SPECIAL GLOBAL MEDIA BRIEFING Topic: Getting your head around the vaccine data

Organized in collaboration with the Australia, New Zealand, UK, USA, Germany, Japan, Israel, Taiwan, Philippines, Thailand, Singapore, Austria, France, Indonesia and Hong Kong media centers.

As the Delta variant becomes dominant around the world, fully vaccinated people are becoming infected with COVID-19. These so-called ‘breakthrough infections” have raised questions about the effectiveness of the vaccines. Data from some countries with high vaccination rates are also now showing more weekly cases of COVID-19 in vaccinated people than in the unvaccinated – does this mean the vaccines aren’t working? Join some of the world’s leading vaccine experts at this briefing from the global Science Media Centres and our partners in the COVID-19 Vaccine Media Hub. The briefing will discuss the following issues: How can we make sense of the vaccine efficacy data? Just how effective are the vaccines against the Delta variant? Do the vaccines prevent transmission? Can any countries actually reach herd immunity? Will we need booster shots in the coming months?

Date: Thu 2 September 2021
Start Time: 11:00 AM East Africa Time ,18:00 Australian Eastern Standard Time, 09:00  Central European Time, 04:00 US Eastern Time
Duration: Approx. 45 min
Venue: Online- Zoom
