@devisridhar mRna vaccines still can't meet all the demand so figuring out who gets what is complicated.#

@devisridhar During 2021 the supply of vaccines was limited and they mostly went to wealthy countries. Now we have a lot of supply overall and the problems are logistics and demand. The health systems in developing countries are a limiting factor.

@devisridhar The vaccines we have prevent severe disease and death very well but they are missing two key things.

First they still allow infections ("breakthrough") and the duration appears to be limited.

We need vaccines that prevent re-infection and have many years of duration.#

I'm excited to talk with @DeviSridhar today about her work at the University of Edinburgh Medical School and @GlobalHealthGP, and to answer some of your questions about what we’ve been learning recently about the pandemic. #

Through my foundation work I'm very lucky to have the opportunity to talk to—and learn from—experts in many different fields. Many of my conversations recently have been about the omicron variant and how to prevent the next pandemic. https://t.co/jYR0KjX4Cx

Understanding how the connections in our brains give rise to consciousness and our ability to learn may help lead to great breakthroughs in the way we solve the world’s hardest problems. This is one of the most fascinating books I read this year. https://t.co/UaSQV1jbBg

.@WalterIsaacson is one of my favorite authors. I was eager to read his latest book about CRISPR and its inventor Jennifer Doudna: https://t.co/qD9QASvwHx https://t.co/ZiWiKjVjCq

Heroes like @PumlaNtlabati are spreading important information, and hope, across South Africa with the help of an unusual and innovative tool: https://t.co/vBSMvpv6Lt https://t.co/euBp7fM2PF

We have some, but not all, of the tools we need to hit our target of limiting global warming to less than 2 degrees. We need to prioritize closing that gap if we’re going to avoid a climate disaster: https://t.co/h6wqiZVgph https://t.co/Mj3df3OVl0
