Oil falls 3% on jitters over vaccine efficacy

SINGAPORE/LONDON: Oil prices tumbled more than 3% on Tuesday after Moderna’s CEO cast doubt on the efficacy of COVID-19 vaccines against the Omicron coronavirus variant, spooking financial markets and adding to worries about oil demand.
The head of drugmaker Moderna told the Financial Times that COVID-19 vaccines are unlikely to be as effective against the Omicron variant of the coronavirus as they have been against the Delta variant.
