In France, 52.5 million people are fully immunized i.e. 78% of the total population of the country. But, some still refuse to be vaccinated against Covid-19. However, according to a recent study, this decision would involve the whole entourage.

Indeed, not being vaccinated would also impact those who have been vaccinated against Covid-19 according to the conclusions of a Canadian study. Specifically, those who are not vaccinated increase the risk of catching the virus from vaccinated people. To reach these conclusions, scientists from the University of Toronto (Canada) have developed a mathematical model allowing to estimate the risk of contamination in several situations. A way to differentiate between cases where the entire population has the same vaccination status and cases where vaccinated people rub shoulders with those who are not. These findings were published in the journal of the Canadian Medical Association.

A choice that is not personal
“When the vaccinated are not exposed to the unvaccinated, their risk is very low,” the authors found. They noted a peculiarity: “When everyone comes into contact, a substantial number of vaccinated people are infected”. For the authors of this study, vaccination should therefore not be considered as a purely personal choice : “We cannot therefore advance the argument of individual choice without impact other than on oneself”.

For David Fisman, of the Dalla Lana School of Public Health at the University of Toronto, co-author of this study, the choice to get vaccinated cannot therefore be formulated as simply personal: “You might like to drive your car going 200 kilometers an hour and thinking it’s fun, but we don’t allow you to do that on a freeway partly because you can kill and hurt yourself, but also because you create a risk for those around you”.
