The greatest medical breakthrough of this pandemic is the creation of COVID-19 vaccines that use mRNA. Here are 4 steps to develop, manufacture, and distribute vaccines even faster next time. https://t.co/cJylwQvbBQ

To meet the world’s climate goals, clean energy technology needs to be affordable, attractive, and accessible to all. https://t.co/R04oAdC2ka

Just like we have a robust system to prevent and extinguish fires, there needs to be an equally effective system to identify and respond to disease outbreaks. This firefighting comparison is a useful way to understand the amazing work of @sofoniaskt: https://t.co/QlXHoJtHGT https://t.co/VUBcBVGFVu

I can’t believe this was 15 years ago. I always enjoyed the @allthingsd conference. https://t.co/L4fIBNYNPU

@waltmossberg @Kodak Reconnecting with Steve was fantastic. And for the record, I wasn’t reluctant to take the photo. But I do wish I had an opportunity to run a comb through my hair first.

I recently met with 33 graduate students and a few leading scientists about how to make sure disease outbreaks don’t go global: https://t.co/nDHQh9sOLE https://t.co/3DSbMvnO7V

While there are many great commencement speeches, I found this one from my friend Reid particularly insightful. https://t.co/AHkDOwHGoF

@mansukhmandviya It was great to meet Dr @mansukhmandviya and exchange perspectives on global health. India's success with the vaccination drive and the use of technology to drive health outcomes at scale offers many lessons for the world.

Happy to meet Prime Minister @sanchezcastejon and members of his government today in Madrid. Great to see his leadership and commitment to addressing some of the most pressing global challenges, particularly more equity in global health, climate change and food security. https://t.co/gCUdvKr4jj
