The COVID vaccine became a flashpoint during the pandemic and people have continued to speak out about the side effects of the vaccine. Adverse side effects have been reported since the rollout of the COVID-19 vaccine and some people have died. However, the Centers for Disease Control and Prevention (CDC) maintains that the vaccine's benefits outweigh the risks and that severe reactions are rare.
Jeckov Kanani, who has been an outspoken critic of Canada's COVID response, posted a video of the mayor's collapse on X, and encouraged people not to take the vaccine. He added that people shouldn't get the booster, either. Others posted that this should be a "wake up call" and used the hashtag "vaccine side effect." The Telegram account "Vaccine Injuries" also posted about the mayor's collapse.
Plante confirmed in December 2021 that she was double vaccinated against COVID-19. Despite claims from social media users, Plante's office confirmed to Newsweek that the sudden collapse was not due to the vaccine.
