Summary

This study tests whether a short 'inoculation' message can help young women in South Africa resist misinformation about lenacapavir, a new twice-yearly injection for HIV prevention. 1,500 women aged 18-29 will be randomly assigned to receive either the inoculation message or unrelated health information, then exposed to false claims. Researchers will measure their intention to use lenacapavir and how believable they find the misinformation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this approach could help ensure that accurate information about lenacapavir reaches young women, supporting its uptake and HIV prevention efforts.
What could go wrong
This is a behavioral study, not a drug trial. It measures intentions, not actual HIV prevention. Results may not translate to real-world behavior or other populations.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
