Antibodies titers against GP120. The 965 (white square), 966 (no symbol), 969 (black circle), 975 (black square), 9611 (white circle), 9711 (white triangle) and 9712 (black triangle) Macaques are the Tat Oyi vaccinated Macaques. The 963 (white square), 964 (black square), 978 (white circle) and 9610 (black circle) Macaques are the controls vaccinated with β-gal. Six from the seven macaques vaccinated with Tat Oyi had a high level of GP120 antibodies (panel A) similar to the macaques controls (panel B). Antibodies against GP120 appears to not have play a role in the elimination of reservoir cells. This is well illustrated with macaque 966 (Panel A) that had no antibody against GP120 after the first challenge SHIV and a low level of antibodies after its second SHIV challenge.
