People who have not received the COVID-19 vaccine may present a “disproportionate risk” to vaccinated individuals, according to a new study that is missing key factors before drawing conclusions..Published on Monday in the Canadian Medical Association Journal, the study’s message is the choice to get vaccinated can’t be thought of as merely personal..A mathematical model was created to compute a hypothetical number of interactions between unvaccinated and vaccinated people based on Ontario data..It included different states of having the virus (susceptible, infectious, recovered) and different levels of immunity for vaccinated and unvaccinated people..Non-concrete factors — such as immunity levels and the transmission rates from vaccinated persons — were used in the study to draw conclusions, noted the authors of the study..From the factors in the model, findings included:.“Choice of some individuals to refuse vaccination is likely to affect the health and safety of vaccinated people in a manner disproportionate to the fraction of unvaccinated people in the population.”The choice to be unvaccinated cannot be considered self-regarding.“Considerations around equity and justice for people who do choose to be vaccinated, as well as those who choose not to be, need to be considered in the formulation of vaccination policy.”It is unlikely COVID-19 will be eliminated, these findings are likely to be relevant to future epidemics and new emerging variants..The study is done under the auspices of when “vaccines confer imperfect immunity.”.The model assumes the part of the population who are vaccinated have 80% immunity to COVID-19, while unvaccinated people are considered to have 20% immunity..The study did not take vaccinations waning immunity into consideration..The authors of the study noted they most likely underestimated the benefits of vaccination in preventing virus transmission..Government-funded mainstream media outlets all published stories with the findings, but did not elaborate on the parameters used.. March-pt.-2-standard-graphics-11April 25 headlines, courtesy of the Western Standard .The articles shown above outline the findings under the model’s conditions and do not explain those theoretical conditions..The study’s lead author, David Fisman, from the University of Toronto, told Global News the way COVID-19 works means everyone is connected, and “we have to rely on public health for things like this.”.Fisman said the idea for the study came a few months ago as many debated on vaccine passports and vaccine mandates..“We thought what was missing from that conversation was, what are the rights of vaccinated people to be protected from unvaccinated people?” said Fisman..“At the end of the day, this is about collective action. The decision to get vaccinated can’t be framed as just a matter of personal choice because it has implications for the safety of other people in the community.”.The study says “anti-vaccine sentiment” is contributed by “organized disinformation efforts.”.The unvaccinated are to blame for “sub optimal uptake” of COVID-19 vaccines in the population and “adverse health and economic consequences,” according to the study..“Non vaccination is expected to result in amplification of disease transmission in unvaccinated sub populations, but the communicable nature of infectious diseases means that this also heightens risk for vaccinated populations, when vaccines confer imperfect immunity,” reads the study..Fisman sat on advisory boards for Pfizer, AstraZeneca, Seqirus and Sanofi-Pasteur Vaccines..Fisman has also served as a legal expert on COVID-19-related issues in Ontario, for the Registered Nurses Association of Ontario and the Teachers Federation of Ontario..Co-author Ashleigh Tuite was employed by the Public Health Agency of Canada while the research was conducted..The study was funded by the Canada Institutes of Health Research, run by the Government of Canada..The study did not mention any risks associated with COVID-19 vaccines..Mathematical modeling and COVID-19 predictions were found to be tricky and in need of extremely specific factors, according to a different study which modeled then later followed up on COVID-19 trends in 2020..The Values and Limitations of Mathematical Modelling to COVID-19 in the World: A Follow Up Report, said “a truly useful model tool will need to incorporate more dynamic data” and “data shortage made such comprehensive effort very challenging.”.The University of Toronto and David Fisman did not respond to media inquiries from the Western Standard..Ewa Sudyk is a reporter with the Western Standard.,esudyk@westernstandard.news,.https://twitter.com/EwaSudyk
