Half of all 16 and 17-year-olds have already got their Covid vaccine, NHS England revealed today.
Latest figures showed 620,000 teenagers in the age group are registered as having received one dose.
It comes less than a month after the JCVI — which is advising Britain's roll out — recommended they were inoculated.
Officials said appetite for jabs among young people had been 'strong' since the drive began at the start of August.
Separate data from Public Health England (PHE) showed vaccines have already prevented 140,000 hospitalisations across the country.
The agency's weekly report highlights just how well vaccines are already working at preventing serious disease and death, amid mounting calls for a booster programme to be launched.
Experts are warning England faces a third wave of infections as schools return this week and next. No10's top scientists are still deliberating on whether to roll out jabs to 12 to 15-year-olds.
