In the coming days, Pfizer is expected to brief top U.S. government health officials in the coming days about the need for a coronavirus vaccine booster shot after an unusually public spat between the pharmaceutical giant and federal officials over whether a third shot will be necessary, according to the company and six people familiar with the plans.

But top U.S. health officials have not decided whether boosters will be necessary. And several hours after the companies announced their intentions Thursday, the Department of Health and Human Services (HHS) issued an emphatic rebuke, saying "Americans who have been fully vaccinated do not need a booster shot at this time."
