We do not know yet how well the current MAbs will work for the omicron variant, but we will know very soon how well they neutralize omicron in the lab, Bollinger says. Scientists' portrait of Omicron is still blurry and it will take weeks before they can fully assess its properties. There is some preliminary evidence suggesting the omicron variant is more infectious than the delta variant, says Bollinger. Predict the closing value of sensex and win free subscription. Most people experience cold-like symptoms. Severity: Studies have suggested the B.1.1.7 lineage was more likely to land infected people in the hospital and was deadlier than the original virus.
