Scientists race to answer the question: Will vaccines protect us against omicron?

NPR  

Scientists race to answer the question: Will vaccines protect us against omicron? In essence, they took about 20 mutations and put them all together onto one spike protein, which they call a "polymutant spike mutant." "Omicron appears to have certain combinations of mutations that together would confer more pervasive resistance to individual classes of antibodies," he says. "This polymutant spike protein was almost completely resistant to the neutralizing antibodies in those two sets of plasmas," Bieniasz says. "Based on those findings, we expect that omicron will be significantly resistant to antibodies that are circulating in individuals who have convalescence or who have had mRNA vaccines," Bieniasz says.
