Dr Shrushti Halari
Mumbai: A 26-year-old Mulund-based doctor has tested positive for Covid-19 three times since June 2020, twice after she got vaccinated earlier this year, reports Malathy Iyer. “The reinfections are confusing,” said Dr Shrushti Halari, whose swab samples have been collected for genome sequencing as part of a citywide study on breakthrough infections (occurring after a person is vaccinated).
While there are no clear answers for why the doctor got Covid thrice, doctors told TOI that the reasons could range from SARS2 variants to her immunity levels to an incorrect diagnostic report (though RT-PCR is the gold standard for Covid-19 testing, it has a sensitivity of around 70%-75%).
