The US and lots of different nations already have been urging adults to get booster pictures to pump up immunity that may wane months after vaccination, calls that intensified with the invention of the worrisome new omicron variant.

On Thursday, the Food and Drug Administration gave emergency authorisation for 16- and 17-year-olds to get a 3rd dose of the vaccine made by Pfizer and its associate BioNTech — if it’s been six months since their final shot.
