Scary Strain: Omicron's Record Spread Keeps World Worried. Are Vaccines & Treatment Working?

The omicron variant now makes up 3% of all sequenced Covid-19 cases in the U.S., rising from less than 0.1% in early December, health officials said, a sign of the rapid spread of the new coronavirus version.

The highly mutated variant has now been detected in 33 U.S. states, the Centers for Disease Control and Prevention said in an email. While the delta variant remains the dominant strain in the country, accounting for 96% of sequenced cases, omicron’s proportion is expected to increase, agency spokesperson Jasmine Reed said.

Countries around the world are working to respond to the spread of omicron, a variant that appears to have mutations that may allow it to evade the effects of some vaccines. South African researchers said Tuesday that standard courses of vaccines from Pfizer Inc. and BioNTech SE or Johnson & Johnson prevent as much as 70% of Covid hospitalizations and deaths.

Omicron was first identified in South Africa and classified by the World Health Organization as a variant of concern last month. The CDC is working closely with state and local health officials to monitor its spread, Reed said.

The World Health Organization says the strain is spreading at a rate not seen with any other Covid variant at a global scale. New data from South Africa's largest private insurer show two doses of the Pfizer vaccine are less effective against severe disease with Omicron than previous variants.
