Quebec has become the second Canadian province after Alberta that will no longer provide free vaccination against COVID-19 for all its population.

Instead, only certain categories of people will still receive the shot at no cost: seniors, health care workers, residents of remote regions and medically vulnerable patients.

Smoke from Canada’s record-breaking 2023 wildfire season may have led to more than an estimated 82,000 premature deaths globally, according to a new study.

The study, published in the scientific journal Nature on Wednesday, highlights the far-reaching impact of pollution and associated deaths caused by the Canadian fires, primarily in North America and Europe. Researchers concluded that more than 354 million people worldwide were exposed to Canada’s wildfire toxins.

Albertans who are not eligible for a free COVID-19 vaccine this fall will have to pay $100 to get a shot, the province announced Friday as it outlined another change to its highly scrutinized immunization program.

Alberta will be the only province in the country to make most of its residents pay out of pocket to get immunized against COVID-19 this October. Health care workers, immunocompromised individuals, seniors in care homes or receiving home care, and people on income support will continue to be covered by the province. The $100 administrative fee applies to all other Albertans.

Newly released documents paint a picture of how Alberta’s measles outbreak began with a handful of isolated cases and started to grow into what is now the worst in North America, as public-health measures to control spread in some cases proved ineffective.

The documents, obtained through a freedom of information request, offer the most detailed illustration yet of the early days of Alberta’s measles outbreak and how the government impeded some health officials’ efforts to stop it.
