Fauci pushes for universal coronavirus vaccine

Writing in the New England Journal of Medicine, Fauci and two colleagues said the virus that causes Covid-19 is unlikely to be eliminated, and current vaccines are too limited to prevent the emergence of new variants. Other coronaviruses are also likely to spill over from animals to become future pandemic threats, they wrote.

To overcome these problems, the authors argue the research world should “fully commit” to developing a “second-generation” of coronavirus vaccines that would provide broad protection across the genetic spectrum of coronaviruses. They suggest forming an international effort to collect animal coronavirus samples worldwide and developing ethical challenge trials for coronaviruses, among other measures.

During the past two decades, the world has seen four deadly coronavirus outbreaks, including two bouts with SARS in the early 2000s, the emergence of MERS in 2012 and now Covid-19, which has killed more than 800,000 Americans.

The commentary offers no quick fix for the pandemic. But Fauci’s endorsement of the universal vaccine approach could serve as a clarion call and blueprint for scientists.
