UK Prime Minister Boris Johnson has announced the country will roll out a second COIVD booster jab.
Johnson made the announcement at the Conservative spring conference in Blackpool on Saturday (local time) but didn't give any timeframe around the rollout.
However, UK Health Secretary Sajid Javid told ITV earlier this week the fourth jab for the entire population would be rolled out in autumn, ahead of the winter season when there is an increase in viral infections.
The UK government had previously announced last month the fourth jab would be offered to over-75s, care home residents and the immunocompromised in the coming weeks.
Johnson praised the UK public for their uptake of the COVID vaccines saying they were "fed up with being told what to do, by people like me".
"The British population came forward to be vaccinated at such incredible speed voluntarily, unlike many other countries," Johnson said.
"I'm sure it was partly because they wanted to avoid catching COVID - a very sensible thing to do, by the way.
"Why did the British people come forward - 90 percent, entirely voluntarily?
"It was because they wanted to get on with their lives. They were fed up with being told what to do, by people like me.
"We wanted to take back control of our lives."
Johnson had previously announced in February he would end all coronavirus restrictions in England including mandatory self-isolation for people with COVID-19 and free testing.
The legal requirement to self-isolate for people who test positive for COVID was removed on February 24 while free universal testing will end on April 1.
