While leading vaccines continue to provide high levels of protection against COVID-19, the delta form is proving to be their most difficult enemy yet. The fourth major variety is driving Canada’s fourth wave. It is highly contagious and potentially capable of producing astounding virus quantities inside the human body. It also increases the likelihood that more Canadians, vaccinated or not, maybe exposed to the virus in the coming weeks and months.
“It’s something we’re all going to have to deal with at some point,” said Dr. Zain Chagla, an infectious diseases specialist at McMaster University in Hamilton.
“I think everyone unless they’re staying at home in a complete lockdown lifestyle, will have exposures.”
This indicates that case counts will likely continue to grow for some time, including “breakthrough” infections among fully vaccinated persons as the delta variation spreads and vaccination rates gradually increase. However, disaster is not unavoidable.
According to experts, maintaining certain measures will help protect both vaccinated and unvaccinated people, including millions of Canadian children, by preventing some possible transmission. And getting infected by this aggressive form after vaccination doesn’t indicate you’ll end up extremely ill or dying from COVID-19 — in fact, the most recent evidence shows it’s still improbable.
“You will have a big number of unvaccinated people getting quite sick, and even people who are vaccinated will become sick,” said Dr. Andrew Morris, an infectious disease expert at Sinai Health System in Toronto.
“How many individuals will die in the next months will be primarily determined by government action and public health initiatives.”
