evidence: Amid new COVID-19 research indicating serious health risks for unvaccinated children, Sandra Fryhofer, MD, can’t underscore this point enough: vaccination matters. [...] Compelling findings published in the CDC’s Morbidity and Mortality Weekly Report underscore the health risks associated with unvaccinated children. [...] A study of 12–18-year-olds demonstrated that a two-dose series of Pfizer-BioNTech vaccine, the only vaccine authorized for children, was 91% effective at preventing MIS-C. Among those children hospitalized with MIS-C, 95% had not been vaccinated. None of the vaccinated children required respiratory or cardiovascular life support, compared with 39% of unvaccinated children with MISC.
