A little over 25 per cent of healthcare workers were infected with Coronavirus despite getting fully vaccinated, a recent study has revealed, giving an insight on the breakthrough infections due to the Delta variant. The study, jointly conducted by the Institute of Genomics and Integrative Biology (IGIB) and Max hospitals in Delhi-NCR, found that vaccination breakthroughs were far more common during the Delta-outbreak in Delhi than previously reported.

However, the severity of the infection was low and vaccination is crucial to avoid severe illnesses, said Shantanu Sengupta, senior scientist with the IGIB and one of the lead researchers of the study. He also cautioned that of the 25.3 per cent who were infected, a large number were asymptomatic, so masking up is also crucial to arrest the spread of infection.
