To kick-off the conversation with @BillGates, what scientific or tech breakthrough would make the biggest difference now to ending the COVID pandemic?
@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.#
@BillGates Agree 100%- next gen vaccines with sterilising immunity. 2nd question: What are the current challenges in reaching global vaccination access? What are the obstacles?
@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 mRna vaccines still can't meet all the demand so figuring out who gets what is complicated.#
@BillGates There's been a lot of discussion on responsibility of pharma companies like Pfizer/Moderna for access. What is the role of these companies in ensuring pricing and availability esp in low and middle income contexts?
