2. BMI between 18-30
3. Seronegative for Adenovirus 4 serum neutralising antibodies
4. Available for follow-up for the duration of the study
5. Willing and able to give written informed consent

6. At low risk of HIV infection and willing to remain so for the duration of the study defined as:

   • no history of injecting drug use in the previous ten years
   • no gonorrhoea or syphilis in the last six months
   • no high risk partner (e.g. injecting drug use, HIV positive partner) either currently or within the past six months
   • no unprotected anal or vaginal intercourse in the last six months, outside a relationship with a regular partner known to be HIV negative
7. Willing to undergo HIV testing
8. Willing to undergo a STI screen for chlamydia, gonorrhoea and syphilis
9. Must agree to require male sexual partner to use condoms, from at least 14 days before the first vaccination until at least 4 months after the last
10. If heterosexually active female capable of becoming pregnant, must (in addition to requiring male partner to use condoms) agree to use hormonal contraception, or to complete abstinence, from at least 30 days before the first vaccination until at least 4 months after the last. [Note: Acceptable hormonal contraception is combined (estrogen and progestogen containing) or progestogen-only hormonal contraception associated with inhibition of ovulation. Complete abstinence can be used, when in line with the preferred and usual lifestyle of the subject. Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, lactational amenorrhoea method, and IUD/IUS are not acceptable methods of contraception.]
