Understanding your International AIDS Vaccine Initiative data breach notification letter
If a International AIDS Vaccine Initiative letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
The International AIDS Vaccine Initiative (IAVI) is a global non-profit scientific research organization dedicated to the development of vaccines and biomedical innovations for HIV and other infectious diseases. Given its role in clinical research and public health, the organization typically collects and stores sensitive personal information, including names, dates of birth, and detailed health-related data from clinical trial participants and research partners. In 2025, IAVI officially reported a data security incident to the New Hampshire Attorney General. If you have received a formal data breach notification letter, it indicates that your personal information may have been involved in this incident. This notice is intended to inform you of the event and provide guidance on the steps you can take to protect your identity and personal security.
What to do after the letter
Confirm the notice is genuine
A legitimate International AIDS Vaccine Initiative notice references the specific incident reported to the New Hampshire Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
Find out whether you have a claim
Whether the International AIDS Vaccine Initiative breach gives you a legal claim depends on the facts. A free, no-obligation case review will tell you where you stand — there is no cost and no commitment to find out.
