INTRODUCTION: gen Tests
(RAT), but radiological imaging also plays an important role in diagnosing and severity assessment of the disease. The
extent of lung involvement and consequently the severity of the COVID can be assessed by the CT Severity Scoring.
MATERIAL & METHODS: This was a retrospective study done at a tertiary care centre in Uttarakhand to compare lung involvement and
radiological features in COVID vaccinated and unvaccinated groups. CTSI score of CT chest of the patients was done.
RESULTS & DISCUSSION: Out of 50 subjects, 32 were never vaccinated, 9 were vaccinated with a single dose and 9 subjects had been
vaccinated by 2 doses. CTSI Scoring of each CT scan was done. Average CTSI score was 11.7, overall. CTSI score for non-vaccinated was 15.28,
CTSI score for vaccinated was 5.39. CTSI score for single dose COVID vaccinated subjects was 7.22, while CTSI score of subjects who got both
shots of vaccine was 3.56.
CONCLUSION: In vaccinated individuals, the disease is restricted to the lower lobes. COVID patients who got both shots of COVID vaccine
were less prone for lung damage, and hence had milder disease compared to non-vaccinated patients of COVID-19.
