Published recently in the prestigious New England Journal of Medicine (NEJM), a study led by Massachusetts-based physician-scientists leads to a disturbing discovery: individuals fully vaccinated and boosted against COVID-19 actually recover markedly more slowly from the illness and surprisingly, even remain contagious for lengthier periods of time as compared to unvaccinated persons. While the study didn’t investigate implications associated with illness severity, the findings nonetheless raise significant questions for consideration. This study was approved by the institutional review board and the institutional biosafety committee at Mass General Brigham, and informed consent was obtained from all the participants. The takeaway from this study could be profound should the results scale out to larger cohorts. People that are vaccinated remain five times as contagious as those who are unvaccinated ten days after SARS-CoV-2 infection. Put another way, the vaccinated continue to transmit the disease significantly more than the unvaccinated should the data hold up across broader investigation.
