The exact level of immunity acquired from a natural infection is yet to be fully determined, says Dr. Andre Veillette, a professor of medicine at McGill who's also on Canada's COVID-19 vaccine task force.It may be that protection begins to wane quicker in some people, or that those with previous mild infections aren't as protected as someone who had more severe symptoms, he says.
But there are still questions around whether the vaccines can actually prevent someone from catching the virus and spreading it to others. While Moderna has some data that their product may protect against acquiring the virus, it's still unclear. Kerfoot, an associate professor at Western University, says vaccines are designed in a way that should produce an immune response "at least as good or better" than what we get after a natural infection.
Even studies suggesting an early drop-off of antibody levels aren't concerning, Kerfoot says. Infections trigger the body to produce other immune cells and memory cells that reduce slowly over years and help fight off future invasions from the same virus. "I don't think we can use prior infection as an indicator of priority, because we just don't know what that person's immune response actually is," Kindrachuk said. "We don't know what long-term immunity looks like in those folks.
Media drives public opinion and gets politicians moving. Pressure JustinTrudeau and dougford to do better... its chaos out here. I'm looking at canadas greatest failure to it's people by both levels of government. ColinDMello
Too much people are falling ill from it hahahaha shove that vaccine up your ass
Oh yes, of course. 🙄 Because our God given IMMUNE SYSTEM never works. That's why 'gods' like Fauci gave us the Vaccine...(as well as the virus to begin with.) Shove the Vaccine up you ass, CTV. You CPP controlled rag. 🖕
Everyone needs to get a vaccine that does not stop you from contacting or spreading the virus. Makes no sense.
That’s 95% of the population because Trudeau is way too slow sourcing vaccines. By the time it’s available most Canadians will have already had Covid
Not to worry liberal failure doesn't have the vaccine coming for a long time yet.

I thought you were pro science
CTV news is not a reliable source of unbiased news, experts say.
great now give it to us
They're not experts, they're propagandists
Agreed, but the $1-million question.........when might that be? At the rate Ontario and fordnation JustinTrudeau are going, it will be far-far-far away.
