Notes

• An HIV+ individual given acute ARV and undergoing STI developed a strong CTL immune response, but despite this was shown to be superinfected with second B clade virus. Some epitope variants of the second infecting virus were resistant to the initial CTL response.
• The second infecting strain had the variant fpWtwlhgl. The CTL response declined over time and the response to the second variant was lower than to the first one all the time points.
