Nadhim Zahawi, the minister responsible for the vaccine rollout, said despite "lumpy" vaccine supply, he was "confident" that Britain is able to vaccinate all 15 million people in the top four priority groups by mid-February.
On Sunday, British Foreign Secretary Dominic Raab said every adult in Britain is expected to receive at least one dose of a vaccine by September.
However, with deaths and cases remaining high, it is believed that Britain will still be under tight restrictions for the next few months.
England is currently under the third national lockdown since the outbreak of the pandemic in the country. Similar restriction measures are also in place in Scotland, Wales and Northern Ireland.
To bring life back to normal, countries such as Britain, China, Germany, Russia and the United States have been racing against time to develop coronavirus vaccines.
