COVID vaccines are now mandatory for some citizens and government employees in a move by President Biden which USSC CEO Professor Simon Jackman told Sky News Australia is opening up a new front in an already divided America.

“Already, there was tremendous partisan division in the US around acknowledging COVID as a crisis, around mask mandates. And now this is going to another level with vaccine mandates," Professor Jackman said.

Court challenges to the decision should be expected to come in the months ahead, warned Professor Jackman.
