Nearly 15 million people in the US have missed their second dose of the coronavirus vaccine, handing an intriguing problem to the authorities amid varying immunisation timelines and the spread of the highly transmissible delta variant, according to media reports on Sunday. As of June 16, nearly 11 per cent of vaccine recipients in the US have not taken their second dose, The Washington Post reported quoting data from the Centers for Disease Control and Prevention.
The second dose is considered ‘missed’, if 42 days have elapsed since the first shot, the newspaper reported. Ideally, the second jab is advised three weeks after the first Pfizer-BioNTech shot or four weeks after the first Moderna shot.
