COVID-19 vaccines have been found to be efficacious for preventing severe disease, yet breakthrough infections and deaths have occurred in a small proportion of vaccinated individuals. This study aimed to describe the vaccination status and comorbidities of COVID-19 all-cause deaths.This descriptive observational study was conducted at a tertiary care center in western India. A total of 310, RT-PCR positive COVID-19 deaths, aged 45 years and above irrespective of the cause of death (all-cause mortality), were included in the study. Death after breakthrough infection was defined as death in patient with disease onset after 14 days of the second dose of vaccine.Diabetes was the most common comorbidity found in 17.1% of the deaths, followed by hypertension. Cardiovascular disease and renal disease were other common comorbidities seen in 8.7% and 4.83% deaths respectively. Other less common comorbidities include neurological disorders, HIV, autoimmune disorders. Out of these 310 deaths, 21.4% of patients developed disease within 14 days of the first dose. Death after true breakthrough infection (after 14 days of both doses) was seen in only two patients (0.6%). One of these two patients was aged 60 years and had diabetes, while the other was aged 72 years and had a history of smoking.Diabetes and hypertension were the most common comorbidities, indicating a higher risk of mortality among comorbid patients. Only a small proportion of deaths (0.6%) occurred after breakthrough infection beyond 14 days of two doses. COVID-19 vaccines have shown promising efficacy against severe disease, thus high vaccination coverage needs to be achieved to prevent morbidity and mortality. |
