A mass vaccination centre in Tokyo will begin booking Covid-19 shots for people under 65 years old from Saturday, reported the Sankei newspaper, as Japan ramps up efforts to inoculate people before the 2020 Olympics open next month.

The Tokyo vaccination centre will also begin taking appointments by telephone for the first time from Saturday, in addition to online bookings in a bid to encourage more people to use the centre, the Sankei reported.

With less than 50 days before the Olympics open, Japan has vaccinated just over a tenth of its population with at least one dose.
