"We will never be fully vaccinated against Covid-19." "You need to get vaccinated every 9 months!"

"We will never be fully vaccinated against Covid-19."
Health Minister Jean-Yves Duclos (an economist who shouldn't be a Health Minister) says Canadians need to be "up-to-date" on their vaccines, which he describes as getting the Covid vaccine every nine months. This is not the way a vaccine works, every 9 months? what?????

From Wikipedia:
"Duclos attended the University of Alberta, where he earned an undergraduate degree in economics, followed by graduate and doctoral studies in economics at the London School of Economics. His doctoral thesis in 1992 was titled "Progressivity, equity and the take-up of state benefits, with application to the 1985 British tax and benefit system".[1] Prior to his election to the House of Commons, he headed the economics department at Université Laval and was the president-elect of the Canadian Economics Association. "
Is this an economic decision or a health deicision?

The Trudeau Cabinet is filled with the most unqualified and inappropriate people and WEF pawns!
