Canadian Prime Minister Justin Trudeau is back in quarantine after testing positive for COVID-19 for the second time this year – and insisting it would be worse if he was not vaccinated and boosted.

Trudeau, who went into isolation in January, just as the nation’s truckers converged on Ottawa to protest his government’s strict vaccine mandates, announced his latest positive test Monday. He said he was feeling “okay,” and expressed gratitude that he was vaccinated.

“I’ve tested positive for COVID-19. I’ll be following public health guidelines and isolating,” Trudeau said. “I feel okay, but that’s because I got my shots. So, if you haven’t, get vaccinated – and if you can, get boosted. Let’s protect our healthcare system, each other, and ourselves.”

Just last week, Trudeau was in California where he met with Democratic President Joe Biden, House Speaker Nancy Pelosi (D-CA), Gov. Gavin Newsom (D-CA), and other officials. None of the U.S. officials have announced that they have been infected.

Although the COVID vaccines were originally advertised as providing significant protection from infection, many media outlets now say they are “primarily designed to keep those who become infected from falling seriously ill,” according to The Associated Press.
