Bellini et al.’s single-center study included 467 patients who underwent chest CT between December 15, 2021 and February 18, 2022, during hospitalization for symptomatic COVID-19, identified recognized by reverse transcriptase polymerase chain reaction assay.
216 patients were unvaccinated, while 167 and 84 patients were fully immunized — after receiving a second dose at least 14 days before diagnosis of COVID-19 — with either the BNT162b2 mRNA vaccine or the vaccine. ask for ChAdOx1-S adenovirus vector, respectively.
The incidence of pneumonia-free disease was 15% in unvaccinated patients, compared with 51% and 29% in fully vaccinated patients with BNT162b2 and ChAdOx1-S vaccines, respectively. In addition, mean CT-SS in unvaccinated patients was significantly higher than in fully vaccinated patients with BNT162b2 or ChAdOx1-S vaccines.
“Visual radiographic observation of the protective effect of vaccination on lung injury in patients with sporadic infections provides further evidence supporting the clinical benefit of vaccination.“, the authors of this AJR paper reiterated.
