"If there is a safe and useful vaccine, the government can force you to take it," Greely told TMZ.

It could be forced through public schools or businesses owned by the government that could require people who enter the building to have the vaccine.

For Americans who don't want to vaccine due to concerns of it not being safe and rushed, Greely says their argument won't really hold up in court if the FDA approves it.

Others who oppose vaccines in general or those who politicize the vaccine would also have trouble fighting to get back into work or school if a safe and tested vaccine is required.

A recent Gallup survey found that only 65% of Americans would get the coronavirus vaccine if it was available today.

A total of 35 per cent said they would not, but a higher percentage of minorities, who have been shown to be disproportionately impacted by coronavirus, said they were opposed to taking a vaccine.
