Comparison of X4 HIV-1NL4-3 in PBMC cultures from vaccinia naïve (N = 10) and vaccinia vaccinated (N = 9) subjects. Figure 2a shows cultures without and figure 2b shows cultures with pretreatment with autologous serum. No statistically significant difference between the vaccinated and unvaccinated subjects is found, however there is a trend toward reduced viral replication in the vaccinated subjects.
