All older teenagers in England will be offered their first vaccine by August 23 in a bid to get them some protection before starting school or college next month.
Vulnerable children aged 12 to 15 will also be contacted by GPs in the coming days and invited for their jab.
Health leaders are encouraging more London teenagers to come forward with 45,000 letters being sent out to teenagers explaining how to get the injection at their nearest walking centre.
Some 14,476 people aged 16 and 17 in London have had their vaccine. Nationally, more than 360,000 teenagers in the age group have been jabbed.
Joint Chief Nurse for the NHS in London, said: “I am pleased to see that 16 and 17 year olds across the city are coming forward for their jab, protecting themselves, their friends and their loved ones.
“The vaccine is proven to be safe and effective, and with hundreds of vaccine walk-in, pop up and booked appointment services across London I urge everyone who is eligible to come forward as soon as possible.”
Health and Social Care Secretary Sajid Javid added: “It is excellent to see the enthusiasm young people have shown to get a Covid-19 vaccine and help to build our wall of defence against this virus.
“I urge you to join the hundreds of thousands of 16 and 17 year olds who have already taken up the offer of vaccine as quickly as possible to ensure you get vital protection before returning to college or sixth form.
“Please don’t delay – vaccines are allowing us to live safely with this virus without restrictions and enjoy our freedoms.”
