RESUMO
An HIV-vaccine consisting of a DNA prime, recombinant fowlpox virus (rFPV) boost was evaluated in a double-blind placebo controlled trial. One milligram of pHIS-HIV-B expressing mutated gag, pol, env, vpu, tat and rev was administered at weeks 0 and 4 boosted by 5 x 10(7) pfu rFPV-HIV-B expressing gag/pol at week 8. The vaccine regimen was safe, but there was no difference between vaccine (n = 18) and placebo recipients (n = 6) for Gag or Pol-specific T-cell immune responses at week 9.

PURPOSE: To examine differences between Australian-born and Asian-born first-year university students in Sydney in their sexual behavior and knowledge about the prevention and transmission of human immunodeficiency virus (HIV) and other sexually transmissible infections (STIs). METHODS: Students were recruited from a stall during the student Orientation Week in both 2002 and 2003 at the University of New South Wales. A short questionnaire was completed and returned anonymously. Data on age, gender, country of birth, sexual behavior, and sexual health knowledge were collected. A score was calculated based on the sum of the correct answers given to 12 HIV/STI transmission and prevention questions. The students were then divided into three groups according to their country of birth (Australia, Asia, and elsewhere) and their knowledge scores were compared. Students born in certain Asian countries were also asked their perception of the HIV epidemic in their home country compared with Australia. RESULTS: A total of 1185 first-year students completed the questionnaire. Although older on average, Asian-born students were less likely to have had sexual intercourse and had had fewer sexual partners. They also had consistently poorer HIV/STI knowledge scores than Australian-born students. Students born in China, Hong Kong, Indonesia, Malaysia, and Singapore but not Thailand underestimated the prevalence of HIV in their country of birth in comparison with Australia. CONCLUSION: The combination of poorer knowledge, apparent misconception of the extent of HIV epidemic in their home country (or Australia), and potential later frequent travel indicates a potential risk for later transmission of HIV/STIs. The university is an underused setting for prevention health education.
