Among 39512 health care workers vaccineted with both doses of COVID-19 vaccine; those who developed COVID-19 infection ≥14 days post 2nd dose were included in the study. Total 124 participants till 30 Jun 2021 fulfilled the criteria of COVID-19 vaccine breakthrough infection and were analyzed.

Results: Mean age of the participants was 38.8 ± 11 years. Males were 69.4% while females were 30.6%.

Asymptomatic/mild infections were reported among 94.4% and only 5.6% had moderate disease. No severe/critical disease requiring oxygen supplementation or ventilator support was observed.
