The Pfizer-BioNTech coronavirus vaccine appears to be highly effective against a more-contagious variant first discovered in Brazil, according to a new study published in the New England Journal of Medicine, raising hopes that ongoing vaccination efforts will help curb its spread.
The findings have not been confirmed by real-world data, but they come as public-health experts warn that the more-transmissible variants could drive yet another surge in coronavirus cases, particularly as restrictions are lifted across the United States.
As health officials rush to get ahead of the variants, Congress is on track to pass pandemic relief legislation after months of debate, with the House set to begin consideration of the $1.9 trillion package at 9 a.m. Wednesday. Once passed, President Biden will sign the measure into law.
