The first Covid-19 Vaccines will begin to be administered to people in Northern Ireland today.
Around 12,500 people are expected to get the jab there this week.
People aged 80 and over, care home workers and some healthcare staff are first in line to get immunised.
Meanwhile in the U.S. Donald Trump's personal lawyer - Rudy Giuliani - has tested positive for Covid-19.
The 76-year-old has been representing Mr Trump's baseless claims of voter fraud in the recent US election.
