Former U.S. President Donald Trump has urged his supporters to get vaccinated against the COVID-19 as concern grows amid polls showing hesitation on vaccinations by the GOP.

In an interview with Fox News, Trump said he would recommend vaccines currently being distributed. 

He said he would recommend vaccination to "a lot of people that don't want to get it, and a lot of those people voted for me".

"We have our freedoms and we have to live by that and I agree with that also," he said.

"But it is a great vaccine. It is a safe vaccine and it is something that works," he added.
