Unvaccinated people increase infections

A study published in the Canadian Medical Journal says that unvaccinated people increase the risk of COVID-19 infection among the vaccinated. So – as was suspected all along – choosing not to be vaccinated isn’t just about managing a risk to oneself, but to everyone one comes in contact with.

CTV writes a dubious headline here: “Experts advise Canadians to consider personal risk before getting 4th COVID vaccine dose.” But this is about the risk of catching Covid, not risks from the vaccine itself, which some might assume is intended. The article is actually quite informative about the debate over how long we should wait for a second booster after either having the first, or being diagnosed with Covid.
