Indian police yesterday said that around 2,000 people were injected with fake Covid-19 vaccines in Mumbai, and another 500 -- some of them disabled -- may have suffered the same fate in Kolkata. Police in Mumbai said that people who thought they were being vaccinated were in fact injected with a saline solution. Ten people have been arrested including two doctors at a private hospital in the financial hub. Police in Kolkata meanwhile have arrested a man posing as a civil servant who reportedly ran as many as eight spurious vaccination camps. How many fake jabs he administered is yet to be known.
