Vector replication and expression of HIV-1 antigens by the HIV/AIDS vaccine candidate MVA-B is not affected by HIV-1 protease inhibitors

► Effect of HIV-1 protease inhibitors on the HIV vaccine candidate MVA-B. ► HIV-1 protease inhibitors do not affect MVA-B virus growth kinetics in cultured cells. ► HIV-1 protease inhibitors do not affect MVA-B expression of HIV-1 antigens. ► These results highlight the potential of MVA-B for use in HAART-treated AIDS patients.
