Bill Gates says COVID-19 vaccines are 'missing two key things'
Novavax CEO says company at ‘tipping point’ with COVID vaccine
Novavax CEO Stanley Erck says the company is in the process of manufacturing ‘quite a bit of doses and getting them out’ and notes that the vaccine will be ‘very effective’ against the omicron strain.
Bill Gates, who donated $1.75 billion to COVID-19 vaccine development and fighting the pandemic, said this week that while the currently available vaccines prevent severe illness and death, they aren't durable enough and should be better at preventing infection.
The Microsoft founder, whose net worth Forbes pegs at $135.9 billion, made the comments in a Twitter discussion with Devi Sridhar, the chair of global public health at the University of Edinburgh Medical School.
"The vaccines we have prevent severe disease and death very well but they are missing two key things," Gates said to a question about what would make the biggest difference in ending the pandemic.
"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."
