Co-author David Fisman, of the University of Toronto’s Dalla Lana school of public health, said the message of the study is that the choice to get vaccinated can’t be thought of as merely personal. Fisman said that in real life, people tend to spend the most time with people who are similar to them. So, he said, even if vaccinated people are most likely to spend time with others who have received shots, they’re disproportionately impacted when they spend time with those who haven’t.
While remaining unvaccinated against COVID-19 is often framed as a personal choice, those who spurn the vaccines raise the risk of infection for those around them, a new study suggests. “You may like to drive your car 200 kilometres an hour and think that’s fun, but we don’t allow you to do that on a highway partly because you can kill and injure yourself, but also because you’re creating risk for those around you,” he said in a recent interview.
He said the arrival of more contagious COVID-19 variants, such as Omicron, have impacted both vaccine effectiveness and public faith in vaccination. But he said that even when vaccine efficacy was lowered to 40 per cent in the model and the reproductive rate was increased to account for a more contagious variant the overall conclusions were the same.
The research published Monday in the Canadian Medical Association Journal found that vaccinated people who mix with those who are not vaccinated have a significantly greater chance of being infected than those who stick with people who have received the shot.
