Covid-19 vaccination at BLW on Saturday Varanasi: Shortage of RNA extraction machines and data entry operators as well as slow network connectivity cited by the officials of Banaras Hindu University and SPG divisional hospital laboratories is not only delaying Covid-19 test reports by five days to over a week, but also complicating the response to the second wave of the pandemic in Prime Minister Narendra Modi’s parliamentary constituency. When officials at BHU labs were contacted on Saturday, they claimed that after receiving the samples through the office of the chief medical officer, they took about 48 hours in preparing the report.
