25% fresh infection among fully vaccinated Delhi hospital healthcare workers: study

None of nearly 600 vaccine recipients, however, reportedly required hospitalisation

In an indicator of the diminishing role of vaccines in preventing transmission of the coronavirus, a little over 25% of the fully vaccinated healthcare workers of a Delhi hospital contracted a fresh or ‘breakthrough’ infection. None of the nearly 600 vaccine recipients, however, reportedly required hospitalisation. While previous reports of similar infections have been reported in other studies in India, this is the first time that such a high percentage has been reported as part of a single study. The study involved healthcare workers at the Max group of hospitals in Delhi and Gurugram and was led by scientists at the CSIR-Institute of Genomics and Integrative Biology (CSIR-IGIB). It appears as a preprint and is yet to be peer-reviewed. The timing between the first and second dose varied, but 482 received the second dose within 42 days of the first dose. About half the recipients had been previously infected with SARS-CoV-2.
