The warning of an imminent surge came even as federal officials and some pharmaceutical executives signaled that they don’t currently favor creating an omicron-specific vaccine. Based on the data so far, they say that existing vaccines plus a booster shot are an effective weapon against omicron.
The CDC briefing Tuesday detailed two scenarios for how the omicron variant may spread through the country. The worst-case scenario has spooked top health officials, who fear that a fresh wave, layered on top of delta and influenza cases in what one described as “a triple whammy,” could overwhelm health systems and devastate communities, particularly those with low vaccination rates. ...
Officials stress that early data shows that individuals who are fully vaccinated and received a booster shot remain largely protected against severe illness and death from omicron. But they worry about how few Americans have been boosted to date. Over 55 million people in the United States have gotten the additional shots, out of 200 million who are fully vaccinated, according to the CDC.
The newest modeling scenarios have been shared among senior administration officials as they discuss politically fraught decisions about how, when and whether to take new steps to suppress the virus and keep hospitals from being overwhelmed.
The second scenario outlines a smaller omicron surge in the spring. It’s unclear which scenario is more likely. The modeling was done by experts tapped by CDC Director Rochelle Walensky in August to deliver real-time outbreak forecasting and analytics. The experts work with other teams inside and outside the government. ...
Late Tuesday, after this story was published online, the CDC released a statement saying the morning discussion was part of a regularly scheduled meeting, hosted by the agency, with leaders of four public health organizations. “As we are preparing for a range of scenarios with the Omicron variant, a portion of the meeting was dedicated to discussion around results from various modeling groups related to Omicron—no CDC, HHS or U.S. Government models were presented,” the statement said. ...
