Bill Gates, in a Twitter discussion Tuesday, said that the current COVID-19 vaccines were missing two key factors, and claimed that Omicron might bring about a wave of immunity in communities it passes through.
Microsoft co-founder and one of the world’s richest men, Gates has invested in vaccine research through his foundation and given prominent talks regarding the pandemic. Recently, he chatted regarding the current situation of COVID-19, vaccines, and related issues with Devi Sridhar, a professor at the University of Edinburgh where she holds a Personal Chair in Global Public Health.
When asked about a breakthrough that could result in the biggest difference in ending the pandemic, he talked about the efficacy of vaccines.
“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,” Gates said.
The effectiveness of vaccines has been questioned, especially with regards to the Omicron variant. The high number of mutations on the variant’s spike protein increases “the possibility of immune escape,” according to Moderna President Stephen Hoge. Hoge added that the “dent in our vaccine’s efficacy” applies to all manufacturers.
Omicron has spread rapidly across the world, with 98.3 percent of infections in the United States now attributed to it. Although highly transmissible, international studies have shown that the strain poses milder symptoms in infected people.
Recently, a notable international health charity called for treating COVID-19 “like the common cold.” Dr. Mike Tildesley, a University of Warwick professor, has forecast COVID-19 evolving to become less severe and endemic. He said the Omicron variant is the beginning of that process. Gates has seconded this perspective.
“Once Omicron goes through a country then the rest of the year should see far fewer cases so COVID can be treated more like seasonal flu,” he said, while recommending yearly COVID-19 shots that would be needed for some time.
Gates talked about a lot of “misinformation” regarding him spreading on social media. “People like you and I and Tony Fauci have been subject to a lot of misinformation. I didn’t expect that. Some of it like me putting chips in arms doesn’t make sense to me—why would I want to do that?”
