Unvaccinated people increase the Covid risk of vaccinated people: study

Unvaccinated people threaten the safety of people vaccinated with COVID-19, even with high immunization rates, according to a modeling study published on Monday.

Researchers at the University of Toronto, Canada, are simple to investigate the effects of a mixture of unvaccinated and vaccinated people to understand the dynamics of infectious diseases such as SARS-CoV-2. I used a model.

They simulated a mixture of similar populations in which people have exclusive contact with other people in the same vaccination situation, and a random mixture between different groups.

David Fissman of the University of Toronto’s Dalla Lana School of Public Health said:

“But the choice of those who stopped vaccination has been found to contribute disproportionately to the risks of those who have been vaccinated,” Fissman said in a statement.

The study, published in the Canadian Medical Association Journal, found that a mixture of unvaccinated and unvaccinated had a lower risk to vaccinated people.

However, the mix of vaccinated and unvaccinated people creates a significant number of new infections in vaccinated people, even in high immunization scenarios.

Findings remained stable even at low levels of vaccine efficacy to prevent infection, such as in people not receiving booster doses or using the new SARS-CoV-2 mutant.

According to researchers, the findings may be related to future waves of SARS-CoV-2 or the behavior of new variants.

“The risk of unvaccinated people is not considered self-respecting. In other words, quitting vaccination affects not only the unvaccinated people but also those around them. Is unthinkable, “said the author of the study.

“Fairness and justice considerations for those who choose to be vaccinated and those who choose not to be vaccinated need to be considered in the development of vaccination policies,” they said. ..

Researchers have found that feelings of opposition to vaccines, partially fueled by organized disinformation efforts, result in suboptimal intake of vaccines readily available in many countries, adversely affecting health and the economy. I pointed out that it is exerting.

The decision not to be vaccinated is often constructed in terms of the individual’s right to opt out, but such discussions ignore the potential harm to the wider community due to inadequate vaccination. They added that they were.
