In an opinion piece, Roxanne Khamsi, a science journalist covering the COVID-19 pandemic, says that “throughout the pandemic, there have been various kinds of medical anomalies,” such as “people who test positive for months and others who never get infected despite living in close quarters with Covid sufferers.” Khamsi writes that “such surprising cases are often declared ‘outliers’ and shrugged off (and, indeed, should be downplayed when designing public health policies for the general population), but unusual examples of any disease can offer important insights for scientists, and most critically, lead to new medicines for that illness and others.” NIBIB immunologist Kaitlyn Sadtler is quoted as saying, “The complexity of the immune system cannot be overstated. … It makes it amazingly effective but amazingly difficult to understand.” Source: New York Times
