Stuart Nash says you'd have to be a nutter not to take the Covid-19 vaccine.

That's the stern word from the Labour MP, as MedSafe reviews the Pfizer vaccine's clinical data.

Provisional approval could come today,  but roll-out isn't set to start until about April - firstly for at-risk border staff.

Nash says the Prime Minister will address the nation this afternoon.

"There'll be enough vaccines for every Kiwi - and while Government can't make it compulsory, he would if he could."

Listen to the audio above as Stuart Nash and Mark Mitchell join the Mike Hosking to discuss the issues making news this week.
