Unvaccinated People Increase Risk for Vaccinated People

I can’t say that I’m surprised.
Remain­ing unvac­ci­nat­ed increas­es risk to the vac­ci­nat­ed, says U of T COVID study

Peo­ple who are unvac­ci­nat­ed against COVID-19 not only place them­selves at greater risk of get­ting infect­ed by the virus, but also increase the infec­tion risk of those around them who have rolled up their sleeves for a jab, accord­ing to new Cana­di­an mod­el­ling research.

The find­ings, pub­lished Mon­day in CMAJ (Cana­di­an Med­ical Asso­ci­a­tion Jour­nal), sug­gest the choice to remain unvac­ci­nat­ed affects the infec­tion risk among vac­ci­nat­ed peo­ple “in a man­ner that is dis­pro­por­tion­ate to the por­tion of unvac­ci­nat­ed peo­ple in the pop­u­la­tion,” the authors write.

The mod­el­ling showed these find­ings held true even when COVID vac­ci­na­tion rates are high, said Dr. David Fis­man, the study’s lead author and pro­fes­sor of epi­demi­ol­o­gy at the Uni­ver­si­ty of Toronto’s Dal­la Lana School of Pub­lic Health.

“What we see under the (mod­el­ling) con­di­tions, which look a lot like the COVID epi­dem­ic at the moment, is the risk for vac­ci­nat­ed indi­vid­u­als is dri­ven dis­pro­por­tion­ate­ly by their inter­ac­tions with unvac­ci­nat­ed indi­vid­u­als,” Fis­man said in an inter­view. “This belies the idea that (vac­ci­na­tion) is just an individual’s per­son­al choice that doesn’t affect any­one else.”
