EFFECT OF PRIOR COVID VACCINATION ON LUNG INVOLVEMENT IN COVID PATIENTS
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.
