QUEBEC -- A Quebec pharmacist and blogger has won a prestigious international prize for standing up for science.

Olivier Bernard, also known as "The Pharmafist," has been awarded the John Maddox Prize in London for his work in debunking myths around the use of vitamin C to treat cancer.

In 2018, Bernard became aware of a petition circulating in Quebec that was asking the government to approve large injections of the vitamin on the theory that it helped cancer patients.

Bernard checked into the science behind the claim and found that it was highly dubious.

He says he and his wife suffered strong social media backlash, including threats, when he published his findings on his blog and broadcast them on his TV show.

The petition was rejected after doctors and scientists in Quebec came to his defence.
