Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Are negative for (HIV) infection at screening
  • Is healthy on the basis of physical examination, medical history, (ECG), and vital signs measurement performed at screening
  • Are willing/able to adhere to the prohibitions and restrictions specified in the protocol and study procedures
  • Female participants of must have a negative serum pregnancy test (beta human chorionic gonadotropin [beta hCG]) at the Screening visit, and a negative urine pregnancy test pre-dose on Day 1
  • Are assessed by the clinic staff as being at low risk for HIV infection

Exclusion criteria

Exclusion Criteria:

  • Has chronic (measured by hepatitis B surface antigen test) or active (measured by hepatitis C virus [HCV] Ab test; if positive, HCV ribonucleic acid [RNA] PCR test will be used to confirm active versus past HCV infection), active syphilis infection, chlamydia, gonorrhea, or trichomonas . Active syphilis documented by serology unless positive serology is due to past treated infection
  • Has had a thyroidectomy or active thyroid disease requiring medication during the last 12 months (not excluded: a stable thyroid supplementation)
  • Has had major psychiatric illness and/or substance abuse problems during the past 12 months (including hospitalization or periods of work disability) that in the opinion of the investigator would preclude participation
  • Has been in receipt of any licensed vaccine within 14 days prior to the first dose of study vaccine/placebo, plans to receive within 14 days after the first study vaccination, or plans to receive within 14 days before or after the second, third or fourth vaccination
  • Is a recipient of a prophylactic or therapeutic vaccine candidate at any time, or a recipient of other experimental vaccine(s) within the last 12 months prior to the Day 1 visit (Vaccination 1). For participants who received an experimental vaccine (except HIV vaccine) more than 12 months prior to the Day 1 visit (Vaccination 1), documentation of the identity of the experimental vaccine must be provided to the sponsor, who will determine eligibility on a case-by-case basis
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

An AE was defined as any untoward medical event that occurred in a participant administered an investigational product, and it did not necessarily indicated only events with clear causal relationship with the relevant investigational product. Unsolicited AEs were defined as the AEs other than those categorized as "solicited AEs" and were required to be collected for any events that occurred from the time of vaccination and through the subsequent 28 days.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 25, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
