Covid: Did Pfizer's boss cast doubt on his own vaccine?
Jerome doesn't follow news closely on Twitter, using the site mainly to tweet about sports and books he's enjoying.
The 41-year-old bus driver, from Quebec has mostly supported local Covid restrictions, although he admits to growing "fed up", two years into the pandemic.
His feed reveals him mildly grumbling about his children's home-schooling, among posts about favourite authors and Canada's national football team.
But casually scrolling on the social-media site, one Monday early in the new year, he came across a video clip appearing to show the head of Pfizer suggesting his vaccine provided no protection at all against Omicron.
Albert Bourla could be seen saying: "We know that the two doses of the vaccine offer very limited protection, if any."
But the clip had been taken out of context from a longer interview, with Yahoo Finance, in which Mr Bourla had been discussing high infection rates with Omicron.
