We're excited to announce a two-part webinar series dedicated to the Vaccine Vial Monitor (VVM), the simple yet transformative tool that has helped ensure vaccine potency worldwide for three decades.

• Session 1: 30 Years of VVM: A Retrospective
  Join us for a look back at three decades of the VVM, from its initial development and validation through to its global scale-up. We'll review the key milestones, the science behind the technology, and how it nearly didn't happen.

 📅 Date: Thursday 29 October 2026
🕐 Time: 10:00-11:00 CET - Geneva time (UTC+1)

• Session 2: The New VVM App
  In this session, we'll introduce the new VVM App, developed in collaboration with the World Health Organization (WHO). The app is designed to optimise vaccine administration and distribution by making VVM monitoring more actionable in the field. You can find the App by searching "Vaccine Vial Monitor" on the Google Play Store or Apple App Store.

Both sessions will include a live Q&A, and automatic written Zoom translation (video caption) will be available in several languages. 

 📅 Date: Thursday 5 November 2026
🕐 Time: 10:00-11:00 CET - Geneva time (UTC+1)
