission or HSV-2 transmission to susceptible sex partners (88,505).

How much does valtrex reduce risk of transmission?

Corey et al. (17) found a 48% reduction in the risk of transmission, but this reduction was from an acquisition risk of 3.6% to 1.9%. Thus, transmission is a rare event without valacyclovir use. Furthermore, when transmission does occur, most people do not develop symptomatic genital herpes.
