Pre-exposure prophylaxis of HIV-uninfected partner. We obtained our updated estimate for the per-act risk of HIV transmission from exposure to a contaminated blood product from a meta-analysis [ 5 ], which used a fixed-effects model with data limited to six studies where the blood donations were known to be contaminated with HIV [ 21 — 26 ].
