Britain's health ministry has said it would open up bookings for booster shots a month before people were eligible to receive the shots to help speed up the rollout ahead of the challenging winter months.

Currently, people can only book the appointment six months after their second dose, according to a Reuters report.

“This will accelerate the booster programme, ensure the NHS is able to vaccinate people as quickly as possible, and importantly help more people maintain protection against Covid-19 as we know immunity will dip over time,” Health Secretary Sajid Javid, who sets policy in England, said.
