Moderna's CEO does not hide fears about the Omicron variant of Covid and terrifies everyone. Stephane Bancel said in an interview with the Financial Times that he predicts the existing vaccines will have a hard time with the Omicron variant. In a speech to Cnbc, he added that it will take months to develop and ship a vaccine specifically targeting the Omicron variant of the coronavirus. However, a dose higher than 100 micrograms of Moderna's booster may be ready much sooner. "The higher dose could be done right away, but it will take months before the Omicron-specific variant is ready for shipment in bulk quantities," Bancel said. Inside Moderna they believe the variant is highly contagious, but it will take at least two weeks to determine how much the mutations have affected the effectiveness of currently marketed vaccines.

And of course he already knows new vaccines are needed
