Does the AstraZeneca Vaccine Also Stop Covid Transmission?
Wired - 11/30/2020
A model built by Sam Scarpino, director of the Emergent Epidemics Lab at Northeastern University, suggested that a switch back to the old formulation would lead to a significant drop in deaths and illnesses. Given the speed and severity of the Covid-19 pandemic, the importance of this effect could be even greater. “Especially in a country like the US with so much vaccine hesitancy, and coupled with how severe the disease can be especially in older adults, transmission block is a huge deal,” Scarpino says. “We don’t have any reason to think the Pfizer and Moderna vaccines won’t block transmission. It’s just not what has actually been measured, and something we aren’t likely to find out until we either start mass vaccination and/or they release more detailed information on the study locations—and epidemiologists start looking for effects of herd immunity.”
